AIDA-NG is equipped
with tools that allow to manage software releases and administer global
system configuration data centrally; system parts are automatically updated
with all required data during start-up. This also goes with monitoring:
Even though there are different components that make up the system, these
can be monitored by any Operator Working Position, or by several simultaneously.
The Working Position displays the states of both the system as a whole
and its single major components so that all operators are continuously
informed on status changes. Further systems that are not necessarily at
the same location, such as additional contingency and test systems, can
also be monitored and controlled via the very same HMI.
This brings about the following advantages:
- Time-consuming and error-prone manual software installation and upgrade
tasks on single system components are no longer necessary.
- De-centralised architecture allows, for instance, to centrally manage
two systems located at different sites.
- The smooth switchover from one site to another makes contingency management
very save and simple; switching over the operational services is therefore
only a matter of minutes.
HMI Features
- AIDA-NG provides a fully graphical, clear-cut, and intuitive user
interface.
- All functions can be accessed concurrently from several Operator Working
Positions.
- Apart from hierarchically structured dialogues and menus, an object
browser allows fast and direct access to related objects such as system
parameters and diagnostic values.
System Parameter Handling
- Nearly all system parameters can be changed and activated online
without the need to restart the system.
- The hardware-related configuration is part of the system parameters;
modification of these parameters, such as activation of new interfaces
or changing physical interface characteristics (e.g. V.24 to V.11),
influence the system performance and availability in no way.
- Parameter input is menu-driven and facilitated by selection lists.
- Inputs are immediately checked on validity as well as cross-checked
against related parameters, so that the user is prevented from entering
inconsistent data.
System Inspection
Throughout all system levels, the system permanently
collects diagnostic and statistic values of all available resources:
- system component states and resources,
- message routing,
- remote connection states and protocol-stack-related values (data line
monitoring),
- operating system and hardware status,
Based on diagnostic values, the system generates absolute,
average, and peak statistics in different resolutions (minute, hour, day,
month, year). All values can be displayed, printed, and exported to spreadsheet
applications such as Microsoft® Office Excel. The connection states
to communication partners can be visualised in logical and geographical
maps.
Event and Alarm Handling
- All changes in the system are reported and stored as events.
- The visual and acoustic presentation of events can be configured individually
with the help of the corresponding alarm attributes.
