IETF WG
Path Computation Element (PCE) Working Group
Standards work centered on the path computation element architecture and related protocol mechanisms.
Open PCE working groupIETF Work
Standards leadership and RFC contributions remain a distinct part of the technical record.
The standards track stands alongside product, research, and publication work, with working-group leadership and RFC output across traffic engineering, PCE, MPLS, and low-power routing.
The emphasis here is on working groups, protocol architecture, and standards documents.
