Abstract

This paper describes our effort to build an extensible router in support of active networks.Our work is driven by two goals:(1) supporting the injection of new functionality into a router, and(2) exploiting commercially available hardware.Our approach is a hierarchical architecture, in which packet flows traverse a range of processing/forwarding paths.This paper both presents the architecture, and describes our experiences implementing the architecture across a combination of general-purpose and network processors.
