摘要： In Asynchronous Transfer Mode (ATM) communications networks, certain congestion control features, such as Partial Packet Discard (PPD) and Early Packet Discard (EPD), operate on ATM cells that have been segmented from ATM Adaptation Layer #5 (AAL5) frames (packets). AAL5 frames are automatically detected by observing transitions of an indicator in the ATM cell header unique to AAL5 traffic. Automatic detection of AAL5 traffic allows enablement of packet-aware cell discarding techniques such as PPD and EPD on a Virtual Channel Connection (VCC) basis, whether in a switch for a VCC or for a Virtual Path Connection (VPC) to which the VCC belongs.

摘要： The invention resides in the field of transferring data and other information from multiple asynchronous TDM channels across a synchronous interface in digital blocks of a preset length. Presently, transfer of data and timing information requires serial transmission of frame payload, qualified with clock and frame pulse indications. A separate set of these signals is required in both directions for each port or physical link. An interface of the invention permits data transfer in blocks which are uniquely identified for a specific port or links and the position of the block within the frame (if the transfer is one of framed data). The invention greatly reduces the number of required signals, thus enabling reduction of pin count requirements and an increase in the number of serviced ports.

摘要： An ATM network carries several categories of services, each having its own traffic characteristics and performance requirements. The ABR (available bit rate) service category is the only existing one suited for high-reliability data communications, such as file transfer, LAN emulation, etc. The invention relates to the control of ABR traffic flow in an ATM network, to quickly utilize the bandwidth left unused by higher priority service categories while minimizing ABR cell loss, and maintaining fairness among ABR connections. On each ABR connection, the source end system periodically sends RM (resource management) cells to the corresponding destination end system which loops them back to the source. The ATM network may instruct the ABR sources of the exact rates it can support by modifying a certain field in the RM cells. The invention relates to techniques of deriving the proper explicit cell rate for each ABR connection which can grow to a fair level even under special conditions.
