摘要

虚拟集群是指通过共享云数据中心内的资源,为租户提供分布式并行系统的基础。为虚拟集群分配物理资源被称为虚拟集群嵌入问题,它是影响虚拟集群性能和系统资源利用率的关键问题。为了有效缩短虚拟集群嵌入的运行时间,提高收益/成本比,本文提出了一种拓扑感知多路径虚拟集群嵌入算法(TMVCE)。虚拟簇拓扑信息主要包括拓扑网络的程度和紧密度两个因素,有效地用于VCE的测量参数。通过大量的实验测试和相关算法的比较,可以明显看出TMVCE获得了更高的嵌入效率,并在一定程度上提高了收益/成本比。

TMVCE—topology-aware multipath Virtual Cluster embedding algorithm
Virtual Cluster refers to the basics of providing distributed parallel system for tenants by sharing resources in cloud data center. Allocating physical resource for virtual cluster is known as virtual cluster embedding problem, which is a critical issue that affects the performance of virtual cluster and resource utilization of the system. In order to effectively reduce the runtime of virtual cluster embedding and improve the revenue/cost ratio, this paper proposes a topology-aware multipath virtual cluster embedding algorithm (TMVCE). Virtual cluster topology information, mainly including the degree and closeness two factors of topology network, is used efficiently for the measurement parameters of VCE. According to extensive experimental tests and the comparison of correlative algorithms, it is obvious that TMVCE obtains a higher embedding efficiency and, to some extent, improves the revenue/cost ratio.
