SDN-based Data Center Network Management for Cloud 3D Rendering Video Service
- 원문 URL
In this paper, we present a SDN-based cloud data center system for cloud users in order to satisfy the QoS. In general, a tree-based topology is used for cloud data centers but this architecture can't guarantee QoS because of the bottleneck problem. Also the conventional solutions based on SDN are not suitable for cloud data center network. It is essential to consider network status with server processing time for the QoS-guaranteeing service. To address these problems, we propose a CSPF-based path selection algorithm. It finds optimal path to efficiently use links that is not overloaded and to satisfy the user demand for 3D rendering game. Finally, simulation results are provided to show the performance of the proposed algorithm.
