LSR experts,

We have revised the draft-dunbar-lsr-5g-edge-compute to address the comments and feedback from IETF 112.
https://datatracker.ietf.org/doc/draft-dunbar-lsr-5g-edge-compute/

In a nutshell, the proposed solution

  *   advertises the "Site-Cost" via IP prefix reachability TLV associated with the (anycast) prefix
The  Site-Cost is the aggregated cost associated with an Edge Compute (EC) server (i.e., ANYCAST prefix), computed based on the IP layer related metrics for the prefix, such as Load Measurement, the Capacity Index, the Preference Index, and other constraints by a consistent algorithm across all egress routers to which the EC servers are attached.


  *   Uses a Flag in the Flexible Algorithm TLV to indicate that  "site-cost" needs to be included for the constrained SPF to reach the Prefix


Any feedbacks? Or suggestions?

Thank you very much
Linda
