    摘要： A method and system for identifying a data structure associated with a packet of data. A processor internal to a packet processor may extract one or more fields in a packet header field of a received packet of data to generate a search key. The internal processor may then be configured to select which table, e.g., routing table, quality of service table, filter table, needs to be accessed using the search key in order to process the received packet of data. A determination may then be made by the internal processor as to whether a CAM or a hash table and a Patricia Tree are used to identify the data structure associated with the received packet of data. Based on table definitions in a register, the internal processor may make such a determination.

    摘要： The present invention relates to a method and system for storing a plurality of multi-field classification rules in a computer system. Each multi-field classification rule includes a rule specification that itself includes a plurality of fields and a plurality of field definitions corresponding to the fields. The method of the present invention includes providing a virtual rule table, where the table stores a plurality of field definitions, and for each of the plurality of multi-field classification rules, compressing the rule specification by replacing at least one field definition with an associated index into the virtual rule table. The method also includes storing each of the compressed rule specifications and the virtual rule table in a shared segment of memory.

    摘要： A network processor utilizes protocol processor units (PPUs) to provide instruction communication for the network. Each PPU includes a core language processor (CLP). Each CLP contains general purpose registers and includes a coprocessor that contains scalar registers and array registers. The CLP controls and instructs a plurality of coprocessors that run in parallel with the CLP. Each coprocessor is a specialized hardware assist engine having direct access to the CLP registers and arrays through two sets of interface signals, a coprocessor execution interface and a coprocessor data interface.

    摘要： A procedure is used to provide data structures that handle large numbers of active data entries and a high rate of additions and deletions of active entries. The procedure utilizes one or more of the following modifications. Timers are removed from individual session table entries and are linked via pointers. Bilateral links are established between the session table and the timer structure. Aging/timer checks are applied to the timer control block (TCB). A chain of TCBs, optionally including an excess of blocks, may be used along with packing of multiple TCBs into a single memory location. This excess of blocks permits a terminated session to continue to occupy a TCB until the timer process progresses to that block location in the chain of blocks.

    摘要： A mechanism controls a multi-thread processor so that when a first thread encounters a latency event for a first predefined time interval temporary control is transferred to an alternate execution thread for duration of the first predefined time interval and then back to the original thread. The mechanism grants full control to the alternate execution thread when a latency event for a second predefined time interval is encountered. The first predefined time interval is termed short latency event whereas the second time interval is termed long latency event.

    摘要： Dynamic data search structures are described that are capable of handling large numbers of active entries and a high rate of additions and deletions of active entries while complying with 2MSL requirements and providing precise time-out capabilities. A free queue which is integrated with the timing loop of session entries provides available sessions for new entries in the search structure and removes obsolete sessions from the tree. Multiples of such timing loops can be used to maintain multiple timing intervals. One such timing loop may contain soft entries still attached to the search structure but which are eligible to be removed and to be reused to accommodate new sessions. A spare buffer pool is also included in the data structure to add and remove buffers to maintain delays.
