The most commonly used Internet protocols

RFC document #AbbreviationName Usage
[RFC768]UDPUser Datagram Protocol UDP is a protocol that provides simple, low-level tools for the transmission and reception of network packets directly to applications. UDP does not control the data transfer and is used mainly for watching or listening to multimedia files on-line.
[RFC791]IPInternet ProtocolIP is a routable network-level protocol used for unreliable communications of data from one network node to another. The network makes no guarantees about the packet and none, some, or all of the following may apply: data corruption; out of order communications; and/or lost, dropped or discarded communications.
[RFC792]ICMPInternet Control Message ProtocolICMP allows Internet nodes to report on errors or submit information on unusual operating conditions.
[RFC793]TCPTransmission Control ProtocolTCP is the main traffic protocol that ensures reliable delivery of information.
[RFC823]GGPGateway to Gateway ProtocolGGP is a protocol two gateways use to interact with each another, specifically in executing control tasks.
[RFC826]ARPAddress Resolution ProtocolARP is the method for finding a host's hardware address when only its network layer address is known. It is primarily used to translate IP addresses to MAC addresses.
[RFC854]TELNETTelecommunications Network ProtocolTELNET is a network-level protocol to remotely access a computer by means of a command line interpreter.
[RFC894]Ethernet   Ethernet is a technology for organizing a LAN, where all hosts can receive all messages.
[RFC959]FTPFile Transfer ProtocolFTP is an Internet service for transferring files from one computer to another. It enables connecting to FTP servers, viewing file directories on those servers, uploading files to the server or downloading files from the server, transferring files between servers, etc.
[RFC1034], [RFC1035]DNSDomain Name SystemDNS is a system that translates human-recognizable domain names and computer hostnames into computer-usable IP addresses (and vice versa) over TCP/IP.
[RFC1112]IGMPInternet Group Management ProtocolIGMP is a communications protocol used to manage a membership of IP multicast groups. It is used by IP hosts and adjacent multicast routers to establish multicast group memberships.
[RFC1350]TFTPTrivial File Transfer ProtocolTFTP is mainly used for the start up of computers that do not have any data storage devices. Unlike FTP, it does not include possibilities for authentication (although IP address filtering is possible) and is based on UDP.
[RFC1738]URLUniform Resource LocatorURL is used to specify the addresses of almost all network resources.
[RFC1905], [RFC1907]SNMPSimple Network Management ProtocolSNMP provides management and control of network devices and applications. Each network agent (device or app) reports through SNMP its status and what factors can be controlled from an administrator?s workstation.
[RFC1939]POP3Post Office ProtocolPOP3 is an application layer Internet protocol for retrieving e-mail from a remote server over a TCP/IP connection and is usually used along with SMTP.
[RFC2131]DHCPDynamic Host Configuration ProtocolDHCP is a network level protocol that enables computer devices to automatically obtain IP addresses and other parameters necessary for working with TCP/IP connections.
[RFC2616]HTTPHyperText Transfer ProtocolHTTP is an application layer Internet protocol for transmitting mainly web pages (text documents in HTML format) and any images and files connected with those web pages.
[RFC2637]PPTPPoint-to-Point Tunneling ProtocolPPTP is a technology that provides very secure Internet communications, which cannot be line tapped.
[RFC2821], [RFC2822]SMTPSimple Mail Transfer ProtocolSMTP is a network level protocol for transmitting e-mail messages over a TCP/IP connection.
[RFC3501]IMAPInternet Message Access ProtocolIMAP is an application layer Internet protocol that enables a local client to access e-mail on a remote server. It is used to both send and retrieve e-mail messages.
   SSLSecure Sockets LayerSSL is a cryptographic protocol, which provides secure communications over the Internet between a client and server.
