Abstract
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.
