Future Architecture and Mechanisms of the Self-Managing Internet

摘要

This article introduces the architecture and mechanisms of the self-managing future Internet currently being developed by the European Union Seventh Framework Programme (FP7) project EFIPSANS. In this architecture,network functions are divided into four planes:decision,dissemination,discovery,and data. Decision Elements (DEs),managed entities,and other information collecting entities at different planes comprise control loops of four layers:the protocol layer,the function layer,the node layer,and the network layer. DEs and their related control loops contribute to network self-management and self-maintenance. This greatly reduces the need for intervention in the network,thus reducing costs and improving user experience. The European Telecommunications Standards Institute (ETSI) has now established a new Industry Specification Group to standardize the self-managing Internet.
