摘要： A bandwidth conserving queue manager for a FIFO buffer is provided, preferably on an ASIC chip and preferably including separate DRAM storage that maintains a FIFO queue which can extend beyond the data storage space of the FIFO buffer to provide additional data storage space as needed. FIFO buffers are used on the ASIC chip to store and retrieve multiple queue entries. As long as the total size of the queue does not exceed the storage available in the buffers, no additional data storage is needed. However, when some predetermined amount of the buffer storage space in the FIFO buffers is exceeded, data are written to and read from the additional data storage, and preferably in packets which are of optimum size for maintaining peak performance of the data storage device and which are written to the data storage device in such a way that they are queued in a first-in, first-out (FIFO) sequence of addresses. Preferably, the data are written to and are read from the DRAM in burst mode.

摘要： A method and system for queueing data within a data storage device including a set of storage blocks each having an address, a pointer field, and a data field. This set of storage blocks comprises a linked list of associated storage blocks and also a free pool of available storage blocks. The storage device further includes a tail register for tracking an empty tail block from which a data object is enqueued into the linked list. A request to enqueue a data object into the linked list is received within the data storage system. In response to the data enqueue request, an available storage block from the free pool is selected and associated with the tail register. A single write operation is then required to write the data object into the data field of a current tail block and to write the address of the selected storage block into the pointer field of the current tail block, such that the selected storage block becomes a new tail block to which the tail register points.

摘要： The ability of network processors to move data to and from dynamic random access memory (DRAM) chips used in computer systems is enhanced in several respects. In one aspect of the invention, two double data rate DRAMS are used in parallel to double the bandwidth for increased throughput of data. The movement of data is further improved by setting 4 banks of full ‘read’ and 4 banks of full ‘write’ by the network processor for every repetition of the DRAM time clock. A scheme for randomized ‘read’ and ‘write’ access by the network processor is disclosed. This scheme is particularly applicable to networks such as Ethernet that utilize variable frame sizes.

摘要： Novel data structures, methods and apparatus for finding a full match between a search pattern and a pattern stored in a leaf of the search tree. A key is input, a hash function is performed on the key, a direct table (DT) is accessed, and a tree is walked through pattern search control blocks (PSCBs) until reaching a leaf. The search mechanism uses a set of data structures that can be located in a few registers and regular memory, and then used to build a Patricia tree structure that can be manipulated by a relatively simple hardware macro. Both keys and corresponding information needed for retrieval are stored in the Patricia tree structure. The hash function provides an n->n mapping of the bits of the key to the bits of the hash key. The data structure that is used to store the hash key and the related information in the tree is called a leaf. Each leaf corresponds to a single key that matches exactly with the input key. The leaf contains the key as well as additional information. The length of the leaf is programmable, as is the length of the key. The leaf is stored in random access memory and is implemented as a single memory entry. If the key is located in the direct table then it is called a direct leaf.

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： A system and method of moving information units from a network processor 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 stored priorities associated with the various sources of the information units. The priorities in the preferred embodiment include a low latency service, a minimum bandwidth, a weighted fair queueing and a system for preventing a user from continuing to exceed his service levels over an extended period. The present invention includes a plurality of calendars with different service rates to allow a user to select the service rate which he desires. If a customer has chosen a high bandwidth for service, the customer will be included in a calendar which is serviced more often than if the customer has chosen a lower bandwidth.
