ITU-T Recommendations

Recommendation ITU-T X.609.6 specifies signalling requirements for content distribution services over a managed peer-to-peer (P2P) overlay network that is specified in Recommendation ITU-T X.609. Content distribution over a managed P2P network provides flexible content management over existing overlay networks and also enables contents providers to control accessing of the overlay network. That is, the content provider can update the content to be distributed over an overlay network anytime and every update will be applied to all peers in the overlay network. This Recommendation lists requirements for the related reference points that are defined in Recommendation ITU-T X.609 for providing content distribution services and it also describes high-level procedures for a content distribution service over managed P2P architecture and roles of the managed P2P components for the service.
