Hi, Just a note to say that we have made an update to the "Challenges in Routing" draft that was presented in RTGWG at IETF-113.
Asides from the usual editorial nits, we have picked up Jeff Haas' comments suggesting the inclusion of "the facility for extensibility" as a research question and a desirable outcome. As always, comments, thoughts, and reviews are very much welcomed.

Name: draft-king-irtf-challenges-in-routing Revision: 08 Title: Challenges for the Internet Routing Systems Introduced by Semantic Routing Document date: 2022-04-25 Group: Individual Submission Pages: 17 URL: https://www.ietf.org/archive/id/draft-king-irtf-challenges-in-routing-08.txt Status: https://datatracker.ietf.org/doc/draft-king-irtf-challenges-in-routing/ Htmlized: https://datatracker.ietf.org/doc/html/draft-king-irtf-challenges-in-routing Diff: https://www.ietf.org/rfcdiff?url2=draft-king-irtf-challenges-in-routing-08 Abstract: Historically, the meaning of an IP address has been to identify an interface on a network device. Routing protocols were developed based on the assumption that a destination address had this semantic. Over time, routing decisions have been enhanced to determine paths on which packets could be forwarded according to additional information carried principally within the packet headers, and dependent on policy coded in, configured at, or signaled to the routers. Many proposals have been made to add semantics to IP packets by placing additional information into existing fields, by adding semantics to IP addresses, or by adding fields to the packets. The intent is always to facilitate routing decisions based on these additional semantics in order to provide differentiated paths to enable forwarding of different packet flows on paths that may be distinct from those derived by shortest path first or path vector routing. We call this approach "Semantic Routing". This document describes the challenges to the existing routing system that are introduced by Semantic Routing. It then summarizes the opportunities for research into new or modified routing and forwarding approaches that make use of additional semantics. This document is presented as a study to support further research into clarifying and understanding the issues. It does not pass comment on the advisability or practicality of any of the proposals and does not define any technical solutions.
