Xiaohu, few comments:
RFC7311 is very specific about containing routes with AIGP attribute within AIGP administrative domain, while not well defined in RFC7311, perhaps worth saying something? The value field of the AIGP TLV in RFC7311 is 8 octets long - draft defines 4 octet value, I assume you are following RFC8570 and RFC7471 encoding? Rather that making AIGP TLV and NETWORK_LATENCY TLV mutually exclusive, perhaps defining how they interact, if both are present would be a better choice? Capability Advertisement - 3rd para doesn’t parse, be clear if it applies to labelled routes only (RFC7311 is vague here - "tunneling of some sort”) Manipulation of the Unidirectional Link delay sub-TLV in IGP’s could natively be done by using Unidirectional Link Delay TLV in RFC8571. 3107 has been obsoleted by 8277 Cheers, Jeff On Oct 15, 2019, 11:57 AM +0200, 徐小虎(义先) <[email protected]>, wrote: > > Hi all, > > I just recently realized that the performance routing mechanism as described > in this draft could facilitate the deployment of segment routing across > multiple ASes of an administrative entity where low-latency SR paths across > ASes are needed for carrying latency-sensitive and high-priority traffic.
