A framework for priority based task execution in the distributed computing environment

Distributed computing environments have been very much in sight for the last one and a half decade. Geographically distributed resources are provisioned to the user tasks in the distributed computing environment as per their requirements. A number of parameters are to be taken into account while provisioning the distributed resources such as task performance and fault tolerance etc. Extensive research efforts are being made towards the improvement of these parameters. In the real time scenario reliability and timeliness are also the important parameters of consideration. Numerous techniques have been proposed and positively acknowledged in the distributed computing environment for achieving the reliability and timeliness of task execution. The Cooperative Computing System (CCS) framework is one such. It has been applied in the grid scenario to achieve the reliability of execution of the highest priority task, but due to its generality, it can also be applied to any distributed computing environment. In this paper an idea is presented to extend the CCS framework for priority based execution of the user tasks in the distributed computing environment.
