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.

摘要： An improved computer system may include a controller including a computer processor. The system may also include a selector apparatus in communication with the controller to choose a table having a higher collision quality index than other tables under consideration by the selector apparatus. The system may further include an exchanger apparatus to configure a standby table that replaces the table chosen by the selector apparatus. The system may additionally include a switch that changes a hash function based upon the exchanger apparatus′ replacement of the chosen table to enable the controller to reduce insertion times and/or collisions when interfacing with new components introduced to the controller.
