With IP, to get decent QoS, you need a bit of excess bandwidth on the connection. With contention for the pipe at any point in the path from sender to receiver, the connection reverts to a 'best efforts' un-policed connection. Hmm, maybe I'm wandering into the Pub wearing a weird hat. After all, this is the Lartc mail list. >What cannot be done is make two links work like one with the >sum of the bandwidth. I can see your point. I didn't say that it was going to be easy. == I just 'measured' my DSL bandwidth at 632 kbits/sec and my Cable bandwidth at 897 kbits/sec (using bandwidthplace.com) == BobG
