System and method for hybrid contention/polling protocol collison resolution used backoff timers with polling

摘要

The system and method provide for efficiently resolving collisions in an environment where a transmitting device cannot hear collisions without a headend control station/control device, i.e., master, repeating transmission of all upstream frames in the downstream direction. This invention also prevents additional collisions from occurring between a device that is retransmitting and a device that is transmitting a packet for the first time. Further, the present invention allows continued utilization of a channel by other devices while contending devices are processing collision resolution procedures.
