    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 (probability on the order 10−7 or smaller), 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. In addition, the dynamics of queueing delay provides scaling with respect to network capacity. This helps maintain stability as a network scales up in capacity.

    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 in response to packet losses. Transmission rates can be maintained without compromising loss recovery. The invention uses just-in-time Packet Expiration, Transmission Order Queue, 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). 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.

    摘要： This disclosure provides a method of routing communications over a network through an intermediate destination, and it also provides a “universal proxy” that may be used for this purpose. A host wishing to deliver information to a client sends packets as part of a first exchange or “session” to the intermediate destination, which performs error detection and recovery for received packets. The intermediate destination then (if desired) masks the source and transmits the information to the client in a second session, with the intermediate destination controlling transmission (e.g., specifying transmission protocol) and performing loss recovery as appropriate. This methodology enables a number of applications, including masquerading of source identity through the intermediate destination, and TCP acceleration (e.g., by subscribing to a service where the intermediate destination is used to accelerate communications or offer special types of processing or services). A “universal proxy” can be implemented as a single network appliance, accessible to act as a proxy from anywhere on a wide area network (e.g. the Internet, using an IP address). If desired, the universal proxy can also be configured as a two-way proxy.
