Abstract:
1. A method for processing data streams, the method comprising: establishing a plurality of initial sample zones; establishing a plurality of wakeup zones; sampling a plurality of data packets by a processor based on the plurality of initial sample zones; estimating the traffic based on the sampling of the plurality of data packets; modifying the wakeup zones based on the estimated traffic; collecting traffic statistics based on the sampled data packets; and establishing modified estimated data zones based on the estimated traffic, wherein the wakeup zones are modified based on the modified estimated data zones, wherein the modifying wakeup zones comprises extending a start time of at least one wakeup zone to an earlier time in order to synchronize the start time of the at least one wakeup zone to the start time of a most recent sample zone that begins prior to a given data packet.
