What are the other well-known standard protocols in the TCP/IP family?
Other than TCP and IP, the three main protocols in the TCP/IP suite are the Simple Mail Transfer Protocol (SMTP) [8], the File Transfer Protocol (FTP) [3], and the TELNET Protocol [9]. There are many other protocols in use on the Internet. The Internet Architecture Board (IAB) regularly publishes an RFC [2] that describes the state of standardization of the various Internet protocols.
