The core purpose of this report is to evaluate the nature of the network infrastructure that existed before at Computer Dynamics in relation to the objectives of the organization and put down necessary strategies to improve the network infrastructure in order to achieve the maximum functioning of the system.
Computer Dynamics is a well based software company . the company has a network that existed before and the network is currently housing three hundred computers in two different buildings. Though the network was upgraded to a latter network infrastructure, the company as now grown because of good marketing of the company.
In the previous network, there was no network connection between the two buildings, also the current network has problems due to high rates of overloading of data caused by a higher number of users and many other reasons of overloading. In any case this network is not upgraded to a better and latest network technologies, the problem might persist because more projects are expected in the coming days.
From the problems that the association phases it has decided to change the layout of the network structure. Cisco has been given the task to investigate and come up with a network layout that will be used to upgrade the network structure in the company.
In generally the structure of the network in the company is mentioned in relation to the goal of the business for the network. In addition, an analysis regarding the user requirements and the network that is currently existing in the organization is critically performed . the main areas that are covered in this report includes according to Agata(2012):
The layout of the proposed network is stated within the report and is aimed at serving the company for 3-5 years maintaining its high capacity. Circuitry includes connection of infrastructure, Hardware/Devices , Software ,Network Architecture.
This part explains the users has part of the networking plan. This are the clients and administration managers who will be using and controlling the network . It also explains the type of applications that the user will use to access the network and make any father changes in the network. The user type using the network can be called network traffic level which can be either high or standard.

In both buildings the presence of the of layer 2 switch simply show the impacts on the user especially in building two I causes slowness in communication and performance among the users. This because more of the users compete for the bandwidth from the server making it have a slow response. Users in building two requiring the service of building one have to wait for the response due to slow response from the servers from the building. This may be due limited bandwidth or low communication of the devices in the network. Many computer in the network causes high utilization .
In terms of operating system windows 2003 and 2004 have been superseded by the current operating system due to compatibility issue in which the programs need new versions of the operating system.
As from the diagram the network is out of date. The amount of heavy applications used by programmers, graphics designers and web developers is straining the entire network. The joining of the roles of the servers in building one was all meant save space and minimizing the cost of installing the networks by purchasing many servers. However has network is growing the compatibility is the issue in the network where is experiencing slowness in performance.
Star topology is implemented in the system in the network at each c connecting centre i. e three computers are connected to the switch layer. Switch layer are connected to each other and then finally connected to the data centre which provides or serves information to the switches which in turn distributes to the computers. The data centers are connect together to each other. Meaning any failure of one data centre or switch layer may lead to total failure of the all system since one depends on the other .The connection also leads to delay in data transfer since no routing hence there is only one way of data to be transferred from one point to another hence low rate of data transfer due to colliding in the cables.
Since the existing network of the Computer Dynamics company is not working full to their required standards .The company needs a network design that is faster ,secure and efficient in distribution of information around the company.
A layer of a network which is physical is required to interconnect the networks between the buildings .This promotes resource sharing and data communication between the buildings Opennhammer(2009) .
The network will run in Cat 6 cable has in the current network. The two buildings will be connected with optic fiber cable since the buildings are 40 meters apart cable of 50 meters is required. The optic fiber cable will enable network resource sharing between the two buildings is increased high speed.
The current layer 2 of the existing network will be replaced with layer 3 both in accessed layer and distribution network.
Layer 3 switches with 24 and more ports will be used. The cable will be used in communication among the switches since they a have great speed in transfer of data. Two end servers will be required in server virtualization and data recovery. An additional server required in transfer of data and more switches specified ones are.
memory size will be 500 GB Storage capacity: 64 Bit Operating System .For each server in the network.
Introduction of layer three will improve high rate of transfer of data and e many switches will enable more users to connect to the network.
The clients applications that are up to date will not be changed. However other software that are inadequate can be can be replaced with cloud based software best is cheap and easily available.
The license fee implementation cost.
Due to high cost of licensing the softwares, the softwares between the two buildings will be integrated together to reduce the total expenditure.
Windows XPO
Linux operating system.
The network will use the 3 layer switch structure which it will be connected with many other devices to promote interconnections between the buildings. The following is an example of the proposed network layout of the two buildings Yoshida (2009) .

Conclusion
From the above research, the following are the findings;
The overall performance of the network is very poor, this is because the utilization of this particular network is actually very high which in turn causes errors in application. Since the company is using applications that are so heavy, this cannot be suited in a network with poor performance which might hinder the growth of the company.
From the background, it is noted that there is no network connection in between the two buildings that the company is using. This has forced the company to share data through VPN which is a site to site tunnel. This tunnel is not sufficient because effort is replicated and data too in every building. This same tunnel gives out limited bandwidth. The compatibility of some software in the company are problematic.
The following measures therefore are recommended that the company should embrace;
