Abstract
Where the payload of a pseudowire comprises a number of distinctflows, it can be desirable to carry those flows over the Equal CostMultiple Paths (ECMPs) that exist in the packet switched network.Most forwarding engines are able to generate a hash of the MPLS labelstack and use this mechanism to balance MPLS flows over ECMPs.
This document describes a method of identifying the flows, or flowgroups, within pseudowires such that Label Switching Routers canbalance flows at a finer granularity than individual pseudowires.The mechanism uses an additional label in the MPLS label stack. [STANDARDS-TRACK]
