摘要： Techniques are provided for hash-based routing table management in a distributed network switch. A frame having a source address and a destination address is received. If no routing entry for the source address is found in a routing table of a switch module in the distributed network switch, where the routing table is divided into slices of buckets, then routing information is determined for the source address and a routing entry is generated. The routing table is modified to include the routing entry and based on a set of hash functions and properties of the slices.

摘要： A multi-module switching system comprising at least two switching modules adapted for receiving data packets from at least one input adapter and transmitting the data packets to at least one output adapter, each of the switching modules including a shared buffer for buffering a portion of a data packet received from an input adapter and transmitting the portion to an output adapter. One of the switching modules is a master module receiving a portion of a data packet containing a packet header and sending control information contained therein serially to each other switching module as a slave module. Each slave module includes a delay computing structure adapted for computing a delay needed to transmit the control information from the master module to this slave module and a first storing structure adapted for storing a portion of a data packet transmitted from an input adapter to the slave module during the delay, before transmitting the portion to a respective shared buffer such that the portion of data packet is not received by the shared buffer before the slave module has received the control information from the master module.

摘要： A line-adapter of a communications controller includes, for scanning the teleprocessing lines connected to it, cyclic scanning means FES exchanging information with the lines through a serial bidirectional link on which data and control informations are partitioned into frames and slots. Since both the FES and the serial link work with their own timings, an interface FESA is provided to adapt the FES scanning to the serial link structure. This FESA includes temporary storage means for storing on the one hand, data and control information transmitted from the LICs to the FES (10) through the inbound serial link, and on the other hand, data and control information transmitted from the FES to the LICs through the outbound serial link. The access of the FES, the outbound and inbound serial link to the storage means is time-shared and granted by an arbitration logic, according to the relative priorities of operation of said elements within the line-adapter of the communications controller.

摘要： Techniques are provided for routing table synchronization for a distributed network switch. In one embodiment, a first frame having a source address and a destination address is received. If no routing entry for the source address is found in a routing table of a first switch module, routing information is determined for the source address and a routing entry is generated. An indication is sent to a second switch module, to request a routing entry for the source address to be generated in the second switch module, based on the routing information.

摘要： Techniques are provided for cached routing table management in a distributed network switch. A frame having a source address and a destination address is received. If no routing entry for the source address is found in a routing table of a switch module in the distributed network switch, then routing information is determined for the source address and a routing entry is generated. The routing table is modified to include the routing entry, based on a set of hash functions. Upon accessing the generated routing entry in the modified routing table responsive to a subsequent lookup request for the source address, the set of caches is modified to include the generated routing entry.

摘要： Techniques are provided for hash-based routing table management in a distributed network switch. A frame having a source address and a destination address is received by a switch module having bridge elements and a routing table divided into slices of buckets, each slice having a respective property and including one or more buckets. If a routing entry for the source address is found in a first slice of a first set of buckets of the routing table responsive to a lookup request for the source address, and the property of the first slice satisfies a replication condition, then the routing entry is replicated to a second set of buckets of the routing table.

摘要： An improved computer system that can include a controller having a computer processor, the controller to reduce insertion times and/or collisions when interfacing with new components introduced to the controller. The system may also include a collision avoidance apparatus that reduces hashing collisions by using a plurality of tables and a plurality of keys per bucket. The system may further include a hash apparatus in communication with the controller to map the plurality of keys to the plurality of tables where the hash apparatus uses a single hash logic to provide an avalanche effect when one key is changed which results in nearly half of bits changing in the plurality of tables.

摘要： A queue scheduling mechanism in a data packet transmission system, the data packet transmission system including a transmission device for transmitting data packets, a reception device for receiving the data packets, a set of queue devices respectively associated with a set of priorities each defined by a priority rank for storing each data packet transmitted by the transmission device into the queue device corresponding to its priority rank, and a queue scheduler for reading, at each packet cycle, a packet in one of the queue devices determined by a normal priority preemption algorithm. The queue scheduling mechanism includes a credit device that provides at each packet cycle a value N defining the priority rank to be considered by the queue scheduler whereby a data packet is read by the queue scheduler from the queue device corresponding to the priority N instead of the queue device determined by the normal priority preemption algorithm.
