Status update for WG

The PCE working group is responsible for the Path Communication Element Communication Protocol (PCEP).  PCEP allows a Path Computation Client (PCC - for example, a head-end router) to request paths from, or have paths created by, a Path Computation Server (PCE).

The WG is discussing various enhancements to the stateful PCE. PCE is actively being used for computing and programing of segment routed (SR) paths. There are new proposals for use of PCE for Bit Indexed Explicit Replication (BIER) networks. Further, PCE is a core component of Software Defined Networking (SDN) systems. PCE WG has been working towards enhancing PCEP as an SDN southbound interface (SBI).
