High priority voice and data packets transmitting method for Internet protocol transmission network, involves keeping bit in high priority packets protocol header at 1 and resuming low priority packet/packet fragment transmission

摘要

The method involves keeping a bit in an Internet protocol header of a high priority packet, indicating a preemption indicator at 1 if a packet/a fragment of packet of low priority is in course of transmission. The high priority packet is transmitted with the indicator between a transmitter and a receiver. The transmission of the low priority packet/fragment is resumed to the end of transmission of the high priority packet. An independent claim is also included for a system for transmitting packets of high priority in an Internet protocol (IP) transmission network.
