摘要： A method and equipment for accelerating throughput of communication segments from a sender (30) to a receiver (40) each of which include a protocol layer (30a 40a) for providing such segments, the method in case of TCP including a first step (20a) in which the sender protocol layer (30a) initializes a congestion window (cwnd) to some initial size (iwnd) and increases the congestion window by one segment each time it receives an ACK, but upon receiving an indication of low congestion, performs a step (20c) of accelerated start in which it sets a slow start threshold (SSTHRES) to a standard initial value (typically 65535) and re-initializes cwnd to a new value, and the sender protocol layer (30a) then increments cwnd at one or another predetermined rate--depending on whether the start immediately follows a new connection or instead follows a transfer of an existing connection to a new path--in respect to received ACKs.

摘要： The link layer (68, 64) of the sending end of a wireless link (66) is enhanced (10, 74) by providing a mechanism for discriminating (36, 38; 79, 82) between special, critical or otherwise important packets from among a plurality of packets sent over the wireless link. Special link layer treatment (42; 89) is accorded to such special, critical or otherwise important packets, while the remaining packets are subjected to normal link layer treatment (44; 86) before transmission over the wireless link.

摘要： The present invention provides an enhanced H-ARQ scheme that optimizes bandwidth utilization and spectrum efficiency. When an H-ARQ attempt is unsuccessful due to loss or error over a hop between the BS and MS/SS, then only the first node in the hop chain that fails to decode the packet transmits another H-ARQ attempt. The BS determines the first node that fails on decoding based on certain information such as the feedback information sent from the nodes on the path. The previous node of the failed node is then instructed to retransmit by the BS.
