Introduction Since Retail Technologies Incorporated’s conception, we have witnessed a rapid growth both internally and externally. This includes providing support as well as multiple services to other organizations such as Duane Reade Corporation located in New York and Peavey Mart Stores, Inc. located in Canada. This sudden influx of added responsibility has certainly caused the IT department to take a closer look at our network as a whole. The Retail Technologies current network infrastructure consists of a basic LAN configuration which includes a non server based workgroup environment. Each PC can connect securely through the VPN via an IPSec and PPP connection. The PPP technology establishes a direct connection by utilizing serial cables, phone lines, trunk lines, cellular telephones, specialized radio links, or fiber optic links. In addition, a wireless connection is also available to execs which allow our employees the ability to gain access to the network from outside of the facility. The bandwidth capabilities include Circuit Switching technology as well as a T1 connection which accommodates a total of six departments within the organization. This includes our Project Management Team, Accounting, Customer Service, the Development Team, and the directors and executives. With regards to the security side of the network, very limited measures are implemented to ensure a safe business environment. A Cisco PIX 515E Security Appliance is used as a firewall to protect against any outside threats and maintains Application Layer policy enforcement. This particular device is the only preventative precaution we currently posses that ensures proper network safety. The telecommunication devices that we are presently using are the traditional land-line phone system. Network hardware consists of the Cisco SLM248G 48-Port 10/100 Gigabit Smart switch and the Cisco SR 520-T1 secure router.

Customer Introduction
Although the Retail Technologies overall network appears to be functioning at a satisfactory level, there are various reasons why the need for an improvement remains vital to this company’s future. As you may well know, in order to meet the demands of our clients, we must adapt to changing technological advances such as VOIP, video conferencing, and instant messaging as well as decreasing the strain on network utilization from all employees. In addition, the lack of outdated hardware such as Routers, Switches, and other devices make it that much more difficult to maintain superior performance, reliability, and resiliency to the network. The final reason for this upgrade pertains to network infrastructure security. Due to the limitations of how we can incorporate more advanced securable functionality and manageability to the system, has resulted in a vulnerable and compromised environment. Based on the various statements listed above in the previous paragraph, the following recommendations are necessary for the Retail Technologies network. They include increasing the bandwidth from a T1 line to a T3 which will certainly allow the network to be much more robust, not only for our present situation but also in the future and beyond. The second improvement that must be addressed is to conduct an up-grade to all network hardware such as routers, switches, and the integration of a VOIP phone system. The topology will consist of an Access Layer, distribution layer, and a core layer. In addition, a complete server based environment which includes an Avaya S8300D, AS400, and the utilization of a Windows Server 2003 application which would act as an Active directory and a domain controller. The final portion of this solution is to increase our network security.
Organizational Goals In a conscious effort to maintain customer satisfaction and network longevity, specific organizational goals must be outlined as well as enforced within all departments. Changing our current non-integrated hardware devices to a single piece of equipment that is capable of handling voice, video, and data, would ultimately reduce costs throughout the company. Many individuals from each department have recently complained about the lack of customer service we are supplying to our clients. Improving customer support remains to be an ongoing goal that must be monitored on a daily basis. By introducing document automation will allow the business to tailor to clients’ communication needs, simplify production, and maintain a high quality throughput. Another organizational goal is the daunting task of increasing our customer base which has been suffering at the hands of the sluggish economy. We must begin to take a worldwide approach with regards to advertising, which consists of aggressively using different search engines such as Yahoo, Google, or MSN. The final goal is to increase our cash flow and stray away from our traditional business practices which include designing products for temporary usage. We need to manufacture products that require the client to consistently utilize on a daily basis such as a highly sophisticated application and request the payment if full prior to offering services.

Organizational Constraints In today’s challenging economic times, many companies are facing various constraints that hinder their ability to succeed and remain profitable. Retail Technologies Inc. is no exception and is experiencing difficulties with regards to budget, personnel, policies, as well as scheduling. Our projected budget for the network upgrade is set at $250,000 but due to the lack of company funds, the probability of accepting a revised plan for $200,000 will most likely be inevitable. Another constraint on the horizon is a low level of personnel that will be needed for our expanded network. Several managers within each department are currently in the process of hiring an additional ten employees throughout the year. Choosing a reputable vendor to handle all network support requires a great deal of research and presents an issue for the IT department. I believe that due to the fact that our newly designed network will consist of primarily Cisco products, the obvious choice would have to be the equipment’s manufacturer. The final constraint that becomes apparent is deciding what applications we should implement as well as the time frame. We are currently planning on introducing all new applications such as IP telephony, video conferencing, and email from Microsoft within the next twelve months.

Technical Goals of Existing Network Although organizational goals and constraints provide vital information as to what our strengths and weaknesses are, the network criteria is just as important to the company’s future. There are various goals associated with our current infrastructure which must be adhered to as well as implemented before incorporating an upgraded system. This includes the performance, security, availability, modernization, scalability, and manageability. Network performance in both the LAN and WAN environments has a high priority level of importance and remains to be on the forefront within the design process. With regards to security goals, all inbound and outbound critical data must be protected at all costs. According to Kaminsky, W. (September 18, 2010), “Appropriate network security is achieved when a user has to go through several layers of security before being able to access the desired network. The more layers the system has, the more secure it is.” Availability is another goal which must be taken into account and plays a vital role in our network design. Although networks in general typically experience various problems, the overall objective is to ensure that our system remains as close to 100% as possible. The next goal we would need to consider is adapting the network to advanced technological innovations which include VOIP, multimedia and video conferencing. By keeping up with these changes will ensure that our system stays current and modernized. Scalability also remains to be top priority when integrating upgrades to our network as well as further expansion. Our current infrastructure certainly has reached its full capacity and provides no room for possible advancement or growth. The final goal for our current network is to provide an increase in manageability and reliable maintenance procedures. These steps must be continuously maintained in an effort to reduce any system failures as well as any other issues.

Technical Constraints of Existing Network Various technical constraints continue to exist throughout our current network and are beginning to affect not only each department but our company as a whole. Bandwidth availability as well as speed has always remained to be a thorn in our side for quite some time now. The current LAN environment is operating at 100Mbps and the WAN side is running at 1.544Mbps, all of which is putting an enormous strain on the entire data flow. In addition, the decrease in overall network speed is causing unwanted bottlenecking as well as latency. Application compatibility is another problem we are facing, which makes it very difficult to introduce any new software programs within the company. As a result of this, we cannot utilize the full potential of certain applications such as video and limited instant messaging capabilities. According to DiNicolo, D. (July 04, 2007), “The applications currently used by an organization can have a significant impact on a network design project. For example, the customer may rely upon a particular program that can only function using a specific protocol like NetBEUI.” The final constraint consists of a lack of technical knowledge among the company’s personnel to help ensure a safer network environment. This includes preventing virus attacks, e-mail safety, and proper security procedures. The company must provide additional training to each individual within all departments regarding these methods to protect against network mishaps.

Existing Network Design Analysis

The overall existing design consists of four separate networks which include the headquarters in Atlanta and branch offices located in Florida, New York, and Canada. Retail Technologies network design in Florida utilizes a T1 connection that supplies bandwidth to all departments within the organization. With regards to security, a Cisco PIX 515E appliance is used as a firewall to protect against any unwanted visitors. Wireless connectivity can be accessed by various employees from outside the corporation. Each computer system can connect securely with VPN, IPSec, and PPP connection. The network design located in Canada operates very much the same as the Retail Technologies LAN but has an inadequate amount of bandwidth which is caused by a 56k modem. In addition, the decreased connection is then magnified by 29 stores. The company located in New York implements the same design concept as the Retail Technologies network except for some minor modifications. They include using a domain name server as well as a traditional server as opposed to the Retail Technologies network which is based off a workgroup no server environment. An additional firewall is implemented as well for the New York branch for added security. After researching many aspects of this existing network design, my final analysis indicates that there are an increasingly amount of discrepancies which certainly requires improvement. The issues specifically include insufficient overall network speed, a significant lack of security measures, and no ability to incorporate more advanced technologies. It would seem like a T1 connection will suffice for this particular type of network design, due to the excessive number of computers and various branches throughout the WAN, the current speed will be quickly consumed by everyone in the infrastructure. . In addition, various types of advanced technologies will also be incorporated to this current design such as video and VOIP, all of which will require a much higher bandwidth.
Technical Goals of New Network Design

The technical goals of this project are, to increase security in each AD site, increase the speed WAN bandwidth and increase the speed of the LAN while implementing redundancy where ever possible in accordance to our budget and the company’s needs. Priorities are centered around network securities such as firewall implementation at each site and proper configuration of domain controllers, active directory and user accounts. Switches and routers will also require proper configuration for security enhancements. Afterwards, network performance requires enhancement, streamline and improved scalability. Performance is particularly important at the corporate office due to the fact that most data will be sent to the corporate office from the branch office and from the stores. High availability will be implemented via redundancy of network devices. The network failover solutions will respond quickly to minimize loss of funds and communication due to downtime. To aid in lowered administration of the network, network management tools will be installed throughout the WAN. Out dated technologies will be replaced to make way for more economical and productive technology solutions. Outdated equipment will be scrapped or donated depending on its condition.
Technical Goals will be handled as the following: 1. Performance will be increased on the LAN/WAN. 2. Security will be increased. All outbound and inbound traffic will be scanned or configured for pass-through on the interior and exterior of the network 3. Availability will be increased via redundancy of all infrastructure devices. 4. Manageability will be implemented so that a Network Administrator can access and manage the network from one central location.

Technical Constraints of New Network Design
Security and performance must coexist on today's network due to threats from the internet and to guarantee the desired level of productivity. Network administrators must implement a broader set of security features yet improve application performance to meet the needs of the organization. This introduces major challenges; the implementation of numerous security platforms increases network latency, interface management and troubleshooting complexity. Additionally, treating Internet security and performance as opposing functions eliminates any hope of diagnosing Internet data stream issues or correlating the events that impact security and performance (Cymphonix). Security is primarily a layered function that requires scanning on multiple levels. Several other UTM appliance vendors, including Internet Security Systems Inc. (ISS), Secure Computing Corp. and Symantec Corp., are equally blunt in saying customers could experience as much as a 50% performance loss in speed. "In general, it's more like 10%, but 50% is possible," says Mark Butler, director of product marketing at ISS, which offers three multifunction security appliances in its Proventia line.
Urgent technical problems that need to be addressed are as follows: 1. Firewall's need to be upgraded and redundancy needs to be configured incase the primary firewall experiences any downtime. 2. Routers need to be upgraded and require an internal firewall as a second layer of security. 3. Switch redundancy, security, and QoS will be configured in the Corporate office and the Branch offices. 4. Bandwidth Availability needs to be dramatically increased over the WAN and LAN. 5. Microsoft Exchange 2010 is required on the in Atlanta, the Headquarters office.

New network Design Analysis, Including Security
The new network design has been implemented to increase data throughput, set high availability within each location serviced and owned by the company and to increase security across the WAN and LAN. We will look at the overall design and its advantages, then look at the individual sites and outline the technologies implemented.
WAN Topology Overview
RTC-Group, Inc. owns property in Atlanta, Florida, New York and Canada. The Organization requires that the headquarters offices in Atlanta intercepts all customer transactions from the stores in New York and Canada but can also share and administer the branch office in Orlando. Our team decided to use T3 connections using Frame Relay to route traffic between the sites. Frame Relay is widely used in companies that span internationally. The advantages of Frame relay are: * Reduced internetworking cost (in both hardware and carrier tariffs) * Increased performance with reduced network complexity * Increased interoperability via international standards
Since RTC has companies outside the continental United States Frame Relay was an obvious choice. Standards across borders and at home are imperative to have to ensure data flow and communication. Below is an IP table for the Corporate office, Branch Office and stores. WAN IP's/29 subnet | | | | | | Retail Technologies, Atlanta | 172.31.194.235, .244, .250, .236, .245, .252 | | | | | Branch Office, Orlando | 172.31.194.248 | | | | | Duane Reade, New York | 172.31.194.233 | | | | | Peavey Mart, Canada | 172.31.194.241 | | | | |
New routers were implemented to better server security and redundancy throughout the WAN. Initially, the WAN was configured with only one router at each site in the company. This is called a single point of failure and it is strongly discouraged in all IT configurations. We remedied this problem by setting up router failover on all networks within the company. Moreover, these routers have special security features enabled to help block unwanted traffic to the network.
To ensure that customer information and transactions are held to the highest standards of privacy and security RTC decided to configure Site-to-Site VPN tunnels with IPSec from Duane Reade and Peavey Mart to RTC headquarters offices. After customers have completed a transaction with our stores our AS400 server stores the transaction in our database to help research what customers are buying and how often. This and other company data is imperative to keep secure at all times. These configurations are made possible with the Sonicwall Firewall at the corporate office. Its configured for failover and have over 4000 VPN licenses for scalability.
The new WAN design will provide more security and speed compared to the old network design. Key points for WAN Topology: * Security * Redundancy * Bandwidth

LAN Topology Overview
Atlanta Corporate Office
The Corporate office is the central point of data communication within the company. Most WAN/LAN traffic is accessing the servers at this location. Customer transactions, email, VOIP, database queries and the web server are all located in this environment which is why most of the cost and premium technology was implemented on this side of the WAN. Analysis of this LAN will be reviewed by applications, security, performance and switch configuration.
Initially, the corporate office did not have a secure infrastructure for data to pass through, central user management, email solutions or share policy's. The new design has implemented these crucial servers and services. * Microsoft Windows Server 2008 R2 Enterprise -Managed Domain * Microsoft Windows Exchange 2010 SP1-Viable Email Solution * Active directory services-Manage Users * SSL Certificate configuration on all Web Servers-To secure external communications. * Avaya-VOIP management console * Solar Winds Orion- Network Management and Network Monitoring * MMSXTrend- Database console for customer transaction logging * SharePoint 2010-File and application sharing/communication
Security has been increased from the implementation of several systems, Microsoft Active Directory services, Firewall settings, VLANs, and VPN settings to New York and Canada. Active directory and proper domain configuration helps with security because only authenticated users can access network resources. Firewall settings have been configured to block and accept particular traffic based on the companies needs. Here is a template of basic pass/block settings for your internet facing firewall from Cisco.com:
NAT Policies:

Additionally, any DMZ traffic should be blocked from accessing the internal network. VPN site-to-site will be configured using IPSec+GRE and WFQ. Some quality of service (QoS) techniques, such as weighted fair queuing (WFQ), perform conversation hashing decisions based on the original source and destination IP address, which can be ubiquified after IPSec or GRE encapsulation. While DiffServ markings are copied to the outer IP header in tunnel mode IPSec, the original source and destination are not carried forward into outer IP header (Cisco press.com) This VPN configuration ensures that all packets sent are encrypted and are not fragmented.

VLAN's have been configured to decrease broadcast domains within the LAN. This protects our network by only allowing certain traffic that is configured to access the switch network. All packets not configured with proper VLAN settings will be automatically dropped. VLAN configurations are highlighted below:

VLAN Number: | VLAN Name: | Configuration: | 100 | Retail | Fast Ethernet | 200 | Marketing | Fast Ethernet | 300 | IT Support | Fast Ethernet |

Performance has been increased greatly on the backbone of the network. Fiber is implemented from the servers to the core switches that service those servers. Speeds can reach up to 8GB per channel through the Cisco 9148 switch. This is an exponential increase of data throughput on the backbone with fiber configuration. The distribution and access layer switches are both configured for 1000MB transmission speeds. Between all three levels of switches are trunks, 802.1q for an even higher increase of data flow. See Trunk configuration below:

Switch Name | Tunneling w/ Trunk | VLAN | Cisco Fiber 9148-Core | 802.1q | 100,200,300 | Cisco 2048 Distribution SW | 802.1q | 100,200,300 | Cisco Catalyst WS-C3560E | 802.1q | 100,200,300 |

For failover, all switches are configured with their partner device which constantly monitors the primary switch for uptimes. Since VOIP is the primary mode of voice communication our team made several steps for optimization on the network. View these steps below: * Enable G.711 Codec * Configure QoS * Set the Qos bandwidth settings to 100 * Configure the Access Control List for Voice traffic * Set Qos Priority to Minimal-delay

LAN Topology Overview
Orlando Branch Office
The branch office has much lower overall network configuration than the corporate office. There is only one floor which is comprised of 50 users. Domain controllers are using Windows servers like in the corporate office. Microsoft offers features that can allow remote sites to share information in one site. This feature is used to access all the network data resources at the corporate office. Since this was such a small project we decided to cut cost where ever possible. On this side of the network, 2 switches that are configured for failover handle the roles of access, core and distribution layered switches. VOIP is configured and optimized for network traffic precedence. See configuration below: * Enable G.711 Codec * Configure QoS * Set the Qos bandwidth settings to 100 * Configure the Access Control List for Voice traffic
The firewall is able to protect the data that is being transmitted from the wireless devices on the network. Security for the wireless technology has been scrutinized thoroughly to ensure the best security offered. See configuration below: * Disable SSID broadcast * Enable MAC Address Filtering * Ensure password protection via ADES.

LAN Topology Overview
Stores: Duane Reade, New York and Peavey Mart, Canada
Duane Reade and Peavey Mart are stores that have the exact configurations. These sites are configured with extra security in mind due to the nature of business, point of sale. The network itself does not need to be very fast except for data transmission to the corporate office. Internet services connect via proxy server that are pointed to the corporate office as well as the ecommerce server database. If required these stores can access information in Atlanta through the VPN connection. The application server and the file server are all remotely administered from Atlanta.

Implementation Schedule
This system upgrade is estimated to be completed in 71 days. We will ensure our project manager will monitor the progress of this project and report to our lead IT manager. Below, we have listed all major milestones that accommodate the completion of this robust project. Each date as shown is an estimated approach and does not account for unforeseeable issues that may push the project beyond the scheduled completion date.

Testing of the New Network
Our initial tests will be deployed on a pilot system. We will maintain the right to minimize down time during this robust upgrade and a pilot system will certainly accomplish this goal. Your existing T1 link will continue to operate while the new T3 line is being configured and I would like to add, during this configuration, your redundant link, cable internet, will remain as your backup link in case something goes array. Once this T3 link is established and meshed, it will be tested for connectivity, delay, and security. We estimate these upgrades to take up to 71 days until completion. I am also noting, the Headquarters office will first be upgraded so that each branch remains and has at least, 99.99% availability.

Budget
Our total Budget for this new network implementation is approximately $302,694.28. Knowing that this may seem high for initial costs, we must first understand that security in a network is vital to the operational status that this organization must maintain. We deal with issues concerning sensitive information every day. Due to the lack of internal security, we see a clear upbringing to establish a much more secure network. Our budget brings into light a clear objective that we must secure our network all while increasing productivity within this organization. As noted below, we have developed a table illustrating the total costs in our corporate office in Atlanta, GA. Your return will only lead this company, RTC Inc., to secure its status as an application service provider leader among the point of sale market.

Conclusion
Since Retail Technologies Incorporated’s conception, we have witnessed a rapid growth both internally and externally. This includes providing support as well as multiple services to other organizations such as Duane Reade Corporation located in New York and Peavey Mart Stores, Inc. located in Canada. This sudden influx of added responsibility has certainly caused the IT department to take a closer look at our network as a whole. Our IT team took the preverbal magnifying glass and researched every inch of our companies network and the stores that we service. After doing so all networks spanning from southern Florida to New York and across continental lines, to Ontario Canada have been upgraded to more secure systems. Moreover, all networks have had a significant boost in performance and reliability. No one device failure can cause a network black out or data interruption because in every LAN at least one point of failure with its switch network, firewalls and routers. Bandwidth has been increased across the WAN from a T1 line to a T3. Also, a more robust and widely used routing protocol is being used for data security and flexibility, Point-to-Point Protocol. For this upgrade of the network, the ROI will be, an enhanced security and performance network that handles disasters in a much less costly manner. Through these upgrades RTC can continue to honor their mission statement: Provide and maintain service level agreement standards throughout our deep customer based relations. Customers are our success, and it is the customer whom we maintain our loyalty to by provide the skills and knowledge necessary to all who we may come in contact with.
