Dear SPRING WG, We have submitted a new revision of draft-filsfils-spring-path-tracing.
The previous revisions of the draft defined an SRH TLV and an IPv6 Hop-by-Hop Option for Path Tracing. Based on received feedback we have replaced the SRH TLV with an IPv6 Destination Option. The draft was last presented at IETF 113. The Hop-by-Hop option has running-code across 5 different ASICs from different vendors (all implementations are at linerate); in addition to the FD.io VPP and Linux Kernel opensource implementations. More info in Section 5 of the draft. We look forward to the WG review and feedback.

Name: draft-filsfils-spring-path-tracing Revision: 05 Title: Path Tracing in SRv6 networks Date: 2023-10-23 Group: Individual Submission Pages: 18 URL: https://www.ietf.org/archive/id/draft-filsfils-spring-path-tracing-05.txt Status: https://datatracker.ietf.org/doc/draft-filsfils-spring-path-tracing/ HTMLized: https://datatracker.ietf.org/doc/html/draft-filsfils-spring-path-tracing Diff: https://author-tools.ietf.org/iddiff?url2=draft-filsfils-spring-path-tracing-05 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
