Well, to me, central to the notion of the Internet architecture and more specifically to a routing architecture is the notion of topology. It would seem somewhat challenging to be able to describe topology without being able to describe a graph. And if we want to be able to describe a graph, we need to be able to articulate the nodes and edges in that graph. I don't see how to do this with just service identifiers. Regards, Tony Right.For the same reason I don't understand either to have a service identifier discussion here. Routing is about recognizing and utilizing topology.By knowing the topology you can see all paths in forward direction wrt a given destination as well as which network part would use you for transit (the rear mirror). You have much less by assembling hundred thousands of routes instead. Heiner
