Content-Based Addressing and Routing: A General Model and its Application
Antonio Carzaniga, David S. Rosenblum, Alexander L. Wolf · 2000
The designers of communication networks are being challenged by the emergence of a new class of addressing and routing scheme referred to as content-based addressing and routing. This new approach differs from traditional unicast and multicast schemes in that it performs routing based on the data being transported in a message rather than on any specialized addressing and routing information attached to, or otherwise associated with, the message. An example of an application for content-based addressing and routing is an event notification service, which is a general-purpose facility for asynchronously and implicitly conveying information from generators of events to any and all parties expressing interest in those events. In order to implement content-based addressing and routing, we can adopt well-known and successful network architectures and protocols, provided that we understand how to map the core concepts and functionalities of content-based addressing and routing onto ...
