Collective Delegation using QoS Metrics

V. Manchala (USA)


Collective Delegation, QoS.


Current research in Internet Computing does not address the problem of specifying and realizing QoS parameters described in a trusted capability. In a Web environment, an Internet server can receive several requests with varying QoS requirements. The server's admission control should either deny or allow the request without degrading the system performance in accordance with service guarantees and other security attributes specified in a digitally signed XML structure called a trusted QoS capability. The problem becomes challenging when requests are accompanied by delegated credentials. The goal is to provide sustenance of Quality of Service while continuing to maintain stability and determinism on servers. This paper develops a mathematical model for QoS based delegation, and describes the process of using such capabilities.
