Technical Summary
This document updates RFC 5440 (Path Computation Element (PCE) Communication Protocol (PCEP)) with some additional rules about the semantics and format of the Include Route Object (IRO). Specifically:
- The IRO is now to be regarded as an ordered list (previously this was left to the interpretation of the implementation).
- The IRO subobjects gain an extra bit to indicate whether they are strict or loose hops.
Working Group Summary
A survey was done of the PCE working group to determine how current implementations interpret the IRO. There were 9 respondents to the survey, which represents a good cross-section of PCEP implementers. The survey results were published in [I-D.dhody-pce-iro-survey]. The results were not unanimous, but it was clear that the majority of implementations would either be unaffected, or not significantly affected, by the change in semantics and format that are proposed in this draft.
Document Quality
At the time of the survey, there were already 5 implementations that conformed to the updates specified by this draft. Several other implementers have indicated that they plan to update their implementations to be in line with this draft. There have been no MIB doctor, Media Type or other expert reviews done.
