An active network bandwidth reservation scheme

This paper describes a novel scheme for ensuring quality of service in a dynamically extensible active network. Applications can reserve bandwidth on each link, and the node provides the guaranteed amount by manipulating weights in a fair-sharing scheme. The reservations are represented as objects in the soft state at each node of the network. We demonstrate the versatility of this scheme by showing how to design an active protocol that seeks to reserve end-to-end bandwidth even when no single path can provide enough for its needs.
