Switching & Routing The purpose of this paper is to provide a better understanding of routing and switching used in a network environment and also familiarize the reader with various hardware and software connected with there works. This paper will look at some shifting concepts that will include store and forward switching, cut through shifting, fragment free switching, and V-Lan. This paper will also cover routing theories, along with a few comparisons such as routed vs. routing protocols, Classful vs. classless protocols, and distance vector vs. link state protocols. Switching The definition of a change or network switch is a little device that joins multiple computers together, working on layer two of the OSI, to form a local area network or LAN. Network switches are also known as smart hubs. Rather than only dispersing the data evenly over a network that the switch really inspects the data packets for destination info, and then forwards the data to a particular location. By forwarding the information to its intended location bandwidth over the network is much better regulated (Mitchell, 1999). Store-and-Forward switching refers to a switching method that, after inspection, stores data packets for delivery. The data is received from the sender and passes a cyclic redundancy check together with a check to be sure it fits the required size limitations. After inspection and the check for errors the data is stored or held in physical storage until network availability allows the data to be sent to its destination (Cisco Systems, 2008). Cut-through switching is a method of switching which uses only the destination information to switch data packets to a particular destination or destination segment. Although previous store-and-forward...
