摘要： An apparatus and method for enabling the combination of multiple streams of data cells into a single thread. By enabling plural input ports of an intermediate device to access a single parallel output port of the device, plural network switch elements share a single thread through a switch fabric. For instance, the method and apparatus permit interleaving the relatively low bandwidth cell outputs of two ATM network switch central control processors onto a single thread routed through an interconnected switch fabric. Certain of these cells are received from the switch fabric at a parallel input of the intermediate device, then routed to one of plural serial output ports. Pacing of cells provided to the plural serial input ports prevents exceeding the shared thread bandwidth.

摘要： A method and apparatus for performing virtual connection merging in an output port of a network switch are disclosed. In the event no completely assembled packets have been received and scheduled for transmission, a partially received packet is selected for cut-through transmission prior to receipt of all cells comprising the packet. Transmission of the selected packet is initiated and a timer is started. If the timer expires prior to the receipt of an end of packet indication for the packet for which transmission has commenced, and end of packet signal is generated and transmitted and the transmission of additional cells for the cut-through packet is aborted. In this manner, delays associated with packet reassembly may be avoided and buffer sizes of reassembly buffers may be reduced.

摘要： The present invention is directed to an apparatus and method for efficiently transferring asynchronous transfer mode (ATM) cells across a backplane in a network switch. The present invention is realized through an electrical apparatus that converts parallel data that is received on parallel data input ports to serial data that is transmitted on serial data output ports. The parallel data that is received on each parallel data input port is divided and transmitted from a corresponding pair of serial data output ports. The electrical apparatus also converts serial data that is received on serial data input ports to parallel data that is transmitted on parallel data output ports. The serial data that is received on a corresponding pair of serial data input ports is combined and transmitted from a parallel data output port.

摘要： An apparatus and technique for facilitating mapping of a Multicast Circuit Identifier ("MID") to a Local Circuit Identifiers ("CID") is disclosed. Table entries for such mapping can be disposed in non-contiguous memory locations. A pointer is employed in ca h entry to indicate the location of any subsequent memory location associated with the MID. CIDs and associated memory locations are allocated only for ports that participate in a connection. To implement the apparatus and technique a first table provides an index into a second table based upon the MID. The second table includes entries having a port identification field, a pointer field and a CID field. The CID field indicates the CID associated with the port indicated by the port identification field. The CID is written to the header of the copy of the cell to be transmitted to the indicated port. The pointer indicates further entries in the second table that are associated with other copies of the cell to be transmitted in the multicast connection, if such entries exist. The CID is employed to obtain a Virtual Path Identifier ("VPI") and Virtual Circuit Identifier ("VCI") from a third table.

摘要： Systems and methods for providing dynamic call models for users in an IMS network. A system and method provisions dynamic call models within an IMS network having a serving call state control function (S-CSCF) for providing session control for user endpoint (UE) devices. At least one user endpoint device (UE) with agent logic, expresses dynamic context of the UE in a message and sends said dynamic context message to a S-CSCF, wherein said dynamic context includes at least a subset of devices that could be used as UEs or associated devices, network connections that terminate or emanate from said devices that could be used as UEs or associated devices, and capabilities of said devices that could be used as UEs or associated devices. S-CSCF logic receives said context message from the UE and constructs a dynamic call model in response thereto, said dynamic call model having filter codes to associate IMS service codes with application servers (ASs) in communication with the IMS network, said ASs being responsive to service point triggers (SPTs) and each AS having service logic to provide a service for a corresponding IMS service code.

摘要： A massively-parallel computer includes a plurality of processing nodes and at least one control node interconnected by a network. The network faciliates the transfer of data among the processing nodes and of commands from the control node to the processing nodes. Each processing node includes an interface for transmitting data over, and receiving data and commands from, the network, at least one memory module for storing data, a node processor and an auxiliary processor. The node processor receives commands received by the interface and processes data in response thereto, in the process generating memory access requests for facilitating the retrieval of data from or storage of data in the memory module. The node processor further controlling the transfer of data over the network by the interface. The auxiliary processor is connected to the memory module and the node processor. In response to memory access requests from the node processor, the auxiliary processor performs a memory access operation to store data received from the node processor in the memory module, or to retrieve data from the memory module for transfer to the node processor. In response to auxiliary processing instructions from the node processor, the auxiliary processor performs data processing operations in connection with data in the memory module.

摘要： A data communications switch and method of operation are presently disclosed enabling flexible, selectable provision of a common timing signal for synchronized external communication through physical layer interfaces with other network devices, synchronized internal communications within the switch, and for uninterrupted synchronization of such communications. Synchronization of external communications is enabled by programmable selection from among plural potential timing references at redundant timing modules (TMs). An active TM provides a primary external synchronization clock; a standby TM provides a redundant timing function. Both TMs access the same references. A state signal indicates which synchronization clock is active. External interfaces derive timing from this distributed clock. Synchronized internal timing is provided by an internal clock and phase-locked loop (PLL) on each TM. The clock/PLL timing signal output is routed to other switch elements, enabling synchronized internal data transfer. Both interconnected TMs actively generate clock signals for external and internal use, enabling seamless timing switchover should conditions warrant a change in TMs.
