Executive Summary

Network requirements are changing on a regular basis. Not too long ago you could only have a wired network connection. If you wanted to make that existing connection portable you simply just connected a longer cable to your computer and dragged it around the office. This contributed to a mess of unsightly cables and multiple connections around an office space that could be connected and reconnected as office layouts changed over time. Even just a few years ago a wireless network was not even worth the effort because of the slow connections and download speeds. Now every coffee shop offers wireless internet with speeds faster than the wired networks of 10 years ago. The company at discussion, You’re Free Inc. is a small law firm that has just experienced some growth and doubled its employee roster as well as double its office space from one floor to two. It is currently using a very slow 10Mbps network to access applications on its server and do video conferencing. As you can imagine there is a big slow down in the network and high latency is experienced during a video conference and during peak business hours. Some employees have even suggested flex scheduling in order to get more work done, as the amount of people using the network will be spread out across the day. The company has finally decided to create a budget for the installation of new network. This network will replace the drinking straw sized 10Mbps network with a sewer sized 1000Mbps network with integrated wireless connectivity. The wireless connectivity will take the existing, well equipped Windows 7 laptops that everyone has and “cut the cord”. This will get rid of the clutter of cable strewn around the office, no more tripping hazards, no more duct tape on the carpet. Users will be free to connect in one office and carry their laptop or tablet from one office to the next.
Project Scope

You’re Free law firm incorporated (You’re Free Inc., You’re Free, or the firm) has experienced a large amount of success in the area of defense law over the past few years. Representing clients that were able to afford large billing amounts have allowed You’re Free to expand its enterprise from a one floor, fifty employee law firm to a two floor, one hundred employee law firm. With this growth, the firm needs to expand its networking capabilities. The company has decided that expanding its current wired network configuration to the second floor would be costly and time consuming. It has been recommended that the firm look into deploying a wireless network.
If You’re Free decided to expand the existing traditional wired network it would incur the expenses and time to install the infrastructure. You’re Free would have to run Ethernet cable to each point of access where the network would be utilized. Each office would need a connection at each desk and near the client meeting table within the office. The secretaries would need a connection to the network at their desks and finally the conference rooms would need multiple connections for meeting where there may be multiple computers connected to the network during meetings and presentations. Essentially, over one hundred additional network access jacks need to be installed on the new floor. Each of these terminations would need to be connected via a switch or router to the servers and the internet. In order to accomplish this, thousands of feet and cable, and additional equipment including a router and switches are needed to complete the infrastructure. On top of the equipment expense, electricians and network specialists would have to spend time installing the network. The installation alone could take more than a month to complete. The firm needs to have access to the network as soon as possible because the new attorneys have clients and they are sharing the older space with other attorneys, which is causing the firm to have an unprofessional appearance.
Deploying a wireless network would avoid the expense of large expanses of Ethernet cable, and associated hardware, and electricians needed to upgrade and expand the network. The wireless network would require less equipment, provide freedom of accessibility among the authorized users and can be deployed in less than a month. This will save the company thousands of dollars over the installation of a traditional Ethernet network infrastructure, while providing the same level of security the company has enjoyed with the current network.
Project Goal

A wireless network needs to be, not only operative, but efficient, and dependable. After the new wireless network has been installed, the network will need to be tested with a protocol analyzer to assure that the network is efficient and dependable for all the users that are required to use it. The wireless network we’ll be using are 802.11n radio transmitter and receivers in each of the laptops that will be provided to each of the employees of the company and for those who do not require laptops; wireless 802.11n network adapters will be installed in desktop computer models. When all of the employees are accessing the network during prime hours between the hours of 9am and 5pm, each laptop will have a have a minimum speed of 50 Megabits per second (Mbps). This will assure that each computer will have the required signal strength to receive and transmit data. All of these tests will be run during the peak hours as described above. When performing a wireless network analysis it is important to define the range boundary of an access point based on signal-to-noise (SNR) ratio, which is the signal level (in dBm) minus the noise level (in dBm). During peak hours the SNR will have a signal of no less than 25dB. This will aid in the transfer of information from the user to the server or to the internet at very fast rate (Geier, 2008). Successful transmissions of bits are also an indicator of how healthy a network is. The bit error rate (BER) can be measured using a network analyzer. The BER is the number of incorrectly received information bits divided by the total number of received bits of information. A good threshold for considering errors unhealthy is that a network should not have more than one bad frame per megabyte of data (Oppenheimer, 2011). The above suggested performance measurements will be used to determine the success of the installation and performance of the network. In addition to these measures all one hundred employees of the firm will be trained on how to access the servers and all of the information they need to properly conduct their business as well as utilize the security software to conduct business safely.
The timeframe for completing the installation after the network design has been improved will be less than 1 month. This should give adequate time to install the equipment, configure the connection to the servers and internet, and optimize the performance.

Design Requirements

You’re Free is a bustling law firm that is constantly growing its clientele. Although the firm is expanding its business, it cannot justify the cost of hiring a full-time IT employee. It also, should not be involved in as many problems with this network to need a full-time IT employee. Therefore, the firm can afford to have an employee to be an administrator of the network on a part-time or less than part-time basis. Ideally, the network needs to be straightforward and easily managed.
The network must allow members of the firm to share information, as well as printers and other peripherals. The needs can be met with a single local access network (LAN) with one or two servers. In our case we will start with a single rack-mount server and possible expand this in the future as the company grows. This network can be managed by one person with only moderate technical knowledge and experience.
The firm’s employees will need shared access to word processing files, multiuser databases. They will also need to access Email services and the Internet. This will make the network all encompassing, so that all users will be able to access all files and programs as they pertain to their position at the firm.
The initial design for the network will plan for the future by building in extra storage capacity from the inception of the wireless network. This will allow the network to grow with You’re Free over the next two to three years. The network will grow easily with the company.
The network server will offer file services. With this network, a server will be set up to store data in such a way that it can be shared by any person in the organization. File servers are the network computers that specialize in providing shared data storage. Through the interface built into the file server’s network operating system, a network administrator can set up a variety of shared folders, and control access to them. The file server will also offer a private folder for each user. Data stored in that folder will not be visible to any other network user. Shared folders also will be created that can be accessed by several individuals. For each shared folder, the network administrator will determine who can read its information and who is allowed to create or modify it. When all shared folders reside on a centralized server, it is relatively easy for users to know where to go to find them. The networking operating system that will be installed will offer an easy to use graphical user interface for controlling access to the information stored on the file server (Breeding, 2011).
The network server can provide all kinds of service that are integrated into the unit and are controlled by the network server operating system. One of these is print services. The firm will want the ability have several individuals be able to print to a single printer. It will be far more efficient to purchase one or two high-end printers than to purchase low-end printers for each individual computer. The network operating system will be able to manage network printing (Breeding, 2011).
A web server will be implemented into this network. Given the trend toward Web-based computing, the firm wants to consider the possibility of this service in the future. The firm wants to create a web server for their network. Web-based systems provide efficient ways to share information, either within the company’s private network or externally via the internet.
There are applications that need to be accessed by many employees within the firm. These applications are large and require a significant amount of RAM to operate efficiently. It would be difficult to maintain these applications on each individual PC. When there are updates to the applications, it would be easier to update the application on the server in one location, than to update each PC. Also, if there is a need for a directory change, where the application stores this data, it will be easier to update the application on the server.
Design Requirements – Assumptions

* The company’s clientele base is growing * No intentions of hiring a full-time IT employee * The employee managing the network has little technical expertise * The company can only afford a single server at this time * Employees need access to: * Shared access folders * Internet * Email * Employees may need to access files and applications remotely from the internet in the future as the company continues to expand. * There are large applications that will need to be updated on a regular basis.
Current State of the Network

You’re Free Inc. has a network that barely meets the current needs for data management and sharing of peripherals among the original 50 employees. Now that the company has doubled its employee roster to 100 and doubled its real estate from one floor to two floors, the company has decided to increase the availability of the network and update the technology to provide the access. First we need to analyze the current network, its physical and logical layouts, and its performance. The current network is laid out in a modified hierarchical hub-and-spoke design. There is a central router similar to that of the D-Link DI-704P (amazon.com, 2011) that is the heart of the network that routes the data between all of the locations, workstations, peripherals, and the internet. There is a two tier hierarchy between the router and the east and west end workstations and peripherals. This is advantageous because if one of the switches closest to the workstations and peripherals became inoperable, only half of the building would be disabled. The servers are connected to the central router by another switch. This makes accessing the servers more efficient. There are two servers; one of the servers functions as a Print Server, Domain Name Server (DNS), and Dynamic Host Configuration Protocol (DHCP) Server. The other server functions as an application server, File Transfer Protocol (FTP), and data storage server. A DNS is used for translating names of network nodes in addresses. A DHCP provides a mechanism for allocating Internet Protocol (IP) addresses dynamically to minimize configuration and allow addresses to be reused when host no longer need them. FTP is an application protocol that is part of the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol stack, used for transferring files between network nodes (Oppenheimer, 2011).
The current system components are connected to each other using a 10 Base-T Ethernet backbone using cable made of unshielded twisted pair (UTP) wire. The twisted pair wire that is used is similar to that of ordinary voice-grade wire. 10 Base-T supports up to 10 Mbps transmission speed (Ryland, 2000). The Ethernet link supports simultaneous transmitting and receiving of data, which is called full-duplex Ethernet (Oppenheimer, 2011). This Ethernet configuration is insufficient to provide speed of data transmission between the 50 employees that are currently working at the firm. There are other criteria that have been used to determine the health of the existing network. These are the measures we used to determine the health of the network: * Performance * Availability: The amount of bandwidth available * Bandwidth utilization: The percent of the total available bandwidth capacity in use * Accuracy: The amount of useful traffic that is correctly transmitted, relative to total traffic * Efficiency: an analysis of how much effort is required to produce a certain amount of data throughput * Response time: The amount of time between a request for some network service and a response to the request (Oppenheimer, 2011). * Status of major routers, switches, and firewalls * Mean Time Between Failure (MTBF): The failure rate of a product during its normal life. * Mean Time Between Repair (MTBR): The basic measure of reliability for a repairable system. It is a measure of average time between all repairs for the system (Levin & Kalal, 2003).
The network utilization frequently exceeds the 70% optimum threshold that is a sign of a healthy network and that data is being transmitted efficiency across the network. The bandwidth of the network, which is the maximum capacity the network can transmit, is 70%. The throughput should ideally be the same as the capacity of the bandwidth (Oppenheimer, 2011). In this case the throughput is lower, right around 50%. This is because of the amount of lost packets being observed on the network. When the network was tested with a traffic generator using packet sizes between 64 and 1518 bytes at a throughput of 70%, a significant amount of packets were lost. This network experiences high latency quite frequently. Latency is the delay between the time a device requests access to a network and the time it is granted permission to transmit (Oppenheimer, 2011). Efficiency specifies how much overhead is required to send traffic. The network being a relatively older one using 10Mps Ethernet is relatively inefficient, the bandwidth and throughput are not optimal for sending frames with large headers. During peak times and 80% or more of the employees are using applications such as QuickBooks and video conferencing software, there are usually complaints of the network being very slow. This is due to the lack of data that can be transported across the older 10 Mbps network. This network was sufficient when a small amount of data and text files where being transmitted. Now there are applications that require more bandwidth, such as the video conferencing software, and downloading of larger internet files, which require more bandwidth to operate efficiently.
The Servers that are connected to the network are stand-alone tower servers. The servers have a single socket motherboard with a 1.5GHz dual core processor, 4GB of memory, and maximum capacity for utilization of 4TB of storage. These servers take up unnecessary floor space and will need to be upgraded in the near future to be able to take advantage of the storage needs of the company as well as having enough processing power to handle the loads of the additional users and the applications that will be executed on a regular basis by a large amount of the employees at the firm.
The current IP address naming that is utilized is called a “Class B” IP addressing scheme. Whereby, there are four octets in the IP address, the first two octets refer to the network id and the last two octets correspond to the host id. Workstations and peripherals such as computers, routers, printers, plotters, scanners, switches, etc. are considered host components that need a unique id, with the exception of routers which need a host id for each port available in the router (Botsford, 1999).

New Logical and Physical Design

The new design for the wireless network is going to be a vast improvement over the current system. Users will have enough speed and response from the network to be able to complete their work quickly and efficiently. This network is designed to allow all users to be able to utilize applications such as video conferencing which reside on the server to performing research either on the internet or electronic copies of law books which reside on the in-house server. The best way to describe the details of this network is to start with the physical design from the outside of the building in towards the servers and user workstations. The internet and connection to the internet will be provided by the ISP. The connection to the building will be a hybrid coax data connection. According to the conversation I had with Comcast business customer service, hybrid coax utilizes a combination of fiber-optic cable and coaxial cable to deliver data to the customer. Fiber-optic cable provides approximately 98% of the data, whilst the coax cable will provide support and stabilization for the system. The coax will be used as a redundancy incase the fiber-optic system fails, it can also be used to boost data speeds when there is a high amount of users on the fiber channels. The data service across the coax cable can be boosted to fill the void from the loss of speed on the fiber channels during peak usage. The ISP data connection terminates in the building at IP DOCSIS (Data Over Cable Service Interface Specification) 3.0 Gateway, similar to the Cisco DPC3825 Gateway. This router will be provided and maintained by Comcast. Once inside the building the data connection from the ISP DOCSIS gateway is connected to a CISCO 2911 router. This router provides routing capabilities as well as an integrated firewall for security purposes. The backbone of the LAN network is a Gigabit (1000 Mbps) based system. All routers and switches are capable of utilizing all of the speed capable across this type of network. There are five CISCO ESW-540-8P-K9 switches. These are small eight port switches that are used to connect to the servers, wireless access points and wireless router. Two CISCO ESW-540-48P-K9 switches, one on each floor, supply a dedicated connection to peripheries such as printers and scanners. Most of the employees will be utilizing the wireless network access using either notebook computers or wireless cards installed in their desktop computers. The wireless connection will be provided by a CISCO 2921 Integrated Services Router. This router provides the ability to connect to wireless access points. This configuration will allow a user to move throughout the office and even between floors and keep a dynamic connection to the network. The wireless router will be connected to four CISCO AIR-AP1252AG-A-K9 Wireless Access Points. These wireless access points provide connection at the most current IEEE802.11n standard. These access points provide wireless data rates up to 300Mbps (Newegg, 2011). One access point will be placed about a third of the way from both ends of the building on each floor.
The space hogging stand-alone servers will be replaced with a rack system. This type of system provides a more organized method of connecting the network, maintaining the network, and saving space by having most of the large components contained on one rack. The servers we’ll be using are three Hewlett-Packard ProLiant BL280c G6 blade servers. These servers will have a single 6-core Intel Processor, 12GB of memory and 1TB of storage each. Data Storage will be provided by a CISCO NSS326D12-k9 Network Attached Storage (NAS) device. The NAS will provide up to 12TB of data storage via six 2TB hard drives (HDD). This will provide security for the data in case one of the servers fails. Also, this will provide a central repository for all of the needed information, so requests will not be made across multiple servers, just one location.
With the combination of faster servers and high speed wireless connections backed up by a Gigabit skeleton, this network will provide the bandwidth to allow throughput to be optimized so that users will experience very little latency when accessing data across the network, using high bandwidth applications such as video conferencing, or researching and downloading information from the internet.
The network is a ring-type network, whereby if one of the two routers fails then the other router will be able to perform routing functions and continue to provide service to the users. This type of redundancy within the network is backed up with a robust routing protocol. CISCO’s HSRP (Hot Standby Router Protocol) will be used to create efficiency and stability throughout the network. The HSRP allows hosts to appear to use a single router and to maintain connectivity even if the actual first hop router fails. Multiple routers participate in this protocol and in concert to create the illusion of a single virtual router. The protocol insures that one and only one of the routers is forwarding packets on behalf of the virtual router. End hosts forward their packets to the virtual router. The router forwarding packets is known as the active router. A standby router is selected to replace the active router should it fail. The protocol provides a mechanism for determining active and standby routers, using IP addresses on the participating routers. If an active router fails a standby router can take over without a major interruption in the host’s connectivity (Li, Cole, Morton & Li, 1998).
DHCP (Domain Host Configuration Protocol) will be used for device address configuration. This service will be provided by Microsoft Windows Server 2008 software that will be installed on the server that will host DHCP. DHCP automatically provides and Internet Protocol (IP) host with its IP address and other related configuration information such as the subnet mask and default gateway (Microsoft, 2011). DNS (Domain Name System) will provide the service for naming computers and network services into a hierarchy of domains. The DNS will be used to locate computers and services with user-friendly names. When a user enters a DNS name in an application, DNS services can resolve the name to other information that is associated with the name, such as an IP address (Microsoft, 2003).
The whole network is tied together overall by CISCO’s Prime Network Control System (NCS). NCS is the industry’s most comprehensive management platform, delivering converged user access and identity management, with complete visibility into endpoint connectivity – regardless of device, network, or location. This will speed troubleshooting for network problems related to end user devices. NCS also provides monitoring of endpoint security policy. Real-time contextual information will be visible from the network, users, and devices across the entire wired and wireless network (Cisco, 2011).

Implementation Plan

The new network is going to be a complete replacement of the existing network, including all hardware and servers. The existing computers that are running Windows 7 are well equipped for utilizing all of the benefits of the new network. Existing printers and peripherals can be adapted to conform to the new network (if needed). The existing network will be used until the new network is fully operational and tested. The New network will be on top of the existing network using already existing cable routes and technical closets and areas for equipment. The cabling for the existing equipment will be removed as feasible, but can be left in place if an additional cost is involved for the removal of the old cabling.
First, the location of the hardware will be determined. Where the routers, switches, servers, and wireless access points will be located will then determine the route the Ethernet cable and lengths required. After the hardware is located then the Ethernet cable will be installed. A 10 foot patch cable will be used to connect the incoming DOCSIS router to the primary router. The primary router will be installed on a rack in the cooled room dedicated to storing the network servers. The rack will contain the primary router, the 3 servers that will function as the DHCP, DNS, FTP, Applications, Web, and Print servers, the Network Attached Storage (NAS), the switch connecting the primary and wireless router to the servers, the switch connecting the servers to the NAS, and the switch connected to the first and second floor switches that provide the network connection to the peripherals. The hardware installed on the rack will be interconnected with ten 3 foot patch cables. The wireless router will be connected to the two switches, one on each floor, connected to the Aironet wireless access points. These switches are connected to the wireless router by two 100 foot patch cables, the wireless access points will be connected to their respective switches with 100 foot patch cables. The wireless router will be connected to the switch that is connected to the servers. In the event the primary router fails, the wireless LAN router will serve as a backup to keep the network functional. There will be no internet access, but in house data transfer will still be possible. The two switches that are dedicated to serving the peripherals will be connected to the rack mounted switch with two 100 foot patch cables. The switch will be centrally located on each floor and will use an assortment of 25 foot patch cables to connect the peripherals. In a real world situation it would be cheaper to buy the cable in bulk and cut the cable to length as needed and crimp on the connectors, but for ease of configuration of this network, patch cables will be used.
After the Gigabit backbone is installed. A computer will be dedicated and hard connected to the network and serve as the point of access to the maintenance of the network. Windows server 2008 will be loaded on each of the servers prior to their installation by the factory. The CISCO Prime Network Control System (NCS) will be installed on the primary IT computer. All of the hardware connected to the network at this point will be identified and configured within the NCS. The NCS will give the IT manager immediate access tools needed, they will be able to monitor the LAN, view user endpoints across the network from this computer (CISCO, 2011). The entire installation of the network is scheduled to take no longer than 30 days from the beginning of the installation of the Ethernet cable to the final initial testing of the LAN connections and data transfers.
After the initial testing of communication between the servers, the IT computer and verification of wireless access, copies of data can be moved to the NAS, and applications can be installed on the server. Using Windows Server 2008, the DHCP and DNS servers can be identified. After the DHCP and DNS Servers have been set up, workstations and peripherals can be moved from the old network to the new network. For a brief period each network will be in operation. After everyone is transferred from the old network to the new network the data files from the old server will be merged with the data on the new server to make sure no information is lost. Prior to a computer being installed on the network, Norton Business Suite will be installed on each computer. Norton comes has a courtesy protection from Comcast with all business accounts. The free version that comes with the subscription is more than adequate for our needs. The Norton suite will protect against viruses, spyware, Trojan horses, worms, bots, and rootkits. It also protects against infected websites, protects identity online, and guards against keyloggers with automatic logins and form filling (Comcast, 2011).
As each computer comes online the DHCP server will assign the computer or peripheral with an IP address and the DNS server will allow naming of the device and keep track of the name of the item and its associated IP address and subnet mask.
There will be someone on staff during normal business hours in case there is an internal problem with the network. The mean time to respond (MTTR) is less than 15 minutes. The mean time to repair (MTTR) depends on the manufacturer of the equipment and how they take to have service come to repair or replace the part. The wording of the service contract will include that if a service person is not available to respond on the day of the event, then a replacement part will be delivered by the next day and will be installed by the IT manager. For external issues, all service up to and including the DOCSIS router will be handled by Comcast. Comcast’s MTTR (respond) is within 15 minutes of receipt of fault. Comcast’s MTTR (repair) is 4 hours for electronic equipment and 6 hours for fiber equipment (Comcast, 2011).
Relatively little training will be needed for personnel on the new network except with the possibility of server locations and drive lettering. Most of the employees are experienced enough with using the network that the acceptance will be relatively easy with very little loss in productivity due to the new transition. All users will be impressed with rapid increase in the ability to receive and exchange information.
Budget

As with any other company, money and budgets is always an object of contention. Everyone wants the newest and greatest, but when it comes to the money it always seem to be a sticking point to the implementation of the plan. Often spending money to create efficiency and build a business is necessary. The President and the chief accountant of You’re Free Inc. are in control of the budget for this project. Any finalization or additions to the budget must be mutually agreed upon by the President and the chief accountant. When the network was designed there were some additional features in the design that where nice additions but were decided unnecessary at the initial installation of the new network and will be decided upon at a later date if they are needed. Here is a breakdown of the items that will be included in the network and the total of all the items will be the first years of expenses of the new network. Equipment | Price | Total | CAT 5 cable + installation | 28 x $125.00 | $3,500 | CAT 5 patch cable (3 feet) | 10 x $7.99 | $79.90 | CISCO Hot Standby Router Protocol (HSRP) | $0.00 | $0.00 | CISCO Prime Network Control System (NCS) | $5,295.00 | $5,295.00 | Comcast Internet Service | 12 x $812.04 | $9,744.08 | CISCO 8 port switch | 5 x $522.99 | $2614.95 | CISCO 48 port switch | 2 x $1,912.99 | $3,825.98 | CISCO WLAN router | $2,691.99 | $2,691.99 | CISCO 2911 router (primary) | $1,598.99 | $1,598.99 | Aironet Access Points | 4 x $740.99 | $2,963.96 | HP Proliant Server | 3 x $2,130.99 | $6,392.97 | CISCO Network Attached Storage (NAS) | $3,995.99 | $3,995.99 | 2TB Hard drives | 6 x $199.99 | $1,199.94 | Rack | $499.99 | $499.99 | Shelves for rack | 9 x $99.99 | $899.91 | Windows Server 2008 | 3 x $2,000.00 | $6,000.00 | External Control licenses for Windows Server 2008 | $1,270.00 | $1,270.00 | Norton Security Suite | $00.00 | $00.00 | Total 1st year expenses | | $52,574.05 + tax |

We were fortunate to get some of the products we needed at no cost. Norton Security Suite is included with our Comcast Business account as the Internet provider. Anti-virus software is critical to the health and safety of the network. Also, CISCOs HSRP software is integrated in to the routers and switches that we are purchasing and any additional controller software can be downloaded for free from the website (CISCO, telephone conversation, October 5, 2011). As far as the licensing agreement with Microsoft goes, it is a complex licensing structure, it will cost $2,000.00 for each server and then there will be a cost of $1,270.00 for the users of the network to access the contents of the server. The Ethernet cable installation cost is a flat fee for lengths 100 feet or less. We only need 28 cables installed the reminder of the cables will be patch cables that are used to connect equipment within the rack and from the wall plate to the item.
There are two wireless access points in the main hallways on each floor. This level of access is sufficient for individuals accessing the network. However, a concern was raised about maintaining a connection to the network when traveling in between floors. As some employees frequently move between floors for meetings or other reasons, it would be frustrating to lose a connection and have to wait to reconnect when entering the other floor. A suggestion was raised to have access points in the stairwell at each end of the building and possibly within the elevator, so that individuals using a laptop or a tablet can discuss items with groups while moving throughout the building. At this time it was deemed a non-priority by the budget team and will be addressed at a later time if it appears that there is a need for individuals to maintain network connection between the floors.
