Dear SPRING WG, IPPM WG, We have submitted a new I-D for Path Tracing in SRv6 networks (https://datatracker.ietf.org/doc/html/draft-filsfils-spring-path-tracing) to SPRING WG.
We are looking for your feedback and comments. Path Tracing provides a record of the packet path as a sequence of interface ids. In addition, it provides a record of end-to-end delay, per-hop delay, and load on each egress interface along the packet delivery path to facilitate operation of SR networks. Path Tracing allows to trace 14 hops with only a 40-octet IPv6 Hop-by-Hop extension header. We will present Path Tracing to the SPRING WG at next IETF (https://datatracker.ietf.org/meeting/113/materials/agenda-113-spring-00.txt) Thanks, Ahmed From: internet-dra...@ietf.org <internet-dra...@ietf.org> Date: Friday, 4 March 2022 at 16:48 To: Ahmed Abdelsalam (ahabdels) <ahabd...@cisco.com>, cf(mailer list) <c...@cisco.com>, Mark Yufit <mark.yu...@broadcom.com>, Pablo Camarillo (pcamaril) <pcama...@cisco.com>, Pablo Camarillo (pcamaril) <pcama...@cisco.com>, Satoru Matsushima <satoru.matsush...@g.softbank.co.jp>, Thomas.Graf <thomas.g...@swisscom.com>, Yuanchao Su <yitai....@alibaba-inc.com> Subject: New Version Notification for draft-filsfils-spring-path-tracing-00.txt A new version of I-D, draft-filsfils-spring-path-tracing-00.txt has been successfully submitted by Pablo Camarillo Garvia and posted to the IETF repository. Name: draft-filsfils-spring-path-tracing Revision: 00 Title: Path Tracing in SRv6 networks Document date: 2022-03-04 Group: Individual Submission Pages: 15 URL: https://www.ietf.org/archive/id/draft-filsfils-spring-path-tracing-00.txt Status: https://datatracker.ietf.org/doc/draft-filsfils-spring-path-tracing/ Htmlized: https://datatracker.ietf.org/doc/html/draft-filsfils-spring-path-tracing Abstract: Path Tracing provides a record of the packet path as a sequence of interface ids. In addition, it provides a record of end-to-end delay, per-hop delay, and load on each egress interface along the packet delivery path. Path Tracing allows to trace 14 hops with only a 40-bytes IPv6 Hop- by-Hop extension header. Path Tracing supports fine grained timestamp. It has been designed for linerate hardware implementation in the base pipeline. The IETF Secretariat
