The measurement architecture to be implemented depends on the metrics to be observed. It can be local or end-to-end, as well as unidirectional or bidirectional.

Example

Measuring delays or losses requires an end-to-end architecture (unidirectional or bidirectional), while measuring the number of packet reordering operations carried out by TCP can be done with a local measurement architecture.

These architectures are presented in the following paragraphs. We will first distinguish between measurements made in the control plane and in the data plane, and then consider local measurements and end-to-end measurements.
