Real-time scheduling with security awareness for packet switched networks

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.
