Hi Haibin, With VPN tunnels between IDCs, and there may be room for VPN-based relay cases for inter-IDC traffic optimization. E.g. congestion or failure on backhaul core. Therefore, I don’t see the need of retricting the relay routing to using direct routing method only.

But if you can give use cases that require VPN tunnel based relays, I can also update the document to support them.

And I have a quick question: by relay-based routing, do you mean relaying through direct routing or relaying through VPN tunneling?

It can help applications to find the optimal path between two endpoints, by asking ALTO server for the cost values of various paths between two endpoints, for example, VPN tunnel, direct routing, and through different relay nodes. We hope people who are interested can give their comments.

Filename: draft-song-alto-overlay-routing Revision: 00 Title: ALTO Protocol Extension For Overlay Routing Creation date: 2013-10-21 Group: Individual Submission Number of pages: 10 URL: http://www.ietf.org/internet-drafts/draft-song-alto-overlay-routing-00.txt Status: http://datatracker.ietf.org/doc/draft-song-alto-overlay-routing Htmlized: http://tools.ietf.org/html/draft-song-alto-overlay-routing-00 Abstract: This document describes an ALTO protocol extension for overlay routing. It considers three different methods to route traffic from a data source to a data receiver, which are direct Internet routing, VPN tunnel, and overlay routing via intermediate/relay node(s), analyze their use cases in real world and then proposes an extension to ALTO protocol so as to support a ALTO client to get cost value between hosts via these different routing methods. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
