Abstract:

   With Segment Routing (SR) architecture, a unicast flow can be source-
   routed through an SR network following an explicit path specified in
   the packet, without the need for per-flow state in the network.  As a
   result, the protocols that would be otherwise needed to signal the
   per-flow unicast state are not needed either.  In the case of
   multicast, traffic can be either source-routed or non-source-routed,
   and this document summarizes options for non-source-routed multicast
   in an SR network, including pre-SR tree-based multicast technologies,
   BIER, and various SR specific solutions.  The pros and cons of each
   solution are listed for considerations by operators and vendors, with
   regard to the principle and characteristic of SR as mentioned above.
