Abstract
A multitude of applications require simultaneous access to multiple kinds of resources scatted in distributed sites. This problem is known as resource co-allocation which has evolved as a hot topic in network computing. How to design a kind of high-performance protocol for deadlock and livelock avoidance resource co-allocation becomes a challenging problem. In this paper, we propose a new protocol OODP3 (Optimal ODP3) which is based on the currently popular protocol ODP3 (Order-based Deadlock Prevention Protocol with Parallel requests).OODP3 not only inherits the advantage of ODP3 but also guarantees the fulfillment of resource co-allocation within polynomial time. Theoretical proof is conducted to verify the correctness of OODP3. Experimental results also show that OODP3 achieves the better performance improvements than the existing deadlock and livelock avoidance protocol.
