Hi,

My feeling after this presentation is that, if we replace the PID with explicit IP prefix in the cost map of the current ALTO protocol draft(may need additional filtering function defined in the new version), we can get the similar result with H12 protocol. The difference is that in H12, the server ranks the IP prefixes for the requester, while in ALTO protocol draft, it gives the "cost" between them.

Are there any other differences I missed? Does H12 need to consider NAT(esp. carrier grade NAT) problem? I just try to understand more about it.

Thanks,
Haibin
