    摘要： The present invention is a delay based model and in fact uses queuing delay as a congestion measure, providing advantages over prior art loss based systems. One advantage is that queuing 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 queuing 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 queuing 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 queuing delay provides scaling with respect to network capacity. This helps maintain stability as a network scales up in capacity.

    摘要： Present invention provides an efficient way of enhancing male erectile function, without the fear of unknown long-term ill-effect as a result of taking medication orally. The additive of present invention can be used by condom manufacturers directly as part of the lubricant coating. The composition of the additive pursuant to present invention will cause the dilating and expansion of arteries sending blood to the chambers of corpora cavernosa and corpus spongiosum, and at the same time, cause the restricting and contracting of veins that take blood away. As a result, the hardness of penile erection is increases. Particularly, the staying power is enhanced and time of erection is prolonged, leading to increased sexual intercourse time and better sexual satisfaction.

    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 with out 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.
