No! I am not reinventing MPLS... I am reinventing IntServ... It's different! In MPLS each flow is routed based on its label and the label is only locally unique, meaning that in each node it is changed for a different label and then sent through some interface (just like VP and VC in ATM). But in my case (just like in IntServ), the flow label, source IP and destination IP triple is what identifies each flow, i.e. the flow label is unique with respect to each src/dest pair. For this reason each packet must be routed based on this triple (in fact, based on a pair is sufficient), and the flow label is not changed along the path to the destination... That is a really different approach. And not a new a approach, I may say. I am not inventing anything, just applying existent solutions to specific scenarios...
Well, if somebody knows anything about implementations of IntServ in Linux, my question remains opened... Anyway, thanks for your help.
Cheers,
Rafael
