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.
