Device and method for relay waving absorbing

Abstract

A delay fluctuation absorbing device includes transmission delay fluctuation absorbing buffers and CPUs. Each transmission delay fluctuation absorbing buffer stores packets sent through a network. Each CPU reads out each packet from the buffer a predetermined read delay time after the packet is stored in the buffer, and updates the read delay time of the buffer on the basis of the transmission delay time of the packet at unit time intervals. Each CPU shortens the read delay time step by step when the read delay time is to be shorted by updating. A delay fluctuation absorbing method is also disclosed.

Description

technical field [0001] The present invention relates to a delay fluctuation absorbing apparatus and method, and more particularly to a delay fluctuation absorbing apparatus and method used on the side of a receiving apparatus when voice communication is performed using Ethernet, ATM (Asynchronous Transfer Mode) or the like. Background technique [0002] Conventional equipment for transmitting / receiving packetized voice information has used techniques to maintain continuity in voice communications by using buffers on the receiver side after absorbing transmission delay fluctuations within an allowable time period error , start reading the received packets. [0003] However, the conventional technique causes the following problems. According to Japanese Patent Laid-Open No. 64-29141 (Document 1), the read timing of the transmission delay fluctuation absorbing buffer is fixed depending on the buffer used. Therefore, if the read timing is set earlier, the information of the vo...
