    摘要： Methods, systems and computer program products are provided which control message storms in a network by classifying multiple destination messages into a plurality of broadcast message classes based upon characteristics of the broadcast messages. The number of multiple destination messages for each class of broadcast messages of the plurality of classes of broadcast messages are then counted so as to provide a plurality of broadcast message class counts. Multiple destination messages of a class of broadcast messages are then selectively transmitted based upon the broadcast message class count for the class of broadcast messages.

    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.
