Scalable Integrated Services Architecture for Computer Networks

Acts as middle ground between the stateful Intserv and a published stateless architecture (SCORE)Easily scalable while providing delays similar to the Intserv architecture

Network routing: maintains reservation state thereby maintaining incoming and outgoing trafficMaintains the reservation state in a network router to maintain rates of incoming and outgoing traffic

Scientists at the University of California, Santa Cruz have developed a new scalable services architecture for computer networks that replaces the per-flow reservation state in the routers  with a small, bounded aggregate state. The size of this aggregate state and the complexity of the refresh mechanism are determined by network parameters, such as size and class, rather than the number of end-user flows. The invention incorporates a "shaper-battery" (a set of token-buckets arranged in the form of a tree) for aggregating flows into classes defined using the newly developed notion of "burst-drain-time" or "burst ratio". The consistency of aggregate reservations is maintained using AGRE, the first reservation protocol to use diffusing computations for this purpose.
