摘要： A system and method of protocol and frame classification in a system for data processing is disclosed, including, analyzing a portion of the, packet or frame according to predetermined tests, and storing characteristics of the packet for use in subsequent processing of the frame. The characteristics are preferably obtained with hardware, which does so quickly and in a uniform time period. The stored characteristics of the packet are then used by the network processing complexes in further processing of the frame. The processor is preconditioned with a starting instruction address or cede entry point and the location of the beginning of the layer 3 header as well as flags for the type of frame.

摘要： A design structure is provided for a slotted ring network, in which a node may transmit a non-renewable slot reservation with any unreserved slot. The reservation restricts other nodes from transmitting a new packet in the slot. When the slot returns around the ring to the reserving node, the slot will be available. Preferably, reservation is made responsive to a starvation condition in the reserving node, which may be detected in any of various ways. In an optional enhancement, a reservation identifies the reserving node, and another node on the ring is free to transmit a new packet in the reserved slot if the new packet will reach its destination at or before the reserving node, and thus will not interfere with the reservation.

摘要： A system and method of moving information units from an output flow control toward a data transmission network in a prioritized sequence which accommodates several different levels of service. The present invention includes a method and system for scheduling the egress of processed information units (or frames) from a network processing unit according to service based on a weighted fair queue where position in the queue is adjusted after each service based on a weight factor and the length of frame, a process which provides a method for and system of interaction between different calendar types is used to provide minimum bandwidth, best effort bandwidth, weighted fair queuing service, best effort peak bandwidth, and maximum burst size specifications. The present invention permits different combinations of service that can be used to create different QoS specifications. The “base” services which are offered to a customer in the example described in this patent application are minimum bandwidth, best effort, peak and maximum burst size (or MBS), which may be combined as desired. For example, a user could specify minimum bandwidth plus best effort additional bandwidth and the system would provide this capability by putting the flow queue in both the NLS and WFQ calendar. The system includes tests when a flow queue is in multiple calendars to determine when it must come out.

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 system and method of protocol and frame classification in a system for data processing (e.g., switching or routing data packets or frames). The present invention includes analyzing a portion of the packet or frame according to predetermined tests, then storing key characteristics of the packet for use in subsequent processing of the frame. The key characteristics for the frame (or input information unit, such as the type of layer 3 protocol used in the frame, the layer 2 encapsulation technique, the starting instruction address and flags indicating whether the frame uses a virtual local area network, preferably using hardware to quickly and in a uniform time period. The stored key characteristics of the packet are then used by the network processing complexes in its further processing of the frame. The processor is preconditioned with a starting instruction address and the location of the beginning of the layer 3 header as well as flags for the type of frame. That is, the instruction address or code entry point is used by the processor to start processing for a frame at the right place, based on the type of frame. Additionally, additional instruction addresses can be stacked and used sequentially at branches to avoid additional tests and branching instructions.

摘要： Method and apparatus for segmenting variable length frames into fixed length cells in a network equipment. The method allows preparing information to build the cells resulting in the segmenting of a succession of frames directed to the same destination in said network equipment. The cell may be packed with more than one frame. The cell information comprises the address where to read the frame data in a first storage unit, the cell header itself which indicates if the cell includes data from one packet or for more packets, a pointer per each of said more packets, designating the place of the end of data of the previous packet in the cell and a cell type field indicating one of the following types: a start of a new frame type, a continuation of frame type, a end of current frame type and a start and a end of a new frame type. The segmenting apparatus comprises a finite state machine using an Add/substract unit to compute the cell information and write said cell information in a second storage unit.
