Abstract
A method of transmitting packets over a network includes steps of transmitting a first plurality of test packets during a first plurality of time locations that are coarsely spaced apart in time; determining which of the first plurality of time locations corresponds to favorable network traffic conditions; transmitting a second plurality of test packets over the network during a second plurality of time locations that are finely spaced apart in time, wherein the second plurality of time locations are selected on the basis of favorable network traffic conditions; determining which of the second plurality of time locations corresponds to favorable network traffic conditions; and transmitting data packets over the network using one or more favorable time locations determined by the finely spaced test packets. The method can be used to “zero in” on congested network periods by detecting differences in packet latencies among test packets.
