摘要
往返时间(RTT)、目标速度(CIR)以及重传超时(RTO)等因素导致了带宽分配的不均匀。通过研究带宽与这些因素的关系,在时间滑动窗口三色标记器(TSW3CM)的基础上,提出一种CIR、RTT、RTO感知的标记器(CRR3CM)。该标记器完成了在各汇聚流之间对剩余带宽的公平分配,减少了目标速度、往返时间,以及重传超时因素对带宽分配的影响。模拟实验表明,与TSW3CM相比,该算法有效地提高了TCP流之间带宽分配的公平性。
Commited information rate（CIR）, round trip time （RTT） and retransmission timeout （RTO）, can bias bandwidth assurance. Through researching the relation between bandwidth and these factors, this paper proposed a CIR, RTT, RTO aware marker（CRR3CM） based on time sliding window three color marker（TSW3CM） ,which could achieve proportional fair sharing of excess bandwidth among aggregates and mitigate the impact of CIR, RTT, RTO for bandwidth assurance. Simulation results indicate that the algorithm can improve the performance of fairness bandwidth allocation between different TCP flows.
