In this paper I will be discussing the importance of communication protocol, the network architecture, traffic analysis and the overall network performance including latency, response time and jitter for Kudler Fine Foods.

The communications protocol explains and identifies rules for providing information via a network and constitutes a complete protocol series which represents the protocols used at the various levels of usage. A fascinating characteristic of communications protocols is that they can be placed over each other which means one may go over another. An example to show this feature is that HTTP can step or jump over TCP and IP which both are a part of the Internet Protocol Suite and also jump over IEEE 802.11 which belongs to the Ethernet Protocol Suite.

Communications protocols have several various properties such as using circuit mode or packet switching and connected or connectionless. By using communications people can communicate easily via email, phone, chat rooms, and video conferencing. Users may be permitted to share files and data with permission to access storage devices. Furthermore, computers may have access to other devices such as printers and faxes on the network in which to complete tasks. There are also disadvantages to consider such as computer hackers, viruses and worms connected to the networks. Another issue can be the complexity of the computer network with regards to set up and often a capital expense for a large company network.

Circuit switches and packet switches have typically held separate places in a company where circuit switched networks were employed for telephone calls while packet-switched networks managed data. The two different modules were low cost and efficient and were both used with the company for a long time. The hardware originally used for circuit-switched networks is the PBX system and the packet-switched networks utilize computer servers.

The updated circuit-switched networks an electronic signal goes through several switches before a connection is made. During this time no other traffic can use these switches. However, in the packet-switched network the messages are broken down into small packets that look for the most efficient route when a circuit is available although the packets do not need to follow the same path.

X.25 or frame relay. X.25 uses circuit switching while frame relay utilizes packet switching. While packet switches bundle data into smaller packets which is less expensive more phone and voice lines are circuit switching. Circuit switches are more reliable and a point to point connection yet more expensive. TheX.25 has quality service and less delivery error where frame relay was created to relay data as quickly as possible with lower number of high level procedures. A major difference is that the X.25 has the auto repeat request while frame relay must rely upon a higher protocol for resending a transmission. The x.25 is a part of
