UNIX-based Element Management System

RAD's RADview-HPOV is a UNIX-based, user-friendly and powerful SNMP-based element management system, 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.

• User friendly and zoom applications

• Modular system architecture enables management of heterogeneous networks

• Friendly and realistic graphical user interface

RADview-HPOV features user-friendly and intuitive zoom applications, and is a powerful configuration tool, that facilitates device configuration tasks. A configuration planner is available for selected TDM devices, allowing off-line network planning and simulation.

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.

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 filtered and exported to file for further analysis.

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 export to any external report generation utility.

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

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

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

• Technician: read-only access; 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.

Note: Some RAD devices are managed via a Web-based element manager.
