Performance ManagementPerformance Management Monitoring of ATM VPs (including
parts over Inter- PNO Links) Real-time monitoring of performance
parameters & inspection of History Logs Setting of thresholds & alarm reporting to
Initiating PNO when exceeded
REQUIREMENTS
REQUIREMENTS
ISSUES
ISSUES PNOs are not comfortable with other PNOs reading their performance data
Standards at the Network Level for ATM are still immature
TMN WorkshopAntwerp, 27 May1998
Accounting Accounting ManagementManagement• No billing or charging scheme is to be produced
• Provide the PNOs with the necessary information to be able to account for the resources actually used by the customer
• Need to identify parameters to quantify the actual use of resources involved in an international VP service
• Real-time charging to customer

ConclusionsConclusions• X-interfacesX-interfaces are necessary for a global services are necessary for a global services
• Only Only Validated SpecificationsValidated Specifications should be should be issuedissued
• The The Pan-European TMN LabPan-European TMN Lab is used for X- is used for X- Interface specification validationInterface specification validation
• Performance and AccountingPerformance and Accounting are still very are still very immature, but clear requirements for theimmature, but clear requirements for the X-Interface have been identifiedX-Interface have been identified
• SecuritySecurity needed for commercial services needed for commercial services
