Abstract

The Internet Emergency Preparedness (IEPREP) working group of the Internet Engineering Task Force (IETF) is investigating to provide solutions for emergency systems based on IP networks. With the emergence of new applications in heterogeneous network environment, the need of adaptation to serve in emergencies with acceptable Quality of Service (QoS) is urgently required. With the help of IETF's integrated and differentiated services extending over best effort Internet, it is possible to reach certain Service Level Agreement (SLA) but not sufficient to serve all applications. In this paper we proposed a dynamic differentiated service approach for emergency traffic so that during emergency situation the routers in the source-destination shortest path tune themselves using Software based Router Agent (SRA) to serve the emergency traffic with optimum effort. With QoS assurance infrastructure, applications specify what they want and network tries to honor their request. Here we presented how SRA and XML based Quality of Service specification (XQSPec) played important role to tune IP routers in access and transit network to get better QoS for time sensitive emergency traffic over the best effort Internet.
