摘要
当前数据中心网络的传输优化方法由于将缓存管理和主动队列管理两者割裂,无法有效提高数据中心网络性能。为了提高调度效率和应对突发数据流,提出了缓冲区优化策略(记为DCBOpti)。DCBOpti策略有机结合总缓冲区占用率和队列排空时间,准确地推导每个队列的阈值,通过主动管理缓冲区,降低了队列消耗时间和排队时延。实验评估表明,与现有策略相比,DCBOpti策略在不牺牲吞吐量性能的情况下有效改善数据流完成时间的减缓度,有效提升了数据中心网络的传输效率。
The current transport optimization method for data center networks cannot effectively improve the performance of data center network due to the separation of cache management and active queue management.In order to improve scheduling efficiency and deal with burst data flow,this paper proposes a buffer optimization strategy(denoted as DCBOpti).DCBOpti strategy organically combines the total buffer occupancy rate and queue emptying time,and accurately deduces the threshold of each queue.The DCBOpti strategy reduces queue consumption time and queuing delay by actively managing buffers.The DCBOpti policy takes into account the total buffer occupancy and queue emptying time.This paper uses experiments to evaluate the performance of the DCBOpti strategy.Compared with existing strategies,the DCBOpti strategy can effectively improve the slowdown of data flow completion time without sacrificing throughput performance,improving the transmission efficiency of the data center network through buffer optimization.
