Outline
Piano di monitoraggio delle reti IP
Costituita da probe attive (user) e passive (in rete)
Analizza prestazioni e problemi
Ogni sonda rileva i suoi parametri e collabora, attraverso un
reasoner, con altre sonde
8 differenti Uses cases considerati
2
•A probe is a component that performs measurements.
•A repository is a component that provides access to a data source.
•A client is anything which uses the mPlane protocol to consume services provided by
one or more components.
•A supervisor collects capabilities from a set of components, and provides capabilities
based on these to its clients.
•A reasoner is a client which supports iterative measurement by learning the best
subsequent measurements to perform in order to drill down to the root cause of a
specified problem.
