RPCP Resource Pool Control Protocol
draft-mahajan-rpcp-protocol-00

Abstract

RPCP is a generic interface protocol between two entities, where one entity acting as Resource Pool (RP) and other being the Resource Pool Controller (RPC). The RP entity in turn may be acting as RPC for other RPs in a hierarchical manner. The resource being defined can be any hardware/software, physical/virtual resource. In today's telecommunication world, the intelligence is being moved away from the hardware (the embedded platform) or the switching fabric to a more generic computing resource (high-end servers). These computing resources controls the call logic, service logic and the network signalling part. This implies that there is a need for an open interface protocol by which call agents or signalling agents can control this rather dumb hardware as resource pools. This helps in easy and smooth integration of these entities even if they come from different vendors. The Interworking and Gateway market is a very big market today. The network architecture proposed for these solutions carries the intelligence away from the resource pools (also called media gateways) to call agents or pool controllers (also called media gateway controllers). With such network architectures the need for such a protocol is more prominent. There are many other needs and use of such a protocol which will be discussed in detail in this white paper. This paper does not try to define the complete protocol, however the basic definition and the protocol architecture will be defined. The document first describes the application of Resource Pool Control protocol, followed by requirements from this Protocol and then defines the Protocol Architecture with basic protocol definition. The annexure of the document gives few examples on RPCP usage.
