Hi,
Here are some clarification questions about the flex-algo draft.
1. As described in section 5, in path computation for a flex-algorithm, the node firstly needs to prune the links not included for this flex-algorithm, then run SPF or other algorithm within the pruned topology. If a node supports multiple algorithms, does this mean the node needs to maintain multiple pruned topologies?
2. If one path computed in algorithm-1 with latency metric and another path computed in algorithm-2 with bandwidth metric traverse the same link(s) in the network, can the latency or bandwidth SLA be guaranteed for the service? Or the path may need to be re-computed and adjusted to another link to avoid potential performance degradation?

主题: [Lsr] LSR Working Group Adoption Poll for Flex Algorithm Drafts

This begins a two-week adoption poll for the following Flex Algorithm drafts:

https://datatracker.ietf.org/doc/draft-hegdeppsenak-isis-sr-flex-algo/
https://datatracker.ietf.org/doc/draft-ppsenak-ospf-sr-flex-algo/

The adoption poll will end at 12:00 AM EST on May 2nd, 2018. Please indicate your support of opposition of the drafts.

Additionally, the authors are amenable to combining the drafts into a single draft. If you have an opinion, please state that as well.

Thanks,
Acee
