An Innovative Hybrid P2P Location Network for P2P Workflow Systems

P2P workflow systems meet the development trend of workflow systems. The running path optimization (the path with the minimum running time which consists of the services discovery time and the task execution time) in full-distribution(decentralized) environments has been a bottleneck restricting the performance of P2P workflow systems. Aiming at this problem, this paper proposes an innovative hybrid P2P location network by introducing a novel structured P2P network which effectively reduces the service discovery time and the search bandwidth with 100% location precision at each step and a novel decentralized workload balance network which optimizes the tasks execution time at each step with little churns of network to P2P workflow systems for the first time to fit the global optimal running path with the sequence of the optimal single running steps.
