Abstract:

Many problems may occur during a large scale deployment of VMs, such as overall load imbalance in data center and high VM deployment rejection rate. This paper proposes a resources rating based placement algorithm (RRPA). By considering the affinity relationship between VMs, the topological relationship between PMs, and the connection link bandwidth, one or several PMs mostly appropriate for VNFs deployment are chosen. The simulation results show that RRPA has a higher degree of resource equilibrium and lower rejection rate of deployment than existing methods under the same condition.
