Vorrichtung zur Absorption von Schwankungen in der Paketübertragungsrate in einem Kommunikationsnetzwerk

摘要

A fluctuation absorbing buffer apparatus configured to absorb, by means of a reproduction buffer, a transmission delay time fluctuation occurring in a voice packet communication system, includes: a packet state notifying part carrying out decrease notification when the number of voice packets stored in the reproduction buffer decrease; a voice determining part carrying out determination as to whether or not voice exists on the voice packets stored in the reproduction buffer; and voice reproduction control part repeatedly reproducing voice packets determined as not having voice when decrease is notified by said packet state notifying part.
