Rizzo, M. Handley, J. Crowcroft Status: Informational Date: December 2002 Mailbox: email@example.com, firstname.lastname@example.org, email@example.com, firstname.lastname@example.org, email@example.com, Jon.Crowcroft@cl.cam.ac.uk Pages: 18 Characters: 46853 Updates/Obsoletes/See Also: None I-D Tag: draft-ietf-rmt-info-fec-03.txt URL: ftp://ftp.rfc-editor.org/in-notes/rfc3453.txt This memo describes the use of Forward Error Correction (FEC) codes to efficiently provide and/or augment reliability for one-to-many reliable data transport using IP multicast. One of the key properties of FEC codes in this context is the ability to use the same packets containing FEC data to simultaneously repair different packet loss patterns at multiple receivers. Different classes of FEC codes and some of their basic properties are described and terminology relevant to implementing FEC in a reliable multicast protocol is introduced. Examples are provided of possible abstract formats for packets carrying FEC. This document is a product of the Reliable Multicast Transport Working Group of the IETF.
