We present YAAP: a generic active network architecture with the ability to manually and dynamically deploy network services within distributed network nodes and providing a secure execution environment (EE). It also demultiplexes active network packets to multiple EEs located on the same network node. Currently, YAAP prototype is implemented under the Linux operating system, with some parts built in kernel-space and others in user-space to optimize performance. This paper describes the node architecture, serves as an internal description of the implementation, and also demonstrates the utility of YAAP’s activeness by experimentally deploying active applications using the current implementation.
