AAL2分组话音复接器的研究与实现

STUDY AND IMPLEMENTATION OF AAL2 PACKET VOICE MULTIPLEXER

该文研究在ATM虚通路带宽利用率一定的条件下,AAL2分组话音复接器性能随ATM虚通路输出速率的增加而变化的情况。得出结论:当ATM虚通路带宽利用率一定时,ATM虚通路输出速率越高,AAL2分组话音复接器的分组丢弃概率和平均分组排队时延越小。并提出了一种AAL2分组话音复接器的实现方案。该方案可以随着ATM虚通路输出速率的增加,方便地复接多个E1话音电路上的话音数据。

This paper investigates the performance of the AAL2 packet voice multiplexer as a function of the transmission capacity of the ATM VC when the ATM VC bandwidth utilization is constant. A conclusion is drawn that packet delay and probability of packet loss will decrease when the transmission capacity of the ATM VC increases. Finally, an implementation of AAL2 packet voice multiplexer is presented which can easily multiplex the voice calls from multiple El voice circuit.
