A Novel Active Network Architecture Based on Extensible Services Router

摘要

Active networks are new kind of packet-switched networks in which packets have code fragments that are executed on the intermediary nodes (routers). The code can extend or modify foundation architecture of network. In this paper, the authors present a novel active network architecture combined with advantages of two major active networks technology based on extensible services router. The architecture consists of extensible service router, active extensible components server and key distribution center (KDC). Users can write extensible service components with programming interface. In order to protect the information in the network, we design a simple authentication protocol. At the present time, we have finished the extensible services router prototype system based on Highly Efficient Router Operating System (HEROS), active extensible components server and KDC prototype system based on Linux. We have built a video on demand system based on our active network technology.
