4. Conclusion
With the evolution of networks towards value-added services and the growing complexity of the protocols used, network metrology has become an indispensable tool for network verification and planning. The term metrology covers all the measurement techniques available in networks (we have limited ourselves to measurements made at the level of IP networks). The range of possible measurements is vast, and it is particularly important to know what you want to measure or highlight, in order to choose the right technique and parameters.
Measurements can be local or end-to-end, at different protocol levels (from application to physical), using active or passive probe tools...
Metrology gives access to more complex tools, such as traffic matrices or traffic classification, which have repercussions on the implementation...
