Appendix A. Comparison of Protocols

This appendix compares some of the well-known protocols that your router supports. It is provided as a memory aid and is not meant as a reference.

Protocol Comparison Table

The following table compares the protocols.

Table 76. Comparison Protocols

ISO OSI Model	TCP/IP	IPX	Other
7 Application 6 Presentation 5 Session	Telnet, FTP, TFTP, SGMP
4 Transport	TCP, UDP	PXP, SPX
3 Network	IP, RIP, BGP, ICMP	RIP, SAP

Key to Protocols

Table 77 is a key to the protocols.

Table 77. Protocol Key

Protocol	Description
BGP	Border Gateway Protocol. An IP external routing protocol.
FTP, TFTP	File Transfer Protocol; Trivial File Transfer Protocol.
ICMP	Internet Control Message Protocol. Used to send network level error and control messages between routers and hosts.
IP	Internet protocol. IP is a widely used standard transport protocol. IP is the 2210 routers' basic protocol. IP leaves some error-checking to higher-level (end-to-end) protocols.
IPX	Internet Packet Exchange Protocol.
RIP	Routing Information Protocol (Routing protocols are used to determine network topology and data paths). RIP is the most common IP routing protocol.
SGMP	Simple Gateway Monitoring Protocol. Used to obtain statistics in machine-readable form from 2210 routers.
SNMP	Simple Network Management Protocol. Used to obtain statistics in machine-readable form from 2210 routers.
TCP	Transport Control Protocol. An end-to-end (host-to-host) protocol that is often used with IP. Useful for sending streams of data. Uses checksums, acknowledgments, and timeouts to ensure the correct delivery and sequence of data.
