Hi WG, I reviewed the draft, and support the adoption. The proposal may be a useful improvement of SR architecture, and it will be valuable to consider it.
The follows are my comments: - Regarding scalability, it will depend on how to design configurations, and I think that there is little difference between existing technologies and the proposal. The number of virtual networks which can be built will strongly depend on the spec/ability of the underlay network. For example, the number of available QoS classes is limited by the number of queues which routers have. Or the size of a forwarding table depends on performance of TCAM. I think a critical point on scalability is underlay network spec/ability rather than the nature of techniques/protocols. - Simplifying data plane structure and its management by unifying several forwarding mechanisms to SID may be one of advantages of the proposal. - This extension may be a fundamental improvement, and it may not be necessary to be tied to usage for enhanced VPN solution.
