Protocol Review of Telephone and Data Networks

In our initial analysis, Riordan's network architecture is primarily based on Ethernet technology. Other technologies also discovered were VoIP, satellite and public switched telecommunications networks. With regards to these technologies, further analysis identified protocols that are used in conjunction with these technologies. These protocols are primarily contained in the Internet protocol suite.

The Internet protocol suite is a highly related collection of protocols. It is also commonly referred to as TCP/IP. TCP and IP were the first and primary protocols developed for internetworking. However, it is comprised of many other protocols that collaborate with each other to perform each distinct task required for communication on and to other network components. Based on the network topology and devices that reside on the network, the protocols that will be discussed are IMCP, TCP, IP, UDP, DNS, FTP, HTTP, IMAP4, POP3, SIP, SMTP, SNMP, SSH, and Rlogin. These protocols are integral to Ethernet networks; some are required, some optional, and some to be avoided but replaced with better solutions.

The Internet Control Message Protocol (ICMP) is a network layer protocol. "It is one of the core protocols of the Internet protocol suite." IMCP is primarily used in reporting network errors on the network commonly seen when pinging or using trace routes when trouble shooting connectivity.

Transport Control protocol (TCP) is the interface between the application layer and the network layer. TCP provides a reliable connect between the applications and the network. Conversely, UDP does not provide a reliable connection. It sends packets without regards to delivery or sequence. However the advantage of UDP is that it is fast. "While the total amount of UDP...
