Abstract:

   [RFC8584] defines Highest Random Weight (HRW) as the algorithm for
   Designated Forwarder election in EVPN, and, in Section 3.1, names
   the Consistent Hashing family of algorithms as addressing the same
   object-to-server mapping problem before explicitly declining to
   evaluate them: "these will not be considered here."
   [I-D.ietf-bess-evpn-per-mcast-flow-df-election] subsequently
   introduces a scope transition, from per-(ES,VLAN) to per-
   (ES,VLAN,S,G) election, that is precisely a key-space-resizing
   event of the kind Consistent Hashing was designed to bound churn
   for. This document proposes the applicability analysis RFC 8584
   declined to make: it defines a DF-churn metric, states HRW's and
   Consistent Hashing's known theoretical guarantees against it, and
   sets out an evaluation methodology, using bounded-load Consistent
   Hashing as the specific comparison point, given multicast group
   popularity is known to be highly non-uniform in deployed networks.
