摘要： A method and system for reserving a virtual connection from a source workstation to a destination workstation. Packets of data are transmitted over a network between an ingress node of the source workstation and an egress node of the destination workstation. In accordance with the method of the present invention, a reservation request is delivered from the source workstation to a reservation server. The reservation server includes a user database for storing the identification of each user allowed to access to the reservation server and also stores the rights of each user. The reservation server further includes a network database for storing the information describing a network capacity required to set up the virtual connection. A verification is then performed to determine whether or not the reservation request may be validated in view of user information within said source workstation. A second verification is performed to determine whether or not the capacity of said network is sufficient to meet the requirements of the reservation request. In response to the capacity of the network being sufficient to meet the requirements of the reservation request, a virtual connection is established from the ingress node to the egress node.

摘要： The present invention relates to a method and system of sharing among a plurality of virtual channel connections the bandwidth of a bandwidth adjustable virtual path connection established between a source node and a destination node within a packet or cell switching network comprising a plurality of nodes interconnected with transmission links, said virtual channel connections comprising bandwidth adjustable reserved virtual channel connections with minimum bandwidth reservation and/or reserved virtual channel connections and/or non reserved virtual channel connections with minimum bandwidth reservation or/and totally non reserved connections without minimum bandwidth reservation. When the source node receives a notification indicating a new bandwidth to allocate to the bandwidth adjustable virtual path connection, and when this new bandwidth is lower than the sum of the current reserved bandwidth of virtual channel connections, the current reserved bandwidth of each bandwidth adjustable virtual channel connection is reduced by applying a ratio to the part of the current bandwidth reserved above the minimum reservation. The ratio is, in a preferred embodiment, proportional to the difference between the sum of the reserved bandwidth of all virtual channel connections and the new available bandwidth allocated to the bandwidth adjustable virtual path connection, and inversely proportional to the sum of the bandwidth reserved above the minimum reservation for the bandwidth adjustable virtual channel connections.

摘要： This system is made to perform congestion detection and flow control in high speed digital packet switching network (22) carrying discardable and non-discardable traffic. Forward traffic received at a destination system over a first connection from a source system is monitored. If a congestion-indicating bit is detected in a received packet, a backward congestion indicator is set in packets flowing from the destination system to the source system over a second connection. The source system integrates the number of backward congestion indicators received over successive periods of time using a count-up, count-down counter. Specific congestion control actions are taken at the source system as a function of the counter state at the end of each of the successive periods of time. The congestion control actions may include increasing or decreasing the bandwidth allocated to discardable traffic intended to be delivered over the first connection.

摘要： An explicit rate algorithm is disclosed for use in an end-to-end closed loop flow control algorithm for an ATM network which carries at least constant bit rate (CBR) traffic, variable bit rate (VBR) traffic and adjustable bit rate (ABR) traffic. The algorithm determines how much additional bandwidth is available for ABR traffic on an output link from a node and produces an explicit rate variable that can be forwarded to a source for the ABR traffic. Both the maximum and minimum bandwidths already reserved for all connections on the output link are determined. A single reserved bandwidth value is chosen within the range defined by the maximum and minimum reserved bandwidth values. The current utilization of the ABR input buffer for the node is also determined. The explicit rate variable is generated as a function of the link capacity, the reserved bandwidth value and the current utilization of the ABR input buffer. The explicit rate variable is written into a resource management cell which is routed through the network to the ABR traffic source. The explicit rate variable is intended to change the input rate of the ABR source to utilize more of the ABR input buffer.

摘要： A system for providing prioritized queue management within a data transmission network node that supports different types of data frame traffic is disclosed herein. The system includes a frame buffer for storing an incoming frame that has an identifiable frame type. A queue is pre-associated with the frame type of the incoming frame such that upon arrival of the frame at the network node, the queue stores a location address at which the frame is stored within the frame buffer such that the frame is maintained within the queue. The queue that contains the frame is stored within a frame table. Processing means are provided for determining a time at which the queue forwards the frame from the frame buffer in accordance with a pre-determined sub-queue priority list. The system further includes time metering means associated with the frame for temporally assigning the frame to a virtual sub-queue among multiple virtual sub-queues that are associated with the queue. The sub-queues are sequentially ordered according to the predetermined sub-queue priority list such that the processing means selects a highest priority frame for forwarding from the frame buffer.

The network comprises a plurality of switching nodes interconnected through a plurality of communication links. Each of the switching nodes comprises means for switching packets from at least one input link to at least one output link.

摘要： An improved access control system for a memory system in which memory locations can be allocated to virtual output queues dedicated to output ports from the system. The virtual queues can be used to handle data of different priorities. Thresholds are defined for the occupancy of the overall memory and of each virtual queue. The access control system regulates the acceptance of data stored in input adapters by determining whether a back pressure situation exists for the data's target output adapter for the class of traffic to which the data belongs. A single-bit access-controlling back pressure signal is generated as a function of the occupancy level of either the overall memory or of the virtual queue defined for the target output adapter.

摘要： Traffic congestion control is provided for a network node multiport switch capable of switching data packets of different priorities from input lines, via receive adapters, to output lines via transmit adapters. A spacing function is performed to limit the rate of data transfers through the switch in the absence of high priority data at the input lines and in the absence of a backpressure signal indicating the switch is congested at its output. If high priority data is detected or a backpressure signal has been generated, the data transfer rate is increased to deal with possible congestion.
