摘要
当分组传送网以时分复用方式承载电力通信实时业务时,去抖动缓存的参数选择成为提高业务性能的关键手段。文章首先分析了去抖动缓存参数对时分复用业务性能的影响机理,然后设计了缓存参数对业务性能指标影响的数值仿真算法,最后通过仿真实现了去抖动缓存参数的优化。结果表明,优化缓存区长度及分组封装尺寸能有效降低误码率,减少传输时延。
When the Packet Transport Network （PTN） carries the power communication real time service in the way of Time Division Multiplexing （TDM）, the parameter selection of de-jitter buffer becomes the key method to improve the service per- formance. In this paper, we first analyze the influence mechanism of de-jitter buffer parameters on TDM service performance. Then we design the numerical simulation algorithm to find the impact of buffer parameters on service performance. Finally, the optimization of de-jitter buffer parameters is realized by simulation. The results show that the optimized buffer length and packet size can effectively reduce the bit error rate and the transmission delay.
