ABSTRACT
We present NetServ, an extensible architecture for core network services for the next generation Internet. The functions and resources available on a network node are broken up into small and reusable building blocks. A new core network service is implemented by combining the building blocks, and hosted in a sandbox-like execution environment that provides security, portability, resource control, and the ability to deploy modules dynamically.
We describe our first prototype, a novel combination of the Click router and the Java-based OSGi module system. Our measurement results indicate that the processing overhead incurred by the Java layer is a reasonable trade-off for the level of modularity we achieve in our system.
