- Abstract
- Network function virtualization based service chaining has recently received significant attention. In cloud environment, virtual machine typically be scheduled to load balancing among computing nodes. Therefore, the relation between virtual machines is not considered when it is scheduled. However, the location of virtual machines be able to affects network performance for intra virtual machines. Video/image processing and transmission are key processes for cloud-based over-the-top content provider. In this paper, we propose a pseudo service chaining mechanism for efficiently allocating computing nodes in a service chain to guarantee quality of services. The mechanism defines a pseudo service chain to reduce the network overhead which mainly causes performance degradation and places highly correlated virtual machines on the nearest computing node. The performance of proposed mechanism was evaluated on real cloud testbed.
