    摘要： In one embodiment, active links are added to, and removed from, a multichassis link bundle with one side of the multichassis link bundle terminated on multiple devices of a multichassis device. In one embodiment, adding active links includes selecting which particular device to which to add an active link to the multichassis link bundle based on a device priority of each of the multiple devices, with a device priority of a given device being based on a current number of active links associated with the given device.

    摘要： Throughput of a high-volume throughput-centric computer system is controlled by dynamically adjusting a concurrency level of a plurality of events being processed in a computer system to meet a predetermined target for utilization of one or more resources of a computer system. The predetermined target is less than 100% utilization of said one or more resources. The adjusted concurrency level is validated using one or more queuing models to check that said predetermined target is being met. Parameters are configured for adjusting the concurrency level. The parameters are configured so that said one or more resources are shared with one or more external programs. A statistical algorithm is established that minimizes total number of samples collected. The samples may be used to measure performance used to further dynamically adjust the concurrency level. A dynamic thread sleeping method is designed to handle systems that need only a very small number of threads to saturate bottleneck resources and hence are sensitive to concurrency level changes.
