METHOD OF OPTIMIZING TRAFIC IN DIGITAL PACKET SWITCHING METWORK

摘要

PURPOSE: To improve traffic between real time terminals to be executed through a switching network by including a field indicating whether or not packet is suited to be clipped in the switching network in the packet. CONSTITUTION: A bit H1 bit PC(clipping prevention) included in a packet indicates that a packet previous to this communication is abandoned in one of nodes. The function of a first clipping mechanism can be improved by inspecting this PC bit before the packet is abandoned, and a transmission priority is applied to the packet in which the PC bits are turned on for escaping the continuous clipping at the time of abandoning the packet suitable to the clipping. Thus, continuous voice packet disappearance can be reduced in a digital network.
