As networks increase in scale, they become more susceptible to measurement accuracy and misconfiguration errors. With the advent of programmable data-plane, emerging on-path telemetry techniques provide unprecedented flow insight and fast notification of network issues (e.g., jitter, increased latency, packet loss, significant bit error variations, and unequal load- balancing). This document outlines an In-situ Flow Information Telemetry (iFIT) reference framework, which enumerates several high level components and describes how these components can be assembled to achieve a complete and closed-loop working solution for on-path telemetry. iFIT addresses several deployment challenges for on-path telemetry techniques, especially in carrier networks. As an open framework, it does not detail the implementation of the components as well as the interface between the components.}, }
