Hi, There are some concerns after I skimmed over the draft. How many SIMPLE servers should be deployed in a metro network? If SIMPLE servers are stateless, would anycast address be used for avalability and load-balancing? How does the ISP provision the IP address and port of SIMPLE servers to the hosts behind the IPv4-only CPEs? If SIMPLE servers are stateless, I assume the multicast capability would be absent, right?
