Abstract
The present invention provides a system and method for utilizing the Advanced Switching network protocol to communicate over long distances, such as multiple kilometers. The present invention utilizes an existing status bit, referred to as the Perishable Bit, within the AS packet header, to reduce the number of packets which must be stored in the retry buffer. This reduces the required size of the retry buffer and simultaneously reduces the latency associated with retransmitting time critical packets after NAKs are received. The receiving device also utilizes the Perishable Bit in determining which packets to accept and which to discard.
