Abstract:

The current Internet implements hop-by-hop packet forwarding based entirely on globally-unique identifiers specified in packet headers, and routing tables that identify destinations with globally unique identifiers and specify the next hops to such destinations. This model is very robust however, it supports only a single forwarding class per destination. As a result, the Internet must rely on mechanisms working on top of IP to support quality-of-service QoS or traffic engineering TE. We present the first policy-based connectionless routing architecture and algorithms to support QoS and TE as part of the basic network-level service of the Internet. We show that policy-aware connectionless routing can be accomplished with roughly the same computational efficiency of the traditional single-path shortest-path routing approach.
