Please Whitelist This Site?

I know everyone hates ads. But please understand that I am providing premium content for free that takes hundreds of hours of time to research and write. I don't want to go to a pay-only model like some sites, but when more and more people block ads, I end up working for free. And I have a family to support, just like you. :)

If you like The TCP/IP Guide, please consider the download version. It's priced very economically and you can read all of it in a convenient format without ads.

If you want to use this site for free, I'd be grateful if you could add the site to the whitelist for Adblock. To do so, just open the Adblock menu and select "Disable on tcpipguide.com". Or go to the Tools menu and select "Adblock Plus Preferences...". Then click "Add Filter..." at the bottom, and add this string: "@@||tcpipguide.com^$document". Then just click OK.

Thanks for your understanding!

Sincerely, Charles Kozierok

(Page 4 of 4)

Application Layer (OSI Layer 5/6/7) Protocols

As discussed in the topic on the TCP/IP model, in TCP/IP the single application layer covers the equivalent of OSI layers 5, 6 and 7. The application protocols covered in this Guide are shown in Table 23.


Table 23: TCP/IP Protocols: Application Layer (OSI Layer 5/6/7)

Protocol Name

Protocol Abbr.

Description

Domain Name System

DNS

Provides the ability to refer to IP devices using names instead of just numerical IP addresses. Allows machines to resolve these names into their corresponding IP addresses.

Network File System

NFS

Allows files to be shared seamlessly across TCP/IP networks.

Bootstrap Protocol

BOOTP

Developed to address some of the issues with RARP and used in a similar manner: to allow the configuration of a TCP/IP device at startup. Generally superseded by DHCP.

Dynamic Host
Configuration Protocol

DHCP

A complete protocol for configuring TCP/IP devices and managing IP addresses. The successor to RARP and BOOTP, it includes numerous features and capabilities.

Simple Network Management Protocol

SNMP

A full-featured protocol for remote management of networks and devices.

Remote Monitoring

RMON

A diagnostic “protocol” (really a part of SNMP) used for remote monitoring of network devices.

File Transfer Protocol, Trivial File Transfer Protocol

FTP, TFTP

Protocols designed to permit the transfer of all types of files from one device to another.

RFC 822, Multipurpose Internet Mail Extensions, Simple Mail Transfer Protocol, Post Office Protocol, Internet Message Access Protocol

RFC 822, MIME, SMTP, POP, IMAP

Protocols that define the formatting, delivery and storage of electronic mail messages on TCP/IP networks.

Network News Transfer Protocol

NNTP

Enables the operation of the Usenet online community by transferring Usenet news messages between hosts.

Hypertext Transfer Protocol

HTTP

Transfers hypertext documents between hosts; implements the World Wide Web.

Gopher Protocol

Gopher

An older document retrieval protocol, now largely replaced by the World Wide Web.

Telnet Protocol

Telnet

Allows a user on one machine to establish a remote terminal session on another.

Berkeley “r” Commands

Permit commands and operations on one machine to be performed on another.

Internet Relay Chat

IRC

Allows real-time chat between TCP/IP users.

Administration and Troubleshooting Utilities and Protocols

A collection of software tools that allows administrators to manage, configure and troubleshoot TCP/IP internetworks.
