RADview-HPOV, a UNIX-based element management system, is designed in accordance with ITU-T TMN recommendations for SNMP and implements fault, configuration, accounting, performance and security management. RADview-HPOV includes extensive network level functions, for example, software download, statistics collection for (ATM/TDM networks), automatic, TFTP-based device configuration download and storage, as well as network level date/time synchronization. RADview-HPOV is based on HP's OpenView Network Node Manager (NNM) and can coexist with third-party element management systems.

 

Configuration Management - RADview-HPOV features user-friendly and intuitive zoom applications, a simple yet powerful configuration tool, simplifying device configuration tasks. A configuration planner is available for selected TDM devices, allowing off- line network planning and simulation. Backup and restore of network elements, network connection or complete topologies allow storing and restoring configuration information.

 

TFTP-based software and configuration transfer capabilities allow distribution of new software versions or configuration files to multiple network elements simultaneously, while collecting statistics and presenting reports on the process status. Configuration files can also be collected and distributed. TFTP sessions can be scheduled to automate periodic configuration upload tasks and simplify implementation of backup policies.

 

Fault Management - RADview-HPOV monitors the network, detects events, and helps isolate and minimize network downtime. Network status changes are displayed graphically at the network, device, card and port levels. RADview-HPOV supports multiple map levels enabling graphic display of the hierarchical network structure. A problem occurring at a lower level is forwarded to intermediate and upper levels for easy problem detection and isolation.

 

A comprehensive log file of all traps includes identification of the trap source, event description, and date/time stamp. Information in the log is categorized according to severity level, and can be sorted, filtered and exported to file for further analysis.

 

Performance Management - Network throughput and error rates are analyzed and controlled. Thresholds can be set for various variables, such as error rates, for immediate indication of network status. Real-time or last-24-hour network performance information can be displayed in table or chart format. In addition, performance information is collected per node/port (for TDM equipment) or per node/port/VP/VC (for ATM networks) per day. Collected data is stored in ASCII files for simple import by any external report generation utility.

 

Security Management - As a UNIX-based system, UNIX security enforces and restricts access to the RADview-HPOV console. In addition, RADview-HPOV login/password and security mechanisms define four types of users: 

- Administrator: full access to all network elements; additionally, can define users and associate privileges to them. 

- Operator: full access to configure a selected network element list.

- Technician: read-only access; additionally loop/test activation privilege.

- Monitor: read-only access.

 

Accounting Management - Performance data stored by RADview-HPOV, together with logged traps, provide long-term information on network status and can be used as a basis for external service level agreement (SLA) reporting tools.
