TCP/IP Protocol Family
The TCP/IP family consists of the following protocols:
Link layer:
-
ARP: Address Resolution Protocol: Map IP to hardware (e.g. Ethernet) addresses
-
RARP: Reverse ARP: Map hardware (e.g. Ethernet) to IP addresses
Link layer (serial line):
-
CSLIP: Compressed Serial Line IP: Compressing TCP/IP Headers for Low-Speed Serial Links (RFC 1144), obsolete
-
PPP: The Point-to-Point Protocol
-
PPP-MP: The Point-to-Point Multilink Protocol
-
SLIP: Serial Line IP: Transmission of IP datagrams over serial lines (RFC 1055), obsolete
Network layer:
-
IP: Internet Protocol (version 4): transfer IP packets from one host to another. One of the most common protocols today. This is what the Internet is built around.
-
IPv6: Internet Protocol (version 6): transfer IP packets from one host to another
-
ICMP: Internet Control Message Protocol (version 4): This is a protocol to report common errors and events in the IP, TCP and UDP protocols.
-
ICMPv6: Internet Control Message Protocol (version 6): This is a protocol to report common errors and events in the IPv6, TCP and UDP protocols.
-
IGMP: IP multicasting
Network layer (routing):
-
BGP: Border Gateway Protocol
-
EGP: Exterior Gateway Protocol
-
GGP: Gateway to Gateway Protocol
-
IGRP: Interior Gateway Routing Protocol
-
ND: Neighbor Discovery
-
OSPF: Open Shortest Path First
-
RIP: Routing Information Protocol
-
RIPng: Routing Information Protocol next generation
-
DSR: Dynamic Source Routing (Ad-hoc protocol)
Network Layer (IPsec Internet Protocol Security):
Transport layer:
-
These protocols run atop IP:
-
DCCP: Datagram Congestion Control Protocol: stream based, reliable, connection oriented transfer of data
-
SCTP: datagram (packet) based, reliable, connection oriented transfer of data
-
UDP: User Datagram Protocol: datagram (packet) based, unreliable, connectionless transfer of data
-
UDP-Lite: Lightweight User Datagram Protocol: datagram (packet) based, unreliable, connectionless transfer of data
-
TCP: Transmission Control Protocol: stream based, reliable, connection oriented transfer of data
-
PortReference: TCP/UDP port numbers ThTextese protocols run atop UDP, and provide additional transport-layer services:
-
RTP: datagram (packet) based, unreliable, connection oriented transfer of time sensitive data
-
RTCP: RTP's control protocol
Session layer:
-
NetBIOS: an API and several protocols providing various networking services.
-
NetDump: a simple protocol for capturing crashed operating system memory cores over a network
-
DCE/RPC: Remote procedure calls using the OSF's RPC mechanism
-
HTTP: Hyper Text Transfer Protocol: (and other files as well). Probably the best known protocol as it is used to allow users surfing on the Internet.
-
SMTP: Simple Mail Transfer Protocol: send mails to a mail server
Presentation layer:
Application layer:
-
ANCP: Access Node Control Protocol: TCP based L2 control protocol used in service provider DSL and PON Networks.
-
DHCP: Dynamic Host Configuration Protocol: distribute IP, Gateway and DNS server addresses and alike
-
DNS: Domain Name System: translate human readable addresses (e.g. wiki.wireshark.org) into IP addresses
-
FTP: File Transfer Protocol: file transfer (unsecure)
-
IMAP: retrieve mails from a mail server
-
iWARP-DDP: Direct Data Placement (part of the iWARP protocol stack)
-
iWARP-MPA: Marker PDU Aligned Framing: adaptation layer between TCP and DDP (part of the iWARP protocol stack)
-
iWARP-RDMAP: Remote Direct Memory Access Protocol (part of the iWARP protocol stack)
-
NNTP: Network News Transfer Protocol: news transfer
-
NTP: Network Time Protocol: sychronize time between hosts
-
PANA: Protocol for Carrying Authentication for Network Access: user authentication for network access
-
POP: Post Office Protocol: receive mails from a mail server
-
RADIUS: remote user authentication and accounting
-
RLogin: remote login: remote shell access (unsecure)
-
RSH: Remote SHell: remote shell access (unsecure)
-
RSIP: Realm Specific IP (RFC 3102-3104)
-
SSH: Secure SHell: encrypted remote shell access
-
SNMP: Simple Network Management Protocol: network management (RFC 1157,1901-10,2271-75)
-
Telnet: remote shell access (unsecure) (RFC 854,855,1700)
-
TFTP: Trivial File Transfer
-
SASP: Server/Application State Protocol (RFC 4678)
