摘要： A system is provided for controlling the flow of data-packet traffic through an Ethernet telecommunications network having a multiplicity of nodes interconnected by multiple network links. Incoming data-packet traffic from multiple customer connections are received at a first node for entry into the network via the first node. Flow control messages are generated to represent the states of the first node and, optionally, one or more network nodes upstream from the first node, and these states are used as factors in controlling the rate at which the incoming packets are admitted to the network. Alternatively, the flow control messages may be used to control the rate at which packets generated by a client application are transmitted to the first node.

摘要： A method of testing a service connection within a container in an Ethernet network comprises coupling a test device to a port on a node in a path that includes the container, switching traffic of the service connection to the port, measuring selected parameters of the switched traffic in the test device, and using the measured parameters to evaluate the performance of the service connection. In one implementation, the switching uses service and container identifications, and switching the traffic to the test device is based on the service and container identifications. The test device may be capable of inserting traffic within the service connection, and the container may be a tunnel.

摘要： In a connection oriented communications network such as an asynchronous transfer mode (ATM) network, virtual circuit (VC) connections are aggregated onto virtual path (VP) connections to simplify traffic management through core switching elements. This invention provides a system and a method of introducing network level fairness between VP connections in the core. Resource management (RM) cells are used to import relevant traffic weighting parameters from the VC/VP aggregation point to the VP switching element. The weighting parameters are used by a queuing scheme at each switching function to introduce a fairness level component to each VP.

摘要： A method and system for detecting and controlling congestion in a multi-port shared memory switch in a communications network. The proposed congestion management scheme implements a local and a global congestion monitoring process. The local monitoring process monitors the queue depth. When the queue depth for any queue exceeds a queue length threshold a congestion control mechanism is implemented to limit incoming data traffic destined for that queue. Additionally, the global congestion monitoring process monitors the shared memory buffer and if the traffic thereto exceeds a shared memory buffer threshold a congestion control mechanism limits incoming traffic destined for any output queue which has been exceeding a fair share threshold value.

摘要： There is provided a method for transmitting non-real time traffic in a connection oriented communications network. The network includes a network core that has a source and a destination with a path between them. The non-real time traffic is received at the source from a number of connections and each of the connections is associated with one of many classes of transmission service. The method includes the first step of aggregating at the source the non-real time traffic received from the connections onto the path. The non-real time traffic is transmitted on the path without regard to the connections with which the non-real time traffic is associated. The method includes the second step of segregating at the destination the non-real time traffic so transmitted on the path within the core according to the corresponding connections with which the non-real time traffic is associated. Flow control is applied between the source and the destination to thereby regulate the rate of transmission of the non-real time traffic along the path.
