Real-time scheduling with security awareness for packet switched networks

摘要

Conventional real-time scheduling algorithms provide timing constraints to network applications without enhancing or optimizing the security service according to the network dynamics. In this paper, we propose a GAIA multi-agent system that combines the functionality of real-time scheduling with the confidentiality security service enhancement for packet switched networks. The real-time scheduling uses the differentiated earliest deadline first scheduler. The security service enhancement scheme adopts a resource estimation methodology. The proposed system provides the required quality-of-service for the real-time data traffic while adaptively enhancing the packet's confidentiality security service level. The buffering systems at the edge router and the destination nodes are optimally used to protect the network from being congested by heavy traffic load.
