一种可视化云对等网络模拟器的设计

Design of a visual cloud-to-peer network simulator

从云计算Iaa S(Infrastructure as a Service)的角度来说,云资源就是提供云计算基础设施服务的物理节点。若使用一致性哈希算法为每个云资源生成一个唯一的资源标识符,该标识符空间便可以把云网络的拓扑结构、云资源索引信息的存储和云资源的定位三者有机地结合起来,从而形成一个结构化P2P覆盖网络。利用此特殊的覆盖网络,可以设计出云资源索引信息的共享方案来解决云资源的快速检索和高效定位问题。为了方便基于对等网络云资源信息共享平台和云资源高效定位算法的深入研究,设计了一个可视化云对等网络模拟器,实验表明该模拟器能够很好地模拟出实际的云环境。

From cloud computing Iaa S（ Infrastructure as a Service） perspective,cloud resource is to provide cloud computing infrastructure services,physical node. Each cloud resources generate a unique resource identifier if used consistent hashing algorithm,the identifier space is able to locate the three cloud storage and cloud resources in the network topology,cloud resource index information is organically combined,thereby forming a structured P2 P overlay network. This particular use of the overlay network,sharing scheme can be devised to cloud resource index resolved quickly retrieve information cloud resources and efficient positioning. In order to facilitate efficient localization algorithm based on thorough research and other network information sharing platform cloud resources and cloud resources,this paper designs a visual cloud peer network simulator. The experiments show that the simulator can simulate the actual cloud environment.
