<p>A new overlay apparatus and method to augment best-effort congestion control and Quality of Service in the Internet called edge-to-edge traffic control (Fig.3) is disclosed. The basic architecture works at the network layer and involves pushing congestion back from the interior of a network, distributing across edge nodes (202, 206, Fig.3) where the smaller congestion problems can be handled with flexible, sophisticated and cheaper methods. The edge-to-edge traffic trucking building blocks thus created can be used as basis of the several applications. These applicaitons include controlling TCP and non-TCP flows, improving buffer management scalability, developing simple differentiated services, and isolating bandwidth-based denial-of-service attacks. The methods are flexible, combinable with other protocols (like MPLS and diff-serv), require no standardization and can be quickly deployed.</p> |
