  • Automatic load balancing in switch fabrics
    Patent number: 7161901
    Abstract: A load balancing system and method for network nodes is provided. The load balancing system includes crossbar devices, queues to receive data and a load balancer. The load balancer determines the amount of data in each of the queues and sends data to specific crossbar devices based on the amount of data in each queue. The queues include a high priority queue and a number of non-high priority queues.
    Type: Grant

  • Scalable clock distribution for multiple CRU on the same chip
    Patent number: 6990162
    Abstract: A scalable clock recovery system. In one embodiment the system comprises a clock master unit, a clock distribution network, and a plurality of clock recovery units. The master clock unit generates a plurality of master clock signals, which are received by the clock recovery units. The clock recovery units use multiple stages of mixing to generate a recovered clock. The recovered clock can be used to recover data from a serial data stream.
