摘要

网络虚拟化可以实现不同的虚拟网络部署在相同的物理网络之上,在不改变现有网络体系结构的基础上,建立互联网的新型体系架构,解决现有网络的"僵化"问题.将无线接入网融合到虚拟化资源管理架构,并基于拓扑识别和最小割集原理,提出了面向容错的虚拟资源映射算法,提高资源分配的可靠性.仿真验证表明,在节点压力较大、容错故障率较高的情况下,改进后的算法具有更高的虚拟请求成功率和更低的资源占用率.
        Network virtualization could achieve multiple heterogeneous virtual networks(VN) deployment in a shared infrastructure provider(In P) network. To solve the existing network "rigid"problem,VN used the existing internet's architecture without changing it. Based topology discriminating and minimum cutest,the virtual network mapping algorithm was introduced to improve the reliability of resource allocation. The simulation showed the improved algorithm had higher rate of virtual request and lower occupancy rate in the condition of high node pressure and high failure rate of fault-tolerant.
