摘要
针对SDN构建的数据中心,互联网出口带宽无法同时满足所有业务的带宽需求,提出一个基于优先级的带宽保障算法,在满足高优先级业务带宽需求的情况下再满足低优先级业务的带宽需求,保障带宽资源的合理分配。测试结果表明,相比于没有采用带宽保障算法的模拟数据中心,基于优先级的带宽保障算法能确保高优先级业务在总体带宽资源不充足情况下保障业务质量。
In the data center built based on Software Defined Network （SDN） , the Internet export bandwidth cannot meet the bandwidth requirement of all services at the same time, so this paper proposes a priority-based bandwidth guarantee algorithm. Based on the priority of the service, the algorithm gives priority to meet the service bandwidth with high priority and then meet the service bandwidth with low priority in order to ensure the rational allocation of bandwidth resources. The test results indicate that, compared with the analog data center which does not use a bandwidth algorithm, priority-based bandwidth guarantee algorithm can make sure the service with high priority can use more bandwidth resources to guarantee the quality of service under the condition of insufficient bandwidth resources.
