SYSTEM FOR CONTROLLING PATH MAXIMUM TRANSIMISSION UNIT BY DETECTING REPETITIONAL IP PACKET FRAGMENTATION AND METHOD THEREOF

摘要

PURPOSE: A route maximum transfer unit control system according to the duplication division packet detection and a method thereof are provided to detect the multicast environment, the duplication IP packet segmentation and reduce the loss of the packet. CONSTITUTION: A packet capture unit(411) captures a received packet to a quality measuring apparatus. A duplicatedly division detector(412) detects the packet in which the captured packet. The detected packet transmits maximum transmission information to PMTU(Path Maximum Transmission Unit) information transmission unit(414). The route maximum transfer unit information obtains with the duplication division detection unit.
