Abstract: A technique of allocating data cells by a segmentation and reassembly (SAR) controller for transmission on a network connection such as an asynchronous transfer mode (ATM) network connection provides a scaleable sustainable cell rate (SCR) when the sum of the SCRs of virtual circuit exceeds the connection bandwidth. In addition, bandwidth can be shifted from a VC which is using less than its allocated SCR to a VC that is exceeding its SCR. In addition, the method enables a VC to exceed it peak cell rate (PCR) to some extent. The method and system of the disclosed embodiment can also be employed to dynamically adjust SCRs and PCRs in a variable bandwidth channel and is programmable and thus more flexible and less expensive than possible hardware solutions.

Abstract: A first module (10) sends a message comprising a plurality of data characters to a second module (20) provided, however, that upon sending an individual data character, the first module waits to receive an acknowledgement character from the second module before proceeding to send another data character.

Abstract: A method of performing an autobaud function in data communication equipment utilizing a predetermined state flow machine for processing the bits of at least a portion of a command bit stream for identifying transmit characteristics of a corresponding information bit stream.
