Most forwarding engines are able to generate a hash of the MPLS label stack and use this mechanism to balance MPLS flows over ECMPs. This document describes a method of identifying the flows, or flow groups, within pseudowires such that Label Switching Routers can balance flows at a finer granularity than individual pseudowires. The mechanism uses an additional label in the MPLS label stack. {[}STANDARDS-TRACK{]}}, }
