In Situ Operations, Administration, and Maintenance (IOAM) Extension for Bit Error Rate Measurement

Networks may experience transmission bit errors due to various factors, such as poor fiber quality, thereby corrupting packets. Merely measuring the end-to-end bit error rate makes it difficult to locate the exact link wich poor quality. Therefore, a measurement method is needed to collect bit error rate information along the entire path to locate the specific linke with poor quality. This document extends IOAM with a new Trace-Type and "Interface Bit Error Rate" field to collect the interface error rate along the path. This new Trace-Type is applicable to Pre-allocated Trace, Incremental Trace, and Direct Exporting Option-Type.
