Dear WG, We have just submitted a new version of draft-ietf-spring-srv6-srh-compression.
Based on the feedback and suggestions from WG participants and implementers, this revision clarifies the SR Source Node (Sec. 7) and Control Plane (Sec. 9) requirements for the SIDs defined in this document. The changes are as follows. - Section 7 (SR Source Node) - Added a set of rules for the SR source node to validate the SIDs of this document before using them in a segment list (new Sec. 7.1), following off-list comments from implementers. - Clarified that the compression algorithm described in this section may apply to any segment list that contains at least one of the SIDs of this document, following off-list comments from implementers. The algorithm compresses the eligible SIDs of the uncompressed segment list, while the remaining non-eligible SIDs are left uncompressed in the result segment list. - Added a method to determine the C-SID length of REPLACE-C-SID flavor SIDs, which is needed for the compression, following co-author reviews. - Section 9 (Control Plane) - Clarified that the SR endpoint nodes must advertise the SIDs of this document in their control-plane protocols with an argument value of 0 and a SID structure matching the SID format on the SR endpoint node, following off-list questions from implementers. - Other changes - Clarified in Sec. 4.2.7 the encoding of Arg.FE2 argument for End.DT2M behavior with the REPLACE-C-SID flavor, following co-author reviews. - Added in Sec. 13 a new implementation report and references to recent interoperability testings. - A few editorial changes.
