Question

Care super insurance company has 150 computers that are networked together. It also has four servers and uses a star topology wired network to reach employees' offices, with a bus interconnecting four floors in its office building. Because of a staggering influx of Internet business, the network administrator's task is to boost network performance and availability as much as
possible. The company also wants a network design that's easy to reconfigure and change because workgroups form and disband frequently and their membership changes regularly. All computers must share sensitive data and control access to customer files and databases. Aside from customer information and billing databases, which run on all servers, employees' desktop computers must run standard word-processing and spreadsheet programs.
Use the following write-on lines to evaluate the requirements for this network. After you finish, determine the best network topology or topology combination for the company. On a blank piece of paper, sketch the network design you think best suits company needs. Remember: High performance and easy reconfiguration are your primary design goals!
a. Design a Network topology for the given scenario.
b. Will the network be peer-to-peer or server based? Justify your answer.
c. Analyse business goals for this network.
d. Analyse business priorities for this network.
e. Investigate business constraints for this network.

Answer 1

Solution 1: Since in this case, the network admin has the task to design the network in such a way so that it is easy to implement as well it is also not very complex so that it can be modified at any point in time and can be extended or degraded this property automatically requires it to be robust and flexible enough. So keeping all these points in mind a tree topology or star-bus topology would be the most suitable network topology in this case as it is highly robust and fault tolerant and it can be conveniently extended or degraded whenever needed.

Solution 2: It has to be a server server-based network as it is easy to monitor and administer. The server-based entwork also allow the users to share the resources efficiently which would be a problem in case of a peer-to-peer network.

Solution 3: The business goals for this network are:

1. Providing the required bandwidth to the users for the proper functioning of the work.
2. Ensuring the information security as well as the data privacy to the users over the network.
3. Ensuring the availablity of the resources at all the times to its users.

Solution 4: The thing that should be at the priority for the network system is that the system should not fail to function as it is a part of the critical infrastructure to the organization. It must be able to serve the people of the organization at all times.

Solution 5: The business constraints to this network are:

1. It must be able to provide a particular amount of bandwidth to its users over the communication channel.
2. The network should have least latency so that it is highly responsive and allows the users to work without any hassle.
