| 摘 要： | 针对非一致内存访问架构的集群系统，探讨了虚拟网络功能链的时延问题，以及重用已部署的虚拟网络功能提升资源利用率机制。形式化定义了面向最小化时延的虚拟网络功能部署问题，证明其为NP难问题，提出了基于马尔可夫链概率迭代的部署算法MarVNFP。实验证明，与典型的虚拟网络功能部署算法MRP相比，MarVNFP算法能减少虚拟网络功能链近40%的跨域数据传输，有效降低了时延。

| Abstract: | This paper investigates low latency Virtual Network Function（VNF） chain deployment, based on Non-Uniform Memory Access（NUMA） architecture. To improve the resource utilization, certain number of VNFs are reused. This paper formulates the VNF deployment problem, which is proved to be NP-hard, and proposes an iteration deployment algorithm MarVNFP based on Markov chain. Extensive simulations show that MarVNFP reduces nearly 40% data transmission delay compared with well-known MRP algorithm. |
