摘要： A method and apparatus controls network bandwidth between a first node and a second node on a network. A data element transmitted from the first node to the second node is intercepted. The data element comprises a data portion and a header portion including an original window size. The original window size in the header portion of the data element is replaced with a replacement window size, the data portion of the data element remaining unmodified. The data element is then routed to the second node, the header portion of the data element being coupled to the replacement window size.

摘要： A network access scheme enhances channel utilization under the ALOHA protocol by making use of the FM capture effect. The resulting network access scheme allows a transmitter to transmit a message simultaneously with other transmitters to a receiver without the need for retransmission when the message reaches the receiver with sufficient strength over the strengths of the other transmissions. In one embodiment, the network access scheme is applied to a wireless data network, which includes support to a two-way paging application. Another network access scheme combines the high channel utilization of the carrier sensing multi-access (CSMA) protocol with the FM capture effect to provide even higher expected channel utilization. The resulting network access scheme uses a channel access protocol ("CSMA/AT") which provides an adaptive threshold. An RF transmitter determines, using the adaptive threshold, whether or not to transmit its message. Under CSMA/AT, if the sensed power of other transmissions (RSSI) in the channel is below the adaptive threshold, the transmitter transmits; otherwise, the transmitter backs off.
