推导了在波松误码模型和突发误码模型下 ,比特块产生差错的概率、检测出差错块的概率和检测效率的数学表达式 .在此基础上 ,模拟并分析了不同 EDC所能检测的最大误码率 (饱和误码率 )和最低检测效率 ,得出为每个串接监视域分配一个 BIP字节可以满足性能监视的需求的结论 .如果要求 EDC的检测效率至少不低于 90 % ,可以采用 2× BIP- 4差错检测方案 ;如果不需要实时地测量性能状态 ,可以采用 8× BIP- 1差错检测方案
The mathematical expressions of the probability of error generation, the probability of error block detection and the detection efficiency of the bit block under the Waveson error model and the burst error model are deduced.On the basis of this, The maximum error rate (saturation bit error rate) and the minimum detection efficiency, concludes that one BIP byte is allocated for each CS domain to meet the performance monitoring requirements.If EDC detection efficiency is required to be at least not less than 90 %, A 2 × BIP-4 error detection scheme can be used; if no real-time measurement of the performance state is required, an 8 × BIP-1 error detection scheme
