Due to the nature of the TC system in linux, it could be used to satisfy your needs. Since any BW based queuing system needs to keep track of the current BW being used you can piggy back on that for your needs. Just build two BW based queues (BW greater then your anticipated flows) and then classify the packets into the two queues and the use the TC command to see the current queue utilization. Check out http://www.lartc.org (once is comes back online) or google for the 'Linux advanced Routing & Traffic Control HOWTO' On Mon, Dec 26, 2005 at 08:49:13PM +0800, allen wrote: > Hi All: >=20 > I am trying to create 2 LSP in this example.
