摘要： The invention provides a method and apparatus for decoupling loss recovery from congestion and window control. The system provides improved performance in high loss environments such as wireless links. The system avoids unnecessary window adjustment response to packet losses. Transmission rates can be maintained with out compromising loss recovery. The invention uses just-in-time Packet Expiration, Transmission Order Queue (302), a Forward Retransmission Algorithm and Window Control to provide improved performance. The invention maintains a queue of packets in flight called the Transmission Order Queue (TOQ) (302). When an acknowledgement is received for a packet in the in-flight queue, that packet is removed from the queue. If a packet is still in the queue for a certain threshold time, the invention assumes that it is lost. At that point, the packet is removed from the in-flight queue and the packet is retransmitted (304).

摘要： The present invention is a delay based model and in fact uses queueing delay as a congestion measure, providing advantages over prior art loss based systems. One advantage is that queueing delay can be more accurately estimated than loss probability. This is because packet losses in networks with large bandwidth-delay product are rare events under TCP Reno and its variants , and because loss samples provide coarser information than queueing delay samples. Indeed, measurements of delay are noisy, just as those of loss probability. Thus, another advantage of the present invention is that each measurement of queueing delay provides multi-bit information while each measurement of packet loss (whether a packet is lost) provides only one bit of information for the filtering of noise. This makes it easier for an equation-based implementation to stabilize a network into a steady state with a target fairness and high utilization.
摘要翻译：本发明是基于延迟的模型，实际上使用排队延迟作为拥塞度量，提供了优于现有技术的基于损失的系统的优点。一个优点是可以比丢失概率更准确地估计排队延迟。这是因为具有大带宽延迟产品的网络中的数据包丢失是TCP Reno及其变体下的罕见事件，并且因为丢失样本提供比排队延迟样本更粗糙的信息。事实上，延迟的测量是嘈杂的，就像丢失概率一样。因此，本发明的另一个优点是每次排队延迟的测量提供多位信息，而每次测量分组丢失（分组丢失）只提供一个信号用于滤波噪声。这使得基于方程式的实现更容易将网络稳定到具有目标公平性和高利用率的稳定状态。

摘要： The invention provides a congestion control scheme that is a delay based scheme that includes a scalable queue size and one-way queueing delay measurement to reduce network congestion. Queue size is managed by queue control, a scalable utility function, dynamic alpha tuning, and/or randomized alpha tuning. One-way queueing delay is accomplished by measuring backward queueing delay management using various methods of estimating the receiver clock period. Embodiments include estimating the receiver clock period using single sample and multiple sample periods. The system includes a method for detecting route change.
