摘要
在SDH通信系统中,通常都是使用缓冲存储器,保障时钟的同步及其数据流的平衡问题。为了使缓存正常工作,避免上溢或下溢现象,必须选择合适的缓存深度。根据实际网元应用,提出了计算合适缓冲存储器深度的方法,以避免缓冲存储器的滑动损伤。
In the SDH communication system, the problem of clock synchronization and the problem of data flow balance are usually solved by using buffer memory. A proper depth of buffer must be set for keeping buffer working normally and preventing buffer from overflowing downward or upward. According to actual network element application, a method of calculating the proper buffer depth is put forward to avoid the sliding transmission impairment of buffer.
