ABSTRACT:
Systems are provided for sequencing, delivery acknowledgement, and throttling of data packets over a network layer, such as UDP and SMS. To support devices with limited battery resources, the invention incorporates asymmetric retry logic and/or acknowledgements with overlapping ranges, to minimize the transmissions required for the device. The sender of a data-bearing frame does not need to wait for a frame to be acknowledged before sending the next, such that many frames can be “in flight” at once.
