基于SDN的动态资源分配算法

Dynamic Resource Allocation Algorithm Based on SDN

针对软件定义网络(SDN)能够执行多种并发、动态网络测量任务的特点,提出一种自适应的网络测量框架.该框架能动态调整分配给各测量任务的资源,从而确保用户层面上对测量精度的要求.设计并实现了相应的系统原型,并采用3种不同的网络测量业务对该方法进行验证.实验结果表明,该方法在任务测量精度满足率和任务拒绝率上具有更优的性能,与传统方法相比精确性更高.

A new measurement method based on adaptive network framework was presented,which can dynamically adjust the resources allocated to each measurement task,so as to ensure that the user level requirements for measuring accuracy.A prototype system was designed,implemented and verified with three different kinds of network measurement business.The experiment data show that the proposed method has advantages in task accuracy satisfaction ratio and task rejection ratio.And it is proved the proposed method has higher accuracy compared with the traditional method.
