摘要:

摘 要:以结构化拓扑为基础,采用CAN(content addressable network)协议,提出了一种新的云计算网络路由算法。该算法以M-CRP技术为基础,改进传统CAN协议,组网时在物理上相近的节点会处于逻辑上相邻的位置;相应的路由机制也对物理拓扑结构给予充分的考虑,优先考虑物理临近并且通信成本较低的节点;自适应机制网络状态不断变化,M-CRP-CAN(multiple-CDN-based relative network positioning)在组网、路由、自适应等机制都有较强底层物理拓扑结构感知性。实验表明,算法能够提高数据的交换效率,减少了网络中不必要的跨域流量,减少骨干链路的负载,提高了云计算网络性能。

Abstract:

Based on the traditional CRP mechanism,a new mechanism called M-CRP which is more adapt to the cloud computer mechanism was advanced.Based on traditional CAN,a new mechanism called M-CRP-CAN which make full use of M-CRP and make not only the CAN framework structure award of the physical location of nodes was advanced but also the routing mechanism give more thought about the physical topology.The self-adaption can make the M-CRP-CAN has more ability to change according to the net status.In network simulation platform,the experimental results show that M-CRP’s performance is better than CRP in aspect of efficiency and precision.This M-CRP improves CRP from aspect of efficiency,precision and performance with multi-level mechanism,which make the node in cloud,has more perception to the underlying topology.In the meantime the M-CRP-CAN with M-CRP approach has realized localization download and greatly raised the data transfer rate,reduced the cross-traffic in backbone network and improve the network performance therefore enhance cloud computing system efficiency.,

Key words: cloud computing, route, content addressable network
