Running head: NETWORK DESIGN NETWORK DESIGN 6 Network Design Student Name Course 2 July 2014 Professor Identify hardware and software needed to secure your choice of networks against all electronic threats. A network that helps a workstation to connect with each other is called a Networking hardware. If a company uses both routers and firewall, the company is assured protection of both wireless and cabled networks that are used in the company. Network hardware is suitable in any organization in the keeping of the organizations network safe. In the software part I will choose to use McAfee Anti-virus security software. This software in conjunction with firewall is a sure way of protecting a company. Routers when used along with hardware are the best security hardware needed if the company needs to increase the security of their network to a level where none of the intruders can be
- 2. able to access it (Radu, 2002). The function of the firewall in an organization is to ensure that all unwanted activities are blocked including hackers that can retrieve important and delicate information of the company. Hacking will be a very dangerous exercise where criminal can access the important information that a company has and use this information in blackmailing the company and its customers. Networking software’s also plays a major role in securing an organizations network security. The software has the capabilities of detecting viruses that may attack an organization and make an organization loose its critical information. McAfee is one of the top manufactures in ensuring that network security is maintained. The virus apart from detecting viruses, it is able to use internet firewall and detect any malware that an organization may be suffering from. It is true that an organization must have both hardware and software to ensure that they secure their information from hackers and viruses. Distinguish between local area networks (LANs), wide area networks (WANs), and wireless technologies. A local area network is a network that has a shared group of computers and the distance between the computers is generally small. The computers within this distance share the same network, this helps the Local area network to easily share printers and do exchange of files within the same facility or network. When Local areas network is connected to other networks and also other local networks, they can turn to be called Wide Area network. Local area networks are connected using Ethernet cables, adapters and also hubs. Wide area networks (WAN) are very different from the LAN. The internet is an example of a wide area network because it usually links computers that are outside the local area network and all over the world (Zhang, 2010). The internet is considered the most popular wide area network. When on has a personal computer that is connected to the internet he/she is using wide area network. Personal computers can also connect to local area
- 3. network and also metro area network. WAN is more expensive than the LAN because it uses leased lines in transmitting the network to users. Wireless local area network is a connected local area network but without a cable and wires. The condition of a local area network not using a cable in connection makes it a WLAN. Some of the advantages that are associated with the wireless local network is that they have low installation costs because they do not use wires during transmission. The wireless local network are also very mobile as compared to Wide area network and the local area network (Rainer & Cegielski, 2010). Wireless local area network can only be connected by the use of Wireless Access Point (WAP) which is transmitted by radio waves over a long area connected by the internet hub. The difference between the local area network and the wireless local area network is that the wireless local area network runs on IEE 802.11 standard. Wi-Fi connection is shared amongst people in buildings and those that live together in a neighborhood. It is the cheapest of all networks as it can be transmitted without costs. It has some disadvantages of delaying video calls and it is highly susceptible to security risks. Explain the concepts and building blocks of today’s data communication networks, such as switches, routers, and cabling. A network router is a more refined device as compared to the network switch or the network hub. Routers are typically very small in size just as switches and the hubs. They are shaped in a box-like shape, many computers can connect through them. The routers has features on the front and the back where one can establish connections from. They also have a connection to electric power and many a number of LED lights that blink whenever it is turned on. All of the three, routers, switches and hubs have the same physical appearance. Apart from the physical appearances routers have different inner functions (FitzGerald & Dennis, 2009). Traditional routers all have connections from where the local area network can be connected from. Routers are majorly used as intermediate destinations in

A network switch is a device that serves as a controller that enables network devices to talk to each other efficiently. This helps the businesses money and also increases employee’s productivity. Switches are responsible for creating a network while a router is responsible in the connection of the network for users to be able to share to the network. Self-assess your work against the Peer Evaluation Rating Scale In the part of team involvement, the student is very active and very substantive in team discussions.

NETWORK DESIGN 2 1 Networking Design 2 3 Network Design 2 Student Course name 25 June 2014 Professor Introduction: Protocols can be defined as rules that govern communication between many computers. This paper will analyze the advantages of protocols in an organization. It will also provide
- 6. solutions to the organization to prevent the organization from making losses from consuming large bytes of bundles. Importance of communication protocols Protocols have a major role in communication in the world. They ensure that there is communication between computers. Some of the common communication protocols that have enabled communication between computers include: HTTP- this communication protocol helps us to view pages that are kept in a different computer. FTP- this communication protocol helps us send or receive files from other computers that are connected by the protocol. SMTP/POP3 is communication protocols that help in sending and receiving of emails. Identify the protocols in your design and provide rationale for your decision According to the definition of protocol, there is links of communication in the given designs. Some of the protocols in the design include the corporate head quarter because it uses hypertext transfer protocol in viewing files that are contained in other computers that are stationed in other stations. The computers are interconnected by the internet. The information that headquarter can access from the other computers include information of the employees from customer plastic parts plant, plastic fan plant and the plastic beverage container plant. Another protocol s in the design is the plants because they can send and receive files by the use of file transfer protocol in receiving and sending information from the headquarters. Define the overall network architecture Network architecture is an organization’s computer framework that is complete. The diagram shows the network architecture of Riordan Manufacturing (McCabe, 2010). The network in this organization shows a detailed view of all the resources that can be accessed in the organization. The resources that can be accessed here include the all the plants that are under the corporate headquarter. Explain the usefulness of a traffic analysis
- 7. Some of the major benefits traffic analysis is to prevent those people in an organization tend to use more bandwidth making a loss to the organization. By observing the IP address of the HTTP requests, there is a possibility of you finding out the most sites that employees in an organization visit and therefore prevent them. Another usefulness of using traffic analysis is ensuring network security by preventing anomalies in the usage of bandwidth in the organization (Garber & Hoel, 2014). Traffic analysis also helps to know the level of links and therefore plan to get extra links that may reduce congestion. Explain the terms latency, response time, and jitter, and describe their effect on overall network performance and on the performance of your chosen organization’s network. Latency is the amount that a packet takes to be transmitted from one end to another across a network. Response time is the total time that a service takes to respond to a request and jitter is used to refer variations that occur in the arrival rate of packets under the same data flow (Weinstein, 2007). An abnormal jitter values can have a negative effect on real-time applications like videos. It is important to assess the delay time and jitter because it helps to determine if the voice application works. In an organization it is these terms will enable the organization to evaluate whether all the voice application is working, of they also help the organization to aid in the correct design and configuration of traffic prioritization. Explain the effect of data rates on each part of the network. Data transfer rate is the amount of digital data that is moved from one place to another in a specific time (SINGH, 2011.). Increase of data rates increases the throughput of the transmitted power. Increase in the data transfer rate means that information is transferred very quickly, therefore the higher the bandwidth of a given path, it means that the rate of transfer is high. Describe strategies to ensure the availability of network access in switched and routed networks. Some of the strategies that ensure that there is availability of
- 8. network access in switched and routed networks include redundancy, high availability, virtualization, planned outages and disaster recover. All this strategies are very vital in ensuring that an organization is having a good design of their backup solutions that the organization can count on and those that are cost effective to the organization. Risk analysis also is an important exercise to an organization because it evaluates the organizations profits or losses. Virtualization helps an organization to reduce power consumption and therefore they reduce the costs the organization is spending on the enormous power bills. Virtualization is also beneficial in providing high availability for critical applications and rationalizes application migration (Bauer & Adams, 2012). Virtualization can also simplify IT operation and also allow IT organization to change to faster business demands.

He also took a lead in establishing and following the goals and responsibilities of the team. He also has professional communication in interacting with other members of the team
