Perusing the 2.6.14 kernel changelog, ran across "DCCP." Hadn't heard of this before.

This sounds like a good thing for VOIP, especially on wireless networks. An attempt at a connection oriented datagram protocol.

I like this idea. Instead of everybody and their brother custom coding their own congestion workarounds into the apps, have it built into the protocol. Would make network troubleshooting a lot easier. Instead of having to understand each app's quirks, you know one common method.

I'd like to see a UDP vs. DCCP bakeoff. Maybe take Asterisk, VideoLan and Quake3 builds, one using UDP, the other DCCP, and run them through standardized network congestion scenarios. See how UDP vs. DCCP fares in each app.
