The PTAnalyzer consist of three types of HW based high accuracy probes, a server handling supervision tasks, a configuration & reporting tool and 3 party probe license SW intended for integration in equipment such as CPEs and RBS. The system scales from a 2 probe minimal performance measurement tool, up to a full scale network mesh supervision system.
Measurement or supervision sessions are set up between probes as configurable simplex end-to-end traffic flows.
The system supervises performance statistics based on active measurements and filters for alarm and event-reporting.
An external system receives a trap at alarm and may solicit the Prosilient system for more detailed information.
Alternatively, the measurement results are downloaded from the probes to a central application for manual analysis and presentation.
The common practices of today defining network QoS performance can be summarized as:
-- Using SNMP polling to calculate a network average.
-- Using a specific technology as QoS argument.
-- Using over-provisioning combined with a maximum delay 'ping' as QoS statement.
Regardless of network technology or method, the following parameters perceived by the individual user or customer define the quality of an IP connection:
