Functional composition of the IP Qiality Monitor system could be seen here.

There are two main elements: IQMA (Agents) and IQMM (Managers).

Agents: There are special network appliances used for quality measuremets, which are located in the main network nodes. They are small computers running IQMA software, and are called probes or agents. Agents automatically (on demand or on schedule) run tests between them (agents) and measure delivery parameters losses, delay (RTT), variation (jitter) and bandwidth. Gathered data is than pre-processed, stored in text files and delivered to higher level –

Manager. IQM Manager is the brain of IQM system, providing agent management, data processing and analysis, user interface. IQMM provides:

• IQMA agents management:
• Policy configuration
• Threshold management
• Test by schedule configuration
• Test by demand configuration
• IQMM (lower level managers) management for distributed systems
• Automated processing of acquired data:
•  Export of data to SQL DB
• Data reduction and pre-processing for storage
• Data storage
• Data analysis and consistency checks
• Data violation signalization
• Stats graphing and user interface
