    摘要： Protection systems and methods for electronic devices including at least one communication line interface are disclosed. A switch connected to each interface and a working communication path in an electronic device is adapted for connection to a protection communication path and controllable to connect each interface to either the working communication path or the protection communication path. Inter-device messaging provides for switch control by a protection device connected to the protection communication path, monitoring of devices in a protection group, protection communication path monitoring, and automatic configuration of a protection group.

    摘要： One or more multiport systems are used to facilitate servicing of asynchronous communications events. A multiport system, such as an open collector multiport system, receives from one of a plurality of source components an asynchronous communications event directed to a target component coupled to the plurality of source components. The multiport system is controlled to provide, at any given time, a communications path between a plurality of ports of the multiport system to service the asynchronous communications event. One or more multiport systems are used to forward the event from the source to the target.

    摘要： A network relay apparatus which conducts data transfer by using a plurality of network LSIs includes a transfer engine unit having at least two network LSIs and a central control unit which controls the operation state of the network relay apparatus. The transfer engine unit includes the network LSIs capable of changing over at least one of a clock and an operation which differ every function block, a load judgment unit for judging a load laid upon each of function blocks in the network LSI, and a frequency voltage control unit for individually changing over at least one of the clock and operation voltage supplied to each function block on the basis of the load judged by the load judgment unit.

    摘要： A method and apparatus retrieves and stores configuration information for network endpoint devices from other devices in the network, such as a switch adjacent to the endpoint device. When the endpoint device establishes a connection with the network, it generates a sequence of SNMP getnext commands using the ILMI interface to obtain the configuration information from the network device. If the network device sends a trap to the endpoint device indicating a change has been made to the configuration parameters stored in the network device for a PVC, a series of SNMP getrequest commands are made using the ILMI interface to retrieve the configuration information for that PVC from the network device. If the endpoint device detects an interruption in communication with the network device, the endpoint device discards the information retrieved previously.

    摘要： A switch fabric implemented on a chip includes an array of cells and an I/O interface in communication with the array of cells for permitting exchange of data packets between said array of cells and components external to said array of cells. Each cell communicates with at least one other cell of the array, thereby permitting an exchange of data packets to take place between the cells of the array. Each cell includes a memory for receiving a data packet from another cell of the array as well as a control entity to control release of a data packet toward a selected destination cell of the array at least in part on a basis of a degree of occupancy of the memory in the destination cell. In this way, scheduling is distributed amongst the cells of the switch fabric.
