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： A method is disclosed for traffic policing in packet-based, broadband networks, such as ATM networks. The method comprises the steps of monitoring the arrival of incoming cells, and advancing a reference clock on a step of I if an arrival is late but not later than I, where I is an increment, and if an arrival is later than I assuming a new busy period and setting the reference clock at the arrival time.

摘要： In a method of fair queue servicing at a queuing point in a multi-service class packet switched network, incoming packets are received in buffers and outgoing packets are scheduled by a weighted fair queue scheduler. Real-time information of buffer usage along with the minimum bandwidth requirement is used to dynamically modify the weights of the weighted fair queue scheduler.

摘要： The method of the invention includes the step of transmitting a priority indicator containing information indicating the priority of network traffic over a connection to a downstream node in a communications network. The downstream node has a queue for queuing traffic received over the connection and the queue has an adjustable discard range. After transmitting the priority indicator, the network traffic is transmitted over the connection. When the priority indicator is received at the downstream node the discard range is adjusted to correspond to the priority indicated in the priority indicator. At the downstream node the network traffic is stored in the queue if a queue congestion measure is outside the discard range and discarded if the queue congestion measure is within the discard range. The priority indicator may be a Resource Management cell or may be provided in the header of a cell carrying the network traffic.

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： 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.

摘要： The method and system for buffering packets such as ATM cells at a queueing point of a device which employs a connection-orientated communications protocol includes the steps of logically partitioning a memory into plural reserved buffer spaces allocated to traffic classes and a shared buffer space available to any connection; determining whether to store or discard a given packet based on predetermined discard criteria; and filling the reserved buffer space to a predetermined state of congestion before storing the given packet in the shared buffer space. Reserved buffer space congestion states are defined with respect to individual connections, groups of connections, and the total capacity of the reserved buffer space itself. Packets are discarded when any, or alternatively a specific combination, of corresponding congestion states occur, and the shared space is congested as well. The system facilitates the balance between the sharing of physical memory resources amongst distinct and various types of traffic flows and the logical isolation thereof.

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.
