虚拟光网络中NFV资源分布式调度设计

Design of NFV resource distributed scheduling in virtual optical network

为进一步提升虚拟光网络应对海量大数据计算请求的能力,构思一种基于约束的响应度解决方案。该方案依托网络功能虚拟化的优势,本着分而治之的原则为光网络各类资源规划分布式调度模型,充分考虑网元相关性对服务质量的影响。同时以响应度为中心引入甄选机制和最优桥接算法降低映射频度改善映射精度。结果表明,分布式调度方案能够科学地应对虚拟光网络发起的请求,具有良好的前瞻性。

In order to further improve the ability of virtual optical network(VON)to deal with massive big data computing requests,a constraint based responsiveness solution is proposed.Based on the advantages of network functional Virtualization(NFV),this scheme plans a distributed scheduling model for all kinds of optical network resources according to the principle of divide and conquer,and fully considers the influence of network element correlation on quality of service(QoS).At the same time,the selection mechanism and optimal bridging algorithm are introduced to reduce the mapping frequency and improve the mapping accuracy.The investigation results show that the distributed scheduling scheme can scientifically respond to the requests initiated by von and has good foresight.
