Abstract
This paper describes the basic concepts of point-to-multipoint (p2mp) path computation on the basis of the Path Computation Element Metric Protocol (PCEMP). PCEMP, being soft-memory based, has the capability of dynamic configuration of its finite state machines (FSMs) in the participating PCEMP peers, and thus can support a wide variety of traffic engineering techniques that are needed to guarantee bandwidth demand and scalable fast protection and restoration in PCE based p2mp frameworks ensuring end-to-end QoS support. The authors have proposed this concept in the newly constituted PCE WG (Path Computation Element Work Group) in the RTG sub-area of the IETF. In this research-in-progress paper, we show how PCEMP as it is defined, and the optimal number of PCE Domain Areas (PCEDAs) that might be allocated to a PCE node for the best performance in end-to-end QoS management based on a tight optimal Cramer Rao bound for the state machine executions.
