Hi, All: Again, I support part of this draft be adopted.
The deployment of Flex-Algo should be separated from the SR-TE Policy. Then the use-case 1, 3 in section 3 should be pulled out, this can keep the original design principle of Flex-Algo. Adjacency-SID will only be included in the data packet when the packets need pass a TI-LFA path, which is described in case-2 of section 3. And, I saw there was contentions for the following paragraph in section 5: "The endpoint of a link shared by multiple flex-algo plane can reserve different queue resources for different algorithms locally, and perform priority based queue scheduling and traffic shaping. This algorithm related reserved information can be advertised to other nodes in the network through some mechanism, therefore it has an impact on the constraint based path calculation of the flex-algo plane. How to allocate algorithm related resouce and advertise it in the network is out the scope of this document." Since Flex-Algo doesn't consider the resource reservation, then such reservation information needs not be advertised out of the node itself for Flex-algo calculation. The local behavior based on the flex-algo related Adjacency-SID can be described if the authors prefer. SR-TE and Flex-Algo both can achieve the same goal, we need not mix them together.
