Hi, Speaking as co-chair of CATS.
The CATS working group is still not ready for any protocol solutions work, although we are aware that a number of proposals have been made. At the moment we are still developing the architecture, requirements, and metrics. These are fundamentals that we need to resolve before it is appropriate to get behind any protocol solutions. However, it is worth noting that CATS is an edge function. That is, it does traffic steering not routing/forwarding within the network. One of the issues to be resolved is how to get the right compute metric information to the right places in the network without challenging other places to handle unwanted information. In this context, many might apply caution to the use of an IGP because of the load it places on every node in the network even though most of those nodes do not need to see the compute traffic. It might be worrying that this load would compromise convergence for the "Normal business" of the IGP - namely to forward packets. It might be useful to look at the work done long ago in the L1VPN working group to use a separate instance of the IGP (in that case, the work was only done for OSPF) to distribute VPN membership information between remote peers at the edge of the network. This approach protects transit routers from the additional information and makes it just an edge function. See RFC 5252 and RFC 5523.
