Dear Paul,
Just to add some information. Vuze (formerly called Azureus) is one of the most popular BT clients. I assume that users using Vuze is a part of the BT community that you are referring to. Please correct me if I misunderstand here. Vuze is also a member of P4P. They are working pretty actively lately to improve both network efficiency and application performance. For example, their most recent release adds features to try to use network information through a network coordinate system. We are also preparing to launch a client-based plugin for Vuze to utilize P4P information (one of the ALTO framework). The objective of the plugin is that, through this plugin, either tracker-based or trackerless swarms will be able to start to use network information. We hope that this will be a good starting point to start to have affects on the large amount of P2P traffic that you are referring to, if I understand you correctly. There are sure other BT clients/trackers that we need to work on to better move the tide, and to maximize effects, we need to enter through both trackers and clients. But I do believe that ALTO can make a difference here. Maybe I am too optimistic here...The P4P WG participation includes many major p2p networks, including Pando, BitTorrent, Solid State, Grid Networks, LimeWire, Abacast, Azureus, Joost, etc.Just to be clear here, "BitTorrent" in your list is a single BitTorrent tracker which happens to be run by BitTorrent.com. It is not representative of the BitTorrent communities of which I spoke, namely the ones that are inundating ISPs.

The summary is that in exactly the scenario you assert that ALTO "does nothing" P4P (think of it as pre-ALTO) provide huge performance and efficiency benefits.That is quite possibly true; it is also not relevant to what I said. I was speaking about the BitTorrent communities that are currently the bandwidth problem for ISPs; you are speaking about other p2p communities whose current bandwidth usage is probably at least an order of magnitude less than the ones of which I am speaking. Of course, in the future, the bandwidth market may shift towards the kinds of systems you are talking about. If so, Alto could very well be helpful. People clearly want to work on that future problem, and Alto might be a good place to do it. My expressly-stated concern was that the problem statement document has wording that makes it sound like the Alto proposals might have an affect on the current large amount of traffic, which I believe it won't. <rest of information about Pando and P4P elided> --Paul Hoffman, Director --VPN Consortium _______________________________________________ alto mailing list alto at ietf.org https://www.ietf.org/mailman/listinfo/alto
