Standardization and publications

Standardization activities


In parallel, we are actively participating to IETF standardization activities for the codes as well as the associated protocols and applications:

  • RMT (Reliable Multicast Transport)
  • FECFRAME (FEC Framework) :

This is a major asset since it warrants a high level of maturity to some code specifications, it enables interoperable implementations, and it specifies all the details for their use in actual use-cases (currently with both file distribution and real-time streaming applications).

Important publications


V. Roca, C. Neumann, D. Furodet, "Low Density Parity Check (LDPC) Staircase and Triangle Forward Error Correction (FEC) Schemes", IETF RMT Working Group, RFC 5170 (Standards Track/Proposed Standard), June 2008.

This IETF standard describes the LDPC-staircase codes and their application to file transfer applications. A subset of this RFC is implemented in the OpenFEC library.

J. Lacan, V. Roca, J. Peltotalo, S. Peltotalo, "Reed Solomon Error Correction Scheme", IETF RMT Working Group, Request for Comments, RFC 5510 ("Standards Track/Proposed Standard"), April 2009

This IETF standard describes the Reed-Solomon codes and their application to file transfer applications. This RFC is implemented in the OpenFEC library.
