...Network Design for Kudler Fine Foods Part 3 Network security is an ever more important part of network design, with everything moving toward being fully electronic and companies expanding their networks farther and farther away from their central hub (by the use of satellites) the chances and opportunities are going ever more present in today’s work place. Kudler fine Foods is making a huge leap forward with redesigning their entire network and by linking all three stores together through a central hub. This is a double edged sword in that this will make the stores more compactable with each other and this will expand there ability to retrieve accurate data from the servers on the fly but this also opens up Kudler Fine Foods to cyber attacks that they have not had to think about before. Hardware is a key component to securing a network. Kudler Fine Foods new network will have multiple hardware choices to make. Each location has Point of Sale (POS) computers that need to be secured from attack; there are office computers that will need to be secure. The POS server will need to be secured as well. There is the wireless Ethernet switch that will connect to the modem and Wide Area Network (WAN) between the three stores. The central hub location for the WAN (the Del Mar store) will also need to make sure the data servers are secured as well as everything else already mentioned. The desktop computers are going to be up to personal preference for Kudler Fine Foods, most desktops are...

...Router is small physical device that joins multiple networks together and operates at the network layer of the OSI model. A sophisticated small box-like pieces of equipment that multiple computers can connect to with each features a number of ports at the front or back that provide the connection points for these computers, a connection for electric power, and a number of LED lights to display device status. Though router and switches all share similar physical appearance, router differs substantially in their inner workings. A router is designed to join multiple area networks (LANs and WANs). On the Internet or on a large corporate network, it serves as intermediate destinations for network traffic. A router receives TCP/IP packets, checks it out to identify the source and target IP addresses, then forward the packet its intended destination. A router for home networks (called broadband) also can join multiple networks and designed specifically to join the home (LAN) to the Internet (WAN) for the purpose of Internet connection sharing. In addition, a broadband router contains several features beyond those of a traditional router. A broadband router provides DHCP server and proxy support and offers integrated firewalls. A wired Ethernet broadband router typically incorporates a built-in Ethernet switch that allows several hubs or switches to be connected to them, as a means to expand the local network to accommodate more Ethernet devices. A Network switch is a small hardware...

...closely to deliver a quality project on time for the company. We [must] keep in mind as well to meet some technical customer requirements, keep the network managed and running at its best performance, and ensure that the network is pretty secure. The design for this network begins by designing the local network, at each of the provided locations, and then connecting all the offices together in an effective Wide Area Network (WAN) Design. The network design will include both voice and data sharing. Microsoft Project will be used as a tool to organize and manage the complete project, and it will include budget and schedule. We also must remember that the main design centers are in San Francisco, Detroit, Paris, Tokyo, and Sao Paulo, with Corporate Headquarters lodged in San Francisco. The remaining offices are used as sales offices. Consider the company to operate on a 24 hours a day and 7 days a week basis, because it is global. It has been said, that with the advent of globalization, WAN has become a major artery for communication between remote offices and customers in any corner of the globe. Additionally, with data center consolidation, applications are moving to centralized data centers and clouds. We can also take advantage of virtualization within the centralized data center. WAN plays an even more critical role, because ABC survival is dependent on the availability and performance of the network. In the past...

...Introduction As a network consultant hired by Acme Manufacturing, the company has asked Team A to develop a new networking design for their expanding business. The description below describes the key steps involved in developing a WAN for Acme Manufacturing. The company has six different buildings in six different locations throughout the world which need to be networked collectively. All the remote locations need to be able to communicate effectively with the main headquarters which is located in Atlanta, Georgia. The two buildings which house the headquarters are located across the street from each other. One building is used solely for corporate operations while the other building is used for staffing the sales and engineering department. Network Topology The best choice for the company would be to use a LAN with routers and Ethernet cables. This is a logical choice because the speeds of the network will be far superior and will help to reduce the total cost of the network. The three distribution buildings are located in Chicago, Phoenix, and New York. It is not feasible to run cabling to theses locations due to cost, so using T3 leased lines to communicate is the recommended method to connect the buildings with headquarters. The plant facility building is located in China. Using satellites to communicate to the headquarters network will work best because of the large distance between the buildings. Using these recommendations will allow all the different buildings...

...A network switch is a small hardware device that joins multiple computers together within one local area network (LAN). Ethernet switch devices were commonly used on home networks before home routers became popular; broadband routers integrate Ethernet switches directly into the unit as one of their many functions. High-performance network switches are still widely used in corporate networks and data centers. Advantages Switches have increased available network bandwidth. There is reduced workload on individual computers. Increased network performance. There are fewer packet collisions. And some disadvantages are: They are significantly more expensive. Network problems can be difficult to trace through a switch. Broadcast traffic. Below is a diagram showing how switchg/hub are interconnected in a network A hub is a device for connecting machines into a network. It is a non-intelligent connection but tends to be very cheap. It allows all machines to send packets to every machine connected and wait for the required machine to reply. This causes delays as all the ports are used for every transmission. A network switch is the more recent method. This has intelligence and remembers which machines are connected to each port, so it passes any transmission straight to the correct port. This reduces collisions on the network when it is busy and is therefore much faster. It is more expensive, although nowadays there is very little difference in price. A repeater...

...NETWORKS AND TELECOMMUNICATONS A FULLY FUNCTIONAL NETWORK DESIGN FOR SHELLY FASHION PRESENTED BY: Osazuwa Olufemi George Business requirement Shelly fashion is a clothing boutique that sells clothes to both male and female customers. Their goal is to be the biggest retail clothing store in the country which aims to provide customers from the ages of 5 to 45 years of age a wide variety of quality clothing. The clothing retail store is open six days a week to customers who come in and buy their clothes directly at the store. The transaction is recorded and stored on the store’s computer with a Store Management Software which keeps track of inventory, sales, and computes the profits of the retail store biannually. Shelly fashion is looking to expand its reach using internet technology so it would be able to meet with the growing number of customers and also to connect all its other and future branches together to form a centralized network. With the network the retail store would be able to launch its home delivery option where customers would be able to buy clothes online and have their goods brought to them at their homes without having to be physically present at store. The business owners want to embark on a project to set up a telecommunications network which should be able to reach their business requirements. Shelly fashion’s business requirements for the proposed network are as follows: * Reduce operating cost by cutting cost too make telephone calls...

This design includes the infrastructure for the corporate headquarters located in San Francisco, as well as the other design centers in Detroit, Paris, Tokyo, and Sao Paulo. We then follow up by explaining the infrastructure of the sales offices, which may not require as high grade of equipment as the design centers depending on its requirements. Finishing with the overview of the entire wide area network, connecting each site to the corporate headquarters which is where we will begin our design. The corporate office being the main headquarters will include many services such as file, print, email, directory, and application. These services will be separated onto at least two different servers due to the constant strain we may see from directory and email services. If necessary we will implement an application server as well to run any in-house programs the company may be familiar with. We also suggest the use of a database server dedicated to storing and providing access to its information throughout the network, which...
