However, (and I agree that this greatly complicates building gateways), I think the gateways SHOULD have some knowledge of what the 'real' bandwidth available into another gateway (and hopefully beyond that gateway to the final destination) is, and try actively not to exceed it. It seems that ICMP source quenches when appropriate would greatly alleviate the problem. (assuming of course that all implementations reacted intelligently to a source quench....) -jcp-
