Abstract: A network device includes output rate control logic having variable bandwidth and a response time constant that increases according to an amount of time that an input rate of data to the network device is evaluated by the control logic.

Abstract: “A process of scheduling stream packets for output from a multiplexing network device involves prioritizing the output of packets first according to stream priority, and within a particular priority, by stream ID.

Abstract: A process involves controlling an output rate of a network device using rate control logic, and providing a variable bandwidth for the rate control logic and increasing a response time constant of the rate control logic according to an amount of time that an input rate of data to the network device is evaluated by the rate control logic; applying a rate estimate when a determination of the output rate to a predetermined accuracy is unavailable; applying a time rate determined from the difference in two PCR packets otherwise; and applying the time rate determined from the difference in two PCR packets unless the rate estimate shows that an actual rate has changed to an extent that triggers a change in the output rate to the rate estimate.

Abstract: A system includes logic to cache at least one block in at least one cache if the block has a popularity that compares favorably to the popularity of other blocks in the cache, where the popularity of the block is determined by reads of the block from persistent storage and reads of the block from the cache.

Abstract: A channel alignment system in an optical communication network includes logic to sample power of a quadrature amplitude modulation (QAM) channel at a component downstream from a QAM modulator. The system determines if the sampled channel power has a sufficient level. The system signals power control logic of the QAM modulator to adjust a gain of the sampled channel.

Abstract: A RAID storage system includes an outer stripe size that is an integer multiple J of a product of an inner stripe size and a number of data disks in a RAID disk set, where J is greater than one (1).
