Networking Concepts – Summary

The alma of this paper Is to find the easiest and cost-effective method of connecting two separate networks. A relatively simple device called a bridge, which Is implemented through a combination of hardware and software, achieves interconnection between two networks that are the same. Interconnection between networks that are not similar, for example, a Wide Area Network and a Local Area Network can be achieved through as much more complex device called a router.A router Is a device, which can accept messages that are in a certain format produced by one particular network and reinstates them to another format that is used by another network. In this particular case of Nancy, a director of network infrastructure, it is not likely that a full replacement of networking equipment Is required. Alternative A, which is about Installing a few devices In the headquarters of BOB. The advantages of this alternative are that is that It Is the easiest, the least expensive and the quickest to imp lement.The other advantage is that this approach will have a very small impact on the network infrastructure. The disadvantage of this approach is that there will be performance penalties due to lack of integration in the architecture of the network. The second option Is replacing the network components of Bob's entire network for It to use the same protocols as BE and the two can communicate freely. The advantage of this approach Is that there will be a huge Improvement In performance due to integration in the network architecture.The major cons of this alternative are that there will be major impacts on the network infrastructure; there also will be ajar costs incurred and a lot of time required to implement this alternative. Their last alternative Is whereby the management of BE bank replaces all the devices of the B WAN and even probably the MANS so that each city or branch can communicate with the network of BE while the Lana in individual divisions remain unchanged. The advant age of this alternative is that there will be better performance gains than in alternative A and takes significantly little time to implement.The con of this approach is that it does not achieve full integration of the network and the stickiest to support Bobs network over time It might add problems to the My recommendation is that alternative C is the most applicable when it comes to the time taken to implement and the cost that is incurred in order to achieve a significant level of network architecture. However, when it comes to a long-term point of view, the second alternative is the best so long as BE passes through a transition stage like the first alternative in order to meet its immediate needs and take ample time to put into action the full changes of the infrastructure.
