Packet output-controlling device

摘要

A packet shaper (24) includes: a TCP packet queue (245) for storing TCP packets; a UDP packet queue (246) for storing UDP packets; a scheduler (247) for outputting a packet from one of the queues (245),(246) into a rate-setting control unit (244). Control based on a total queue length is performed to deterioration of image quality or tone quality in the audio/visual communications according to a connection-oriented protocol like TCP.
