Elements and Performance Criteria
- Evaluate network capacity and traffic problems
- Interrogate network alarms to identify areas of route and circuit unavailability
- Assess planned and unplanned outages to determine network unavailability and verify restoration times
- Interrogate system to identify traffic status using network management system
- Analyse system alert to identify real and potential traffic problems
- Analyse customer complaints and traffic measurement data to identify network problems
- Activate and deactivate semi-permanent controls active in the network on a regular basis to simulate irregular traffic
- Develop strategies to overcome network traffic problems
- Conduct traffic measurements across all identified routes
- Analyse results including historical data to make assessment of traffic volume requirements
- Determine specific thresholds, loading and grading levels to alter traffic flows
- Liaise with personnel to determine amendments to plan, based on funding parameters and budgeted levels
- Develop strategies, based on traffic analysis and patterns, to control traffic and prevent congestion or other traffic problems
- Develop strategies for recovery where traffic congestion occurs
- Develop contingency plans to allow for problems during network changes
- Apply short and long term solutions
- Implement software changes according to planned strategy
- Develop short-term ad hoc solutions where only a temporary solution is required
- Ensure reversal action can be initiated in cases of temporary solutions
- Implement contingency plan where required
- Undertake monitoring of changes and take measurements to assess outcomes of variations
- Prepare a report based on analysis of measurements for appropriate personnel with recommendations for further changes or actions
- Review and monitor strategies regularly and initiate corrective action where required
- Detect and take action on potential traffic congestion
- Provide traffic indicators for capacity planning
