    Abstract: Novel data structures, methods and apparatus for a Software Managed Tree (SMT) which provides a mechanism to create tree structures that follow a search mechanism defined by a control point processor. The search mechanism does not require storage on the previous pointer and uses only a forward pointer along with a next bit or group of bits to test thereby reducing storage space for nodes. The search mechanism processes multiple filter rules for an application without requiring multiple searches and also allows various filter rules to be chained. Two patterns of the same length are stored in each leaf to define a range compare. A compare at the end operation is either a compare under range or a compare under mask. In a compare under range, the input key is checked to determine if it is in the range defined by the two patterns. In a compare under mask, the bits in the input key are compared with the bits in a first leaf pattern under a mask specified in a second leaf pattern.

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: An improved method and system for generating a frame check sequence. A multiple-bit data string, M, is received in which M is of the form: anbncndnan−1bn−1cn−1dn−1 . . . a2b2c2d2a1b1c1d1. M is thereafter parsed into multiple subframes of the form: anan−1an−2 . . . a2a1; bnbn−1bn−2 . . . b2b1; cncn−1cn−2 . . . c2c1; and dndn−1dn−2 . . . d2d1. The subframes are padded with zeros resulting in subframes of the form: an000an−1000an−2000 . . . a2000a1000; 0bn000bn−1000bn−200 . . . 0b2000b100; 00cn000cn−1000cn−20 . . . 00c2000c100; and 000dn000dn−1000dn−2 . . . 000d2000d1. A partial check sum is then generated for each of the multiple subframes. Finally, each of the partial check sums are added together such that a frame check sequence for M is obtained.
