Summary

Recommendation ITU-T X.609.2 specifies the overlay resource control protocol (ORCP) that runs on the interface between a cache server/relay server (CS/RS) and an overlay management server (OMS), and on the interface between an OMS and a peer. The ORCP is used to reserve resources and to control the use of a CS and RS. Recommendation ITU-T X.609.2 provides the requirements, protocol operations and message formats used in each operation of the ORCP.
