With the rapid growth of networks in scalability and complexity, it is increasingly hard to manage network resources to provide QoS-guaranteed services as demanded. In this paper, we propose a policy-based application-aware network QoS management architecture for grid environment. First, application QoS requirements can be caught by grid supporting middleware; they will then be decomposed by domain, translated into technique policies in policy engine, and enforced through real QoS guarantee mechanisms; finally, QoS monitor will collect network runtime information, monitor, report, and, if necessary, modify the policy translation process through a real-time feedback mechanism, so as to achieve adaptability and application-awareness of network QoS management. The author illustrates a case of the aforementioned architecture as well.
