Abstract
Scheduling in a distributed data collection process is performed locally, within collectors. Scheduling of data transfers from endpoints or downstream collectors or to upstream collectors is based on local queues, without global management. Additionally, scheduling for the collector input queue, which manages data collection from endpoints or downstream collectors, is bifurcated from scheduling for the output queue, which manages notifications to upstream collector(s) regarding the availability of collection data for pickup. Such bifurcation permits simpler scheduling logic and different functional responses to similar events, and further localizes scheduling. Scheduling of collection data transfer is controlled, within parameters specified by the output scheduler for the endpoint or downstream collector, by the input queue for the upstream collector. Scheduling is thus based primarily on the portion of the data transfer mechanism mostly likely to comprise a bottle-neck, the upstream collector, but accommodates large numbers of fully parallel data generation endpoints as well as nondeterministic endpoint availability.
