摘要Knowledge of the queue length of the bottleneck link has many potential applications such as congestion control, traffic engineering, traffic policing, content adaptation, QoS monitoring and provisioning, etc. A recent work proposed a new Sum-of-Delay with Timestamp (SoD-TS) algorithm which can accurately estimate queue length in mobile networks with both bandwidth variations and uplink delay variations by exploiting the existing TCP Timestamp option. By making use of SoD-TS we developed a novel transport protocol - queue-length-aware TCP (TCP-QLA), that tackles the problem of bufferbloat to provide better QoS for applications requiring low end-to-end delay and/or high bandwidth utilization. Trace-driven simulation shows that compared to TCP CUBIC TCP QLA can reduce the RTT by a factor of 2.7 while still achieving over 97% bandwidth utilization. Moreover, TCP-QLA further reduces RTT by 50% compared to delay-based TCP such as FAST TCP and TCP Vegas.
