TWACNManagement Information
System
System Objectives• Provide a flexible management information system • Employ a hierarchical structure. • Offer a range of tools and managed objects to enable the
TWACN equipment to be configured, monitored and controlled via accesses from each LA.
• Offer distinct planning, running and analysis phases.• Exchange MIS data with peer MIS systems.• Ensure that access to the MIS and associated data is not
possible by the TWACN subscribers.• Provide a facility for managers to be able to communicate
via e-mail.
MIS Functional Objectives• The functional areas that the management system supports
are:
– Configuration: Related to configuration of the management system, network deployment and subscriber permissions.
– Faults: Related to system supervision, maintenance and logistics.
– Performance: Related to traffic supervision and network efficiency.
– Accounting: Related to statistics about load on the system and third party communications costs.
– Security: Related to network security and information security including audit trail.

Network Management System
Modeling & Simulation Tools
• OPNET is a comprehensive modeling environment
• Employs a three tier hierarchical modeling approach:– Network (Physical Topology)– Node (Module Definition)– Process (Informatics)
Radio Modeler• Accomplishes model using
calculations collected from transmitters, environment, and receiver characteristics.
• Propagation loss algorithms based on Long-Rice models.
• Supports satellite, Line-of-Sight and Omni-directional radio path modeling.
Key Capabilities
• With MIS interface, OPNET can probe existing network for statistics, and produce “as is” models.
• Permits multi-layer modeling to be recorded simultaneously with built in dependencies
• Reports can be published either in text or graphical formats
• Accepts GIS terrain data information that is compliant with DTED formats.
