Service Time Distribution of Tasks using Adapt-policy

Authors(2) :-Ramyadevi.K, Anitha. B

Task assignment in server farms We propose an adaptive task assignment policy named as ADAPT-POLICY, which is based on the conception of many static-based task assignment policies ADAPT-POLICY defines a setof policies for a given system taking into account the specific properties of the system. They have different execution characteristics under different workload conditions The objective is to use the task assignment policy with the best performance . Which task assignment policy performs the best depends on the traffic conditions that vary over time. ADAPT-POLICY determines the best task assignment using the service time distribution of tasks (and various other traffic properties), which is estimated and then it adaptively changes the task assignment policy to suit the most recent traffic conditions. The experimental results show that ADAPTPOLICY can result in significant performance improvements over both static and dynamic task assignment policies.
