End-to-End Active Measurement Architecture in IP Networks (SATURNE)

Abstract

Performance measurement is an important issue in IP Networks for both ISPs and final users. Active measurement represents an efficient mean of evaluation and an alternative to the important infrastructure investment needed for passive measurement. Nowadays, the increasing complexity of routing mechanisms and the evolution of transport protocols leads to unawareness on the effective routes in the network; the symmetry of the paths followed by the packets can no longer be assumed. For this reason, the one-way metrics experience a remarkable development, introducing new requirements, like the synchronization of the points of measurement.
