Similar to IOAM DEX, PBT-M does not carry the telemetry data in user packets but sends the telemetry data through a dedicated packet. However, PBT-M does not require an extra instruction header but claims a bit in existing header fields or uses some other equivalent means as a trigger for telemetry data processing and collection. Due to this feature, PBT-M raises some unique issues that need to be considered for its application in different networks. This document describes the high level scheme, summarizes the common requirements and issues, and provides recommendations for solutions. PBT-M is complementary to the other on-path telemetry schemes.}, }
