Summary

Recommendation ITU-T Q.3302.1 specifies the resource connection initiation protocol (RCIP) for use to carry resource control requests and responses between transport resource control physical entities within the same domain. This protocol is designed to be able to support signalling along a chain of control elements in an operator's network for a collection of most commonly used QoS models and requirements, including (but not limited to) traffic specification, priority, multiprotocol label switching (MPLS) labels and virtual switching connection information. A multimedia service call traversing the network, which comprises one or more sessions (each having application/user-specific QoS specification), will get desired QoS treatment in the data plane (i.e., the chain of transport physical entities), through the appropriate configuration of the transport physical entities by the transport resource control physical entities.
