There are many things to consider when designing a computer network –such as costs of components, software and labor; communication, cohesion, expandability and many others. However, the end goal in such an enterprise is to have a fully functional, harmonious, and cohesive tiered system where duties and actions are divided, and delineated accordingly. One of the major network architectures used to facilitate this process is known as the TCP/IP Protocol Suite.

The TCP/IP Protocol Suite was designed by scientists in the effort to support a new type of network known as the ARAPNET that was being installed across the US in the late 60’s to 70’s. (White, 2013, p. 15) The challenge was to create an open system whereby all networks could freely communicate with each other. The design was based on a layered system whereby the user would connect at the topmost (or application) layer, while at the same time being removed or separated from the lower (physical) layer. Although the number of layers is not exactly set, depending on the source this number can range between five and seven layers, with each layer providing services to the layer above it. For the purposes of this discussion however, we will address the five layer model. The five layers of the TCP/IP Protocol Suite are: Application, Transport, Network, Network Access (or Data Link), and Physical. (White, 2013, p. 15) Application This layer supports all of the applications on the network. Some of the most frequent…
