Robert,
Many thx for sharing this proposal. Three easy questions ..
Thanks for your comments
1. Do you envision that IP:PORT pairs would be manually configured by the operator ?
This is typically what sysadmins do when they configure web servers or other types of servers, they indicate in the configuration the addresses and port the server listens to. On a multihomed server, they either indicate they the server should listen to all interfaces or a subset of them. This configuration already exist.
2. Do you envision that such addresses may span multiple servers ?
Anycast setting is a load balancing problem that is the target for QUIC's preferred address transport parameter
3. Isn't this a bit overlapping (or to say stronger replacing) function of load balancers ?
The problem is different. A load balancer is typically a single address served by a large number of servers. This is currently the main use case for QUIC. This is discussed in https://datatracker.ietf.org/doc/html/draft-ietf-quic-load-balancers
In the draft, we focus on isolated servers. These could be web servers in companies or or example file servers that are running SMB over QUIC
Best regards, Olivier
