摘要
传统网络架构中网络设备同时集成控制逻辑与转发逻辑,在转发处理对时延和抖动要求较高的流媒体数据时,网络资源利用率较低。本文通过对SDN流量调度机制和Open Flow型、Over Lay型和控制平面型三种流量调度方案研究,基于控制平面型SDN流量调度方案能够在现有网络设备基础上较好的解决流媒体流量调度问题,提高网络内流媒体流量调度效率。
In traditional network architecture,network devices integrate control logic and forwarding logic.When the network equipment forwards the streaming media data with high delay and jitter requirements,the utilization rate of network resources is low.In this paper,SDN traffic scheduling mechanism and open flow,over layer and control plane traffic scheduling schemes are studied.Based on the control plane SDN traffic scheduling scheme can better solve the problem of streaming media traffic scheduling on the basis of existing network equipment,and improve the efficiency of streaming media traffic scheduling in the network.
