    摘要： A multicast processor minimizes the software resource needed to process multicast protocol and broadcast protocol for bridges and routers in a network processor based environment. The multicast forwarding processor receives multicast and broadcast Layer 2/Layer 3/Layer 4 (L2/L3/L4) frames from a network processor. During reception, a frame layer flag, a unicast/multicast flag, and a frame position flag are set. A multitask forwarding table is accessed, and the frame, unicast/multicast, and frame position flags are stored and updated. The frame, unicast/multicast, and frame position flags are then sent to a frame forwarding processor. The L2/L3/L4 frames are routed to an L2 learning processor. The L2/L3/L4 frames are received from the frame forwarding processor, and the L2/L3/L4 frames are sent to an L3/L4 processor for frame header modification. The modified L2/L3/L4 frames are received from said L3/L4 processor, and the modified L2/L3/L4 frames are sent to an L2 filter processor.

    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.

    摘要： A controllable mechanism for by-passing Layer 4 (L4) classification is based on the insertion into a set of MAC rules in SA MAC lookup means a set of Layer 4 (L4) Skip Classification Flags. Routing is accomplished by selecting which rule to apply to the packet and reading the state of the corresponding L4 Skip Classification Flag. In response to a first state of said corresponding L4 Skip Classification Flag, performing an L4 classification followed by a routing of the data packet. In response to a second state of said corresponding L4 Skip Classification Flag, reading the state of a Global Classification Flag. In response to a first state of said Global Classification Flag, performing an L4 classification followed by a routing of said data packet. In response to a second state of said Global Classification Flag performing a routing of the data packet. The L4 Skip option change does not use the option change of reading the L4 Skip Classification Flag from the port table, whereas the second embodiment uses this option. The third and fourth embodiments are similar to the first and second embodiments but with the. addition of inserting into a set of Layer 3 (L3) rules in L3 lookup means a set of Layer 4 (L4) Classification Required Flags. The third embodiment does not use the option of reading the L4 Skip Classification Flag from the port table, whereas the fourth embodiment uses this option.

    摘要： A method and system for providing remote procedure calls in a multiprocessing system is disclosed. The multiprocessing system includes a general purpose processor and a plurality of network processors. Each of the plurality of network processors includes a memory. The method and system comprises accessing a reserved address in at least one of the network processors and initiating a software action by a first portion of the reserved address. The method and system further includes pointing to an address within the memory of the at least one network processor to be processed based upon data in a second portion of the reserved address, wherein the data at the address is processed. A system and method in accordance with the present invention provides an indirect software jump in a microprocessing system through providing a reserved address in memory of each of the reserved address includes two portions. A first portion of the address triggers the software event requested by the general purpose processor (for example) and a second portion of the reserved address is utilized to process the data that was loaded at that address in the processor. The indirect software jump allows a general purpose processor to execute software on a network processor indirectly for custom application services or debug operations.
