| Active networks have recently received significant attentions due to their abilities to introduce programmability into a network Although numerous amounts of works have been done to study their benefits, they seldom concern interoperability in active networks that consists of routers with multiple execution environments. Specifically, network services that are developed using one particular environment are unable to run on routers that support other environments. To address this problem, this thesis presents a unified active networks programming framework called Active Network Socket Programming (ANSP). This framework introduces a unified programming model to allow service developers to write their services that are able to run on top of different environments. The framework also introduces translation mechanisms for existing network architectures to help these services work seamlessly under heterogeneous networks. A prototype based upon ANSP has been built, and evaluation results based on several case studies are presented. |
