The IESG has received a request from the Bit Indexed Explicit Replication WG (bier) to consider the following document: - 'Tree Engineering for Bit Index Explicit Replication (BIER-TE)' <draft-ietf-bier-te-arch-10.txt> as Proposed Standard
The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the [email protected] mailing lists by 2021-08-11. Exceptionally, comments may be sent to [email protected] instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This memo describes per-packet stateless strict and loose path steered replication and forwarding for Bit Index Explicit Replication packets (RFC8279). It is called BIER Tree Engineering (BIER-TE) and is intended to be used as the path steering mechanism for Traffic Engineering with BIER. BIER-TE introduces a new semantic for bit positions (BP) that indicate adjacencies, as opposed to BIER in which BPs indicate Bit- Forwarding Egress Routers (BFER). BIER-TE can leverage BIER forwarding engines with little changes. Co-existence of BIER and BIER-TE forwarding in the same domain is possible, for example by using separate BIER sub-domains (SDs). Except for the optional routed adjacencies, BIER-TE does not require a BIER routing underlay, and can therefore operate without depending on an Interior Gateway Routing protocol (IGP). As it operates on the same per-packet stateless forwarding principles, BIER-TE can also be a good fit to support multicast path steering in Segment Routing (SR) networks.
