Hi, Zhenqiang:

Thanks for your support.
Before we proposed and designed the solution that described in" rel="nofollow">, and also the PCEP extension that described this WGLC document, we have analyzed the characteristics and challenges of SRv6 based solutions.
As indicated in" rel="nofollow">, we are trying to find the solution that can meet the following requirements:

  • Same solution for native IPv4 and IPv6 traffic.
  • Support for intra-domain and inter-domain scenarios.
  • Achieve E2E traffic assurance, with determined QoS behavior, for traffic requiring a service assurance (prioritized traffic).
  • No changes in a router's forwarding behavior.
  • Based on centralized control through a distributed network control plane.
  • Support different network requirements such as high traffic volume and prefix scaling.
  • Ability to adjust the optimal path dynamically upon the changes of network status. No need for reserving resources for physical links in advance.

Hi All,

I support it, I have read the latest version and it is ready for publication in my opinion. Scenarios to be addressed is described in" class="cite xref" rel="nofollow">RFC8735. Based on the progress of SRv6, I think SRv6 is an alternative solution.

Best Regards,
Zhenqiang Li
