摘要
为了减少带宽求,语音和视频需要通过编解码(Codec)的方式进行传输,编解码的压缩和转换过程是由其数据流的编解码标准决定的。结合目前主流VoIP网络对决定其容量的编解码协议等要素进行分析,给出VoIP网络容量的通用计算公式。
In order to reduce network bandwidth requirements, audio and video are encoded before transmission and decoded during reception. This compression and conversion process is governed by various codec standards for both audio and video streams, which determine the capacity of VoIP network. Provides a formula to calculate capacity under different eodee standard, introduces the basic VolP mechanism.
