摘要： A transmission system can perform flow control even if a flow control instruction is invalidated, and even when the transmission system malfunctions, it can autonomously recover to normal operation for communications. A flow control instruction sender has at least one of two functions including a normal transmission mode to send a flow control instruction for flow control over a congestion state if an event, such as the occurrence of a congestion or the removal of a congestion, occurs when a data receiver receives data, and an autonomous transmission mode to select one of a plurality of congestion states at present in each period and autonomously send a flow control instruction corresponding to the selected congestion state. The flow control instruction sender preferentially sends a flow control instruction in the normal transmission mode in which a congestion actually occurs or is actually removed, when timings of the normal transmission mode and the autonomous transmission mode coincide with each other. A flow control instruction receiver receives a flow control instruction to perform flow control by stopping sending data and sending data.

摘要： An ATM network includes a plurality of ATM-LANs which are connected through an ATM-WAN, when a source terminal and a destination terminal belong tb separate ATM-LANs connected through the ATM-WAN, the congestion control is performed as follows. When congestion occurs in an ATM-LAN in which the source terminal exists, the congestion control is performed by the BECN mechanism and when congestion occurs in an ATM-LAN other than the ATM-LAN in which the source terminal exists, the congestion control is performed by the FRP mechanism. When the source terminal and the destination terminal exist in the same ATM-LAN, the congestion control is performed by the FECN mechanism. Thus, in the ATM-LAN, cell loss can be suppressed upon occurrence of congestion.

摘要： An amount of data to be distributed to each receiving terminal is dynamically controlled for each receiving terminal in response to a congestion of each of plural receiving terminals. When a determination of an RR (Reception Report) returned from the receiving terminal results in a very low rate of packet loss, an adaptive control mixer distributes communication data transmitted from a transmitting terminal to the receiving terminal without reducing the communication data. On the other hand, the determination of the RRs returned from the receiving terminals results in a high rate of packet loss, for example, 50% and 90%, respectively. In this case, the adaptive control mixer reduces, for example, 50% of the communication data transmitted from the transmitting terminal and then distributes the data to the one receiving terminal. The adaptive control mixer reduces, for example, 90% of the communication data and then distributes the data to the other receiving terminal.

摘要： A congestion control system appropriately controls congestion of cells independently of the configuration of source and destination terminal units in, for example, an ATM switching unit, and shortens the time taken from the generation of congestion to the start of control. A buffer for switching the cells in a switch device adds to the cells transmitted through the switch device an EFCI for use in notifying the destination terminal unit of the congestion state of the cells. An output line device detects together with a VPI/VCI the EFCI added to the cell to be output from the switch device to the destination terminal unit. The output line device transmits to the switch device the VPI/VCI corresponding to the detected EFCI and an RM cell in which backward congestion indication is set.

摘要： A cell transmission rate control scheme in ATM network, capable of preventing incorrect updating of information in a resource management (RM) cell. The RM cell having an explicit cell rate field is transmitted and returned between the first and second end-nodes. A first cell transmission rate value written in the explicit cell rate field of the RM cell transmitted by the first end-node is stored at a control unit provided on the ATM network, and a second cell transmission rate value written in the explicit cell rate field of the RM cell returned by the second end-node is detected at the control unit. When the second cell transmission rate value is larger than the first cell transmission rate value, the second cell transmission rate value is rewritten into the first cell transmission rate value in the explicit cell rate field of the RM cell returned by the second end-node at the control unit.

摘要： In an asynchronous transfer mode switched network, a source terminal sends a burst of data cells and a control cell at periodic intervals through network nodes to a destination terminal. Each network node includes a first buffer and a second buffer, and incoming data cells are stored into the first buffer and incoming control cells are stored into the second buffer. A transmit controller is connected to the first and second buffers for forwarding cells in the first and second buffers in a downstream direction with priority given to the control cells in the second buffer over the data cells in the first buffer. A congestion detector is connected to the first buffer for writing a congestion indication into a control cell which is either stored in or forwarded from the second buffer when the first buffer is filled to a predetermined storage level. The destination terminal copies the congestion indication on receiving a control cell from the network and returns a control cell that contains the copied congestion indication toward the source terminal. On receiving a control cell containing the copied congestion indication, the source terminal reduces the data cell transmission rate.
