摘要:
限制视频业务发展的主要矛盾是其高带宽、低时延的网络要求与核心网网络环境复杂多变和Best-Effort服务模型之间的矛盾. 为了解决这一问题,在基于SDN的核心网络框架下,提出了一种基于时间槽的可降带宽的视频业务分级动态资源预约算法. 该算法在可降带宽的动态资源预约算法的基础上引入分级策略,如发现不满足视频业务带宽需要的时候采用降带宽的方式进行处理,同时,将高优先级的会议请求在带宽分配队列中前置. 通过仿真对算法进行测试,结果表明,该算法能进一步增加高优先级视频业务资源预约的成功率.
Abstract:
The main contradiction that limits the development of video services is its high-bandwidth, low-latency network requirements and the complex and variable core network environment and Best-Effort service model. In order to solve this problem, this paper proposes a tiered dynamic resource reservation algorithm for video services based on time slot and bandwidth reduction under SDN core network framework. The algorithm introduces a grading policy on the basis of the bandwidth-reducing dynamic resource reservation algorithm, and adopts bandwidth reduction when the bandwidth requirement of the video service cannot be satisfied. At the same time, the bandwidth is reserved for high-priority conference requests. The simulation results show that the algorithm can further improve the success rate of high-priority video service resource reservation.
