Objectives of P708Objectives of P708Xcoop validated specification for:• Performance Management• Accounting Management

Europe-wide infrastructurePET-Lab to test TMN X-

Interfacespecifications (any technology)Implement and Test (EURESCOM P710)

Security Solutions for the X-Interface


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


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
