Abstract
A switch according to the present invention can have a number of ports in an ASIC greater than the ASIC clock speed divided by the network protocol rate. The switch ASIC contains multiple blocks, each block having a number of ports equal to the ASIC clock speed divided the packet rate of the protocol. Each block has a number of queues equal to the total number of ports on the ASIC to receive packets. The queues are scheduled from each block into a number of outputs equal to the number of blocks. The outputs of each block are received by a scheduler which evaluates the packets available at the outputs of each block to determine the combination of outputs which provides the most connections that are ready for transmission. The combination with the most connections is then utilized to provide packets to the egress section of each block.
