摘要： 针对虚拟计算资源繁多、分布广泛和动态变化的特点，提出一种基于拓扑相关组的资源协同发现模型。采用前缀匹配的路由机制，使同一应用所需的各资源之间的逻辑连接与网络底层拓扑相一致，确保查询到的资源尽可能与用户节点相邻，从而实现关联资源的发现。实验结果表明，该模型能提高资源协同发现的效率。

Abstract: Aiming at the characteristic that virtual computing resources are distributed various, widely various and dynamic change, this paper proposes a resource cooperative discovery model based on topological-related groups. It uses prefix matching routing mechanism. The resources used in the tasks decomposed from a same application are related in terms of the underlying topology of the network. It ensures resource as far as adjacent to user node, and realizes cooperative resource discovery. Experimental result shows that the model can improve the efficiency of resource cooperative discovery.
