P802.1CS – Link-local Registration Protocol

This standard specifies protocols, procedures, and managed objects for a Link-local Registration Protocol (LRP) to replicate a registration database from one end to the other of a point-to-point link and to replicate changes to parts of that database. A facility is provided to purge the replicated database if the source becomes unresponsive. LRP is optimized for databases on the order of 1 Mbyte.

Link-local Registration Protocol is designed to facilitate the creation of application protocols that distribute information through all or part of a network.

Current “802.1Q Multiple Registration Protocol (MRP)” is optimized for databases up to 1500 bytes, and slows significantly when used for larger databases. There is a need to overcome this limitation in an efficient manner.
