摘要： A network device for use in a data communication network comprises: a multiplicity of ports capable of receiving input data; a common buffer memory for storing in respective buffers data received by the input ports; and processing system for controlling the writing of data into buffers and the reading of data from said buffers. The processing system determines whether the extent of occupation of the common buffer memory exceeds a threshold defined to represent congestion of the memory. Counter system enabled by the processing system on detection of the aforementioned threshold count units of input data through the respective ports, the processing system decrementing these counters as data is read out from the common buffer memory.

摘要： In one embodiment, a method is described for detecting an operational failure between the network unit and an adjacent network unit in the stack; controlling the switching engine to redirect packets which would otherwise be sent from a particular port to the adjacent network unit to be forwarded from another port to be sent to a different network unit in the stack; and entering the switching engine into a bypass mode in response to control data indicating an operational failure between at least two other network units in the stack to cause packets to be forwarded without being re-directed by the switching engine.

The network unit has at least one fabric port for connection to a partner port on another one of the units by at least one link. The network unit is organized to send and receive via the at least one fabric port protocol packets which contain information on the path costs between said units in the fabric and to perform an algorithm to determine, on the basis of said information, routes for data packets within the fabric to other units of the fabric.

摘要： A method of controlling access to a common physical data transmission link from a multiplicity members of a packet-based local area network, wherein the members are partitioned into a plurality of virtual local area networks (VLANs) and wherein packets are identified according to the virtual local area network from which they come, comprises (a) monitoring packet traffic from the virtual local area networks on the link and thereby obtaining measures of the traffic flow from each of the virtual local area networks; (b) determining whether the traffic flow for each respective VLAN is above or below a threshold; (c) denoting a VLAN which is above its threshold as in a restricted state and denoting a VLAN which is below its threshold as in a priority state; (d) arbitrating between requests from the VLANs to transmit data packets on the link; and (e) according priority in the arbitration to a VLAN which is in a priority state over any VLAN which is in a restricted state. A request to transmit is gated with a signal denoting the state of the respective VLAN to provide a set of priority requests. In response to the presence of any priority request the arbitration is made only in respect of the set of priority requests and in the absence of a priority request arbitration is made in respect of the VLANs which indicate a request to transmit. A ‘leaky bucket’ counter may be used for monitoring the traffic for each VLAN.

摘要： A method and processing device for controlling the communication of data associated with a user on a network 1 is described, in which the communication of data to and from a user is controlled according to user profile information. In a preferred embodiment, the user profile information is maintained in a database 9 accessible to processing devices 5 providing access to the network 1, and includes a volume allowance for a predetermined time period, a maximum transmission rate and current usage information for the user. Each time a user connects to the network 1, the method determines whether the user is within the volume allowance, and if so, permits access to the network 1. The communication of data is controlled according to the maximum transmission rate. The method may be implemented in software.

摘要： A data connection between two network stations such as an Ethernet hub and an end station which are both capable of exchanging data at the higher of two rates, the higher rate being selected by an auto-negotiation process, is monitored for the occurrence of error represented by a symbol representing the start of a data packet immediately followed by an idle symbol. The rate of occurrence of such errors is compared against a threshold and the speed of the data connection is downgraded to the lower rate.

摘要： A search apparatus and method for establishing efficiently whether a particular number, eg a MAC address, is stored in a database, eg in a communications bridge. The search is conducted stepwise on the basis of portions of the number, until one or zero match is found in the database. In the event that one match is found, a final confirmation is made that the whole of the number located and the number searched for are the same. This provides an efficient way to search among a subset of possible very large numbers.
