Wired reports that Comcast finally provided information on its network management practices late Friday. In a report to the FCC (PDF), the cable company admitted to targeting P2P protocols Ares, BitTorrent, eDonkey, FasTrack, and Gnutella. Quoting: "For each of the managed P2P protocols, the [Sandvine Policy Traffic Switch] monitors and identifies the number of simultaneous unidirectional uploads that are passed from the [Cable Modem Termination System] to the upstream router. Because of the prevalence of P2P traffic on the upstream portion of our network, the number of simultaneous unidirectional upload sessions of any particular P2P protocol at any given time serves as a useful proxy for determining the level of overall network congestion. For each of the protocols, a session threshold is in place that is intended to provide for equivalently fair access between the protocols, but still mitigate the likelihood of congestion that could cause service degradation for our customers."

Danny Rathjens writes "In the continuing trend of big companies buying out small companies with open source products, Cisco has announced that they are buying Jabber. The press release doesn't really talk about the open source aspect of Jabber, and Jabber's website doesn't mention the news yet. I'm sure the question many of us have is whether Jabber's open source status will be changed in any way due to the purchase." Reader Eddytorial had this to contribute: "eWEEK offers a good look into how Jabber's messaging client will fit into Cisco Systems' overall 'presence' strategy in its market wars with Avaya, Microsoft, Nortel, and others. Cisco, which already had a basic instant messaging option, but one that didn't scale for an enterprise nearly as well as Jabber's, has just about everything else in place." It's also worth noting that Cisco open-sourced Etch in recent months.
