Hi, Following the ALTO meeting, there's a couple of things I would like to mention regarding ALTO home proxies (draft-picconi-alto-home-proxy-00).
1) I propose to mention home proxies in the ALTO discovery draft. If there is an ALTO server running at the home (e.g., on the gateway, on a NAS, etc.), it could be easily discovered through SLP/uPnP/Bonjour. This "local" discovery does not mean that the "traditional" discovery becomes useless: the client may want to determine what the "authoritative" ALTO server is, to check whether the "local" ALTO server is providing the data the client wants. However, discovering a local server is still useful, as the client may use it to keep ALTO queries local. 2) I plan to edit the ALTO home proxy draft to include the "HTTP redirect" use case, which I mentioned during the Paris meeting. The idea is that applications may discover a local ALTO server through SLP/uPnP/Bonjour, and this local server always redirects to the closest ALTO server. The advantage is that the client does not need to find the closest ALTO server: the local server does it for him. This scenario makes most sense when the ISP includes such a "redirecting ALTO server" in the home gateways that it ships to its users. Of course, if the home gateways have enough RAM, hard disk space, CPU, etc., the local server may cache the ALTO information and respond to local queries instead of redirecting them. Please let me know what you think. Best, Fabio
