This provides several advantages. Tags can have a wide spectrum of forwarding granularities; at one end of the spectrum a tag could be associated with a group of destinations, while at the other a tag could be associated with a single application flow. At the same time forwarding based on tag switching, due to its simplicity, is well suited to high performance implementation. These factors facilitate the development of a routing system which is both functionally rich and scalable. In addition, tag switching simplifies integration of routers and ATM switches by employing common addressing, routing, and management procedures. This talk will provide an overview of the tag switching architecture. It will provide examples of the ways tag switching can be used to support unicast and multicast forwarding, quality of service, traffic engineering, and hierarchical routing. The relationship of tag switching to other technologies (such as IP switching) will also be discussed.
