网络虚拟化环境下资源重分配机制

In order to improve the network of virtual environments (NVE) network resources and allows virtual network service providers (SP) maximum of total receipts, this builds the model of resource allocation system, SP can trade their resources and resource-rich resources SP can be transferred to the SP of a resource shortage. Analysis on the basis of this model and offered two types of network resource allocation scheme: semi-distributed allocation and distributed allocation scheme. Semi-distributed allocation and programme mechanisms using price control center and distributed two double auction free trade system, each SP to maximize their revenues of principles based on the current market price for resource transactions. Simulation results show that the proposed semi-distributed transaction mechanism and distributed transaction mechanism convergence and eventually reach the optimal results.
