Abstract
In this work, we study the problem of deploying and operating correlated data-intensive vNF-SCs in inter-datacenter elastic optical networks. Requiring for a set of correlated data-intensive vNF-SCs, the service completion time (SCT) of a network service is related to the maximum branch completion time of those vNF-SC branches, making the correlation awareness of importance for the problem optimization. Being aware of it, we propose a dynamic programming based optimization scheme for the deployment and operation of single vNF-SC branch and two correlation-aware service provisioning algorithms to minimize the average SCT of network services. Simulation results verified that the proposed algorithms can effectively reduce the average SCT of network services compared with a benchmark algorithm that ignores the importance of correlation awareness.
在这项工作中,我们研究了在数据中心间弹性光网络中部署和运行相关数据密集型vNF-SCs的问题。网络服务的服务完成时间(service completion time, SCT)与这些vNF-SC分支的最大分支完成时间有关,这使得相关意识对问题优化具有重要意义。考虑到这一点,我们提出了一种基于动态规划的vNF-SC单分支部署和运行优化方案,以及两种关联感知的业务发放算法,以最小化网络业务的平均SCT。仿真结果表明,与忽略相关性感知重要性的基准算法相比,所提算法能有效降低网络服务的平均SCT。
