    摘要： A network device including an ingress processor and egress processor which receives frames of data over the network on an input port, and transfers it to an appropriate output port. The received frame is processed by an ingress processor which prepares an intra-switch frame for delivery to an egress processor serving a relevant output port of the switch. The intra-switch frame includes a frame header having parameters which have been determined by the ingress processor, as well as data indicating an address for the egress processor for beginning processing of the frame. By identifying to the egress processor processing which has already taken place, the egress processor is relieved of any redundant processing of the frame. The egress processor provides a hardware frame classifier which decodes the information contained in the intra-frame header to derive parameters which have been previously computed as well as a starting address for the egress processor. By reducing the amount of redundant processing of the egress processor, total device throughput delay is reduced.

    摘要： The transport protocol for communicating between general purpose processors acting as contact points and network processors in a packet processing environment such as Ethernet is provided. In such an environment, there is at least one single control point processor (CP) and a plurality of network processors (NP), sometimes referred to as blades. A typical system could contain two to sixteen network processors, and each network processor connects to a plurality of devices which communicate with each other over a network transport, such as Ethernet. The CP typically controls the functionality and the functioning of the network processors to function in a way that connects one end user with another, whether or not the end user is on the same network processor or a different network processor. There are three types of communication provided; first, there is communication generally referred to as control services and normally there will be only one pico processor which operates as a GCH (guided cell handler) and only one that operates as a guided tree handler (GTH). A path is provided for the controls to the GCH and the GTH commands, and a separate path is provided for the data frames between the GDH's (general data handler) and the CP.

    摘要： A method and system for systematically accessing and monitoring operating parameter signals within an IC device. A probe configuration logic selects a subset of signals from among a set of available signals within a physical or logical subdivision of the IC device. Signal access logic selectively provides physical or logical access from the selected subset of signals within the physical or logical subdivision of the IC device to a probe sensor, such that IC device operations may be flexibly and comprehensively monitored. A local mode selector provides remote access to the selected subset of signals at an input/output (I/O) data interface. Data packaging logic in communication with the probe sensor permits port mirroring of the I/O data interface.

    摘要： A method for integrating Asynchronous Transfer Mode (ATM) and frame-based traffic flows within a telecommunications network is disclosed. The telecommunications network includes a network processor having upside processing means for delivering an incoming flow from the telecommunications network to a switch and downside processing means for delivering outgoing network traffic from the switch to the telecommunications network. The incoming flow is initially received at the upside processing means as a frame-based flow. The incoming flow may be characterized as belonging to a group having frame-based flows and ATM flows. In response to the receipt of the incoming flow, the incoming flow is determined if it is destined for a legacy, ATM-only device. The incoming flow is then processed according to the determined routing requirements and the incoming flow characterization before delivering the incoming flow to the switch.
