CrossBow prototype available

Wouldn't that be cool: Being able to divide your physical Network Interface Card (NIC) into several virtual interface cards and having the ability to prioritize networking traffic and having full control over which service gets how much? - Stop dreaming! This vision has just become reality: My team just showed me a demo today that they have prepared for the SunLabs OpenHouse tomorrow: The demo is showing a client and a server both running Solaris. User 1 is running within a Solaris Container on the client and is receiving a video clip from the server. The quality of the video is very good because the client has enough networking bandwidth available. Then user 2 who is running out of a different container on that client is trying to do an ftp download from the server and eats up a lot of the networking bandwidth - the video comes to a grinding halt. But now we turn on CrossBow's networking bandwidth control, create a virtual NIC that is dedicated to the container who is downloading the video. To User 1 this now looks like having a dedicated physical machine with a dedicated NIC - pretty cool. And even better, CrossBow has implemented the resource control in the kernel itself, so there is no performance penalty when you run it - this could really change the way people in the data center think about networking bandwidth control today. For more details check out the project web site on OpenSolaris: http://www.opensolaris.org/os/project/crossbow/ Markus

Hey Markus, This sounds like fun. I would like to read more about the same. Is there a way I can access the website? I tried but it says "resource not found". Tnanks, Sonali
