An enhanced virtual cluster embedding strategy with virtualized SDN

摘要: Allocating physical resources for virtual cluster is known as embedding problem, which has a very important influence on the performance of and resource utilization system. Meanwhile embedding, relative to network, includes more elements: machine, switch, link, SDN controller system controller. These components need be considered comprehensively adjust influencing factor weight proportion enhance embedding. This paper proposes an enhanced strategy, called EVCE, combines network with form coordinates optimization centrality, correlation property fragmentation achieve VCE. According extensive experiments comparison correlative algorithms, it obvious that EVCE effectively reduces delay, obtains higher efficiency and, some extent, improves revenue/cost ratio delay.
