What is a protocol RFC?
A Request for Comments (RFC) is a formal document from the Internet Engineering Task Force ( IETF ) that is the result of committee drafting and subsequent review by interested parties. Some RFCs are informational in nature.
What is RFC in TCP IP?
RFC (stands for Request For Comments) is a document that describes the standards, protocols, and technologies of the Internet and TCP/IP. Since 1969, about 2400 Requests for Comments (RFCs) have been published on various networking protocols, procedures, applications, and concepts.
What RFC 2460?
RFC 2460 is the first document to lay out the basic design of the IPv6 protocol and resulting packet: the 128-bit address; the IPv6 packet, the fixed (40-byte) header, the various extension headers and formats for each (including the original effort to make IPv6 more secure with authentication and security extensions); …
What is RFC standard in networking?
In the computer network engineering and design realm, a Request for Comments (RFC) is a memorandum published by the Internet Engineering Task Force (IETF) describing methods, behaviors, research, or innovations applicable to the working of the Internet, along with Internet-connected systems.
What are RFCs used for?
Request for Comments (RFCs) are mainly used to develop a “standard” network protocol, a function of a network protocol or any feature which is related with network communication. RFCs (Request for Comments) are the basic building blocks of today’s modern computer networks and the internet.
How many RFCs are there?
8,500 RFCs
Today there are over 8,500 RFCs whose publication is managed through a formal process by the RFC Editor team.
Is RFC a standard?
The IETF adopts some of the proposals published as RFCs as Internet Standards. However, many RFCs are informational or experimental in nature and are not standards. The RFC system was invented by Steve Crocker in 1969 to help record unofficial notes on the development of ARPANET.
Why is RFC used?
What are the different categories of RFC?
In addition to standards-track documents (proposed, draft, standard and BCP), the RFC series contains three other categories: Informational, Experimental and Historic.
What is the minimum packet size in IPv6?
For IPv6 the minimum frame size is 84 bytes, since the IPv6 header is 40 bytes long.
What do RFC 349 and 1700 have in common?
5. What do RFC 349 and RFC 1700 have in common? Both RFC 349 and RFC 1700 have an assigned number and both have wide standard functions. They also offer applications that offer link, socket, port, and protocol.
Is the RTP protocol the same as RFC 1889?
The protocol supports the use of RTP-level translators and mixers. Most of the text in this memorandum is identical to RFC 1889 which it obsoletes. There are no changes in the packet formats on the wire, only changes to the rules and algorithms governing how the protocol is used.
How does the RTP Control Protocol ( RTCP ) work?
The RTP control protocol (RTCP) is based on the periodic transmission of control packets to all participants in the session, using the same distribution mechanism as the data packets. The underlying protocol MUST provide multiplexing of the data and control packets, for example using separate port numbers with UDP.
How does the Internet Protocol carry the data?
This protocol calls on local network protocols to carry the internet datagram to the next gateway or destination host. For example, a TCP module would call on the internet module to take a TCP segment (including the TCP header and user data) as the data portion of an internet datagram.
What does the reception report in RTCP mean?
For that purpose, each instance of the audio application in the conference periodically multicasts a reception report plus the name of its user on the RTCP (control) port. The reception report indicates how well the current speaker is being received and may be used to control adaptive encodings.
