Active Networks


Active Networks research area has been introduced in early 1990's by several reseach groups. The OPENSIG series of workshops studied programmable networks for telecommunications and introduced open programmable network interfaces, service creation with QoS and separated network control from information transport. In DARPA projects the active network approach focused on IP routers where control and data paths were combined. The capsule model for carrying code was introduced as an extreme approach.

The Active Networks project seeks an approach to active networks that supports high performance while also permitting dynamic modification of network behavior to support specific applications and/or provide new services. The goal is to design and implement Building Blocks at Virtual Network Device Level of IEEE P1520 Reference Model allowing for "fast-path" optimizations while also enabling new services to be defined in software. The project comprises an overall architecture for the active network; application programming interfaces; and experimental studies of the effectiveness of active networks in support of specific applications and services.
