    摘要: The network device is described that comprises an allocator to adaptively allocate respective event message rate limits to client network devices that is in communication with an event-based system logging server to send event messages to the logging server for processing. The adaptively allocated event message rate limits are communicated to the client network devices so that limiting of a global rate of event messages received by the logging server comprises limiting the respective rates at which the client network devices can transmit event messages to the logging server. Measurement of respective event message rates comprises a count of event messages actually received by the logging server from the corresponding client device within a defined time window.

    摘要: A method for fast tracking and jitter improvement in an asynchronous sample rate conversion includes a digital phase locked loop (DPLL) for an asynchronous sample rate conversion (ASRC) device. A control apparatus in the DPLL includes a gain controller that sets and maintains gains (Ki, Kp) of two branches of the control apparatus at a fixed value, which enables searching of a desired value by the DPLL to determine a neighborhood of the desired value, and reduces the gains when the number of samples reaches a predetermined number. Processing units in the DPLL generate and process first and second input signals based on an input clock, an output clock, and a system clock. The second input signal is processed using two branches. Signals resulting from the two branches are re-aligned according to a changed status of the first processed input signal such that the signals resulting from the two branches are sampled in the same input clock interval.
