The IESG has received a request from the Bit Indexed Explicit Replication WG
(bier) to consider the following document: - 'BIER Penultimate Hop Popping'
<draft-ietf-bier-php-12.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
last-call@ietf.org mailing lists by 2024-10-10. Exceptionally, comments may
be sent to iesg@ietf.org instead. In either case, please retain the beginning
of the Subject line to allow automated sorting.

Abstract

This document specifies a mechanism for Penultimate Hop Popping (PHP)
in the Bit Index Explicit Replication (BIER) architecture. PHP
enables the removal of the BIER header by the penultimate router,
thereby reducing the processing burden on the final router in the
delivery path. This extension to BIER enhances operational
efficiency by optimizing packet forwarding in scenarios where the
final hop's capabilities or requirements necessitate such handling.
The document details the necessary extensions to the BIER
encapsulation and forwarding processes to support PHP, providing
guidance for implementation and deployment within BIER-enabled
networks.
