摘要
研究一种利用空闲帧进行误码统计来实现自动纠错的技术,这样可以根据线路误码情况自动开启或关闭纠错功能,充分利用带宽,同时空闲帧的引入还能够抵抗流量分析,增强了网络的安全性。首先提出了空闲帧和自动纠错的实现方案,然后根据方案设计板卡进行了验证,试验结果表明,该技术能够实现自动纠错,纠错后通信质量得到明显的提升。在业务数据的流量达不到配定带宽时,填充空闲帧,使线路流量始终维持在配定带宽上,即能够抗流量分析。
Auto error-correction could be implemented by error statistics with idle frame,thus to realize automatic start or stop of error correction and full utilization of the bandwidth.Meanwhile with the introduction of idle frame,the traffic analysis could be resisted,and the network security enhanced.This paper puts forward first the implementation of idle frame and auto error correction,then validates it on testing PCB.The experiment results prove that this technology can realize auto error correction and resist traffic analysis,which makes the communication quality improved obviously.
