The IESG has approved the following document: - 'Bit Index Explicit Replication (BIER) Ping and Trace' (draft-ietf-bier-ping-29.txt) as Proposed Standard
This document is the product of the Bit Indexed Explicit Replication Working Group. The IESG contact persons are Gunter Van de Velde, Jim Guichard and Ketan Talaulikar. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-bier-ping/ Technical Summary Bit Index Explicit Replication (BIER) is an architecture that provides optimal multicast forwarding through a "BIER domain" without requiring intermediate routers to maintain any multicast-related per- flow state. BIER also does not require any explicit tree-building protocol for its operation. A multicast data packet enters a BIER domain at a "Bit-Forwarding Ingress Router" (BFIR), and leaves the BIER domain at one or more "Bit-Forwarding Egress Routers" (BFERs). The BFIR router adds a BIER header to the packet. The BIER header contains a bit-string in which each bit represents exactly one BFER to forward the packet to. The set of BFERs to which the multicast packet needs to be forwarded is expressed by setting the bits that correspond to those routers in the BIER header. This document describes the mechanism and basic BIER OAM packet format that can be used to perform failure detection and isolation on the BIER data plane. Working Group Summary Was there anything in the WG process that is worth noting? For example, was there controversy about particular points or were there decisions where the consensus was particularly rough? Document Quality Are there existing implementations of the protocol? Have a significant number of vendors indicated their plan to implement the specification? Are there any reviewers that merit special mention as having done a thorough review, e.g., one that resulted in important changes or a conclusion that the document had no substantive issues? If there was a MIB Doctor, Media Type, or other Expert Review, what was its course (briefly)? In the case of a Media Type Review, on what date was the request posted? Yes, some part of it has been implemented by vendors who support BIER in some form. Personnel The Document Shepherd for this document is Mankamana Prasad Mishra. The Responsible Area Director is Gunter Van de Velde. IANA Note WG authors need to respond to the IANA review questions _______________________________________________ IETF-Announce mailing list -- [email protected] To unsubscribe send an email to [email protected]
