Objectives of P708
Xcoop validated specification for:
• Performance Management
• Accounting Management
Europe-wide infrastructure
PET-Lab to test TMN X-Interface
specifications (any technology)
Implement and Test (EURESCOM P710)
Security Solutions for the X-Interface

Performance 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
PNOs are not comfortable with other
PNOs reading their performance data
Standards at the Network Level for ATM are
still immature
TMN Workshop
Antwerp, 27 May1998
Accounting Management
• 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

X - Interface Security
• Key feature for a trustworthy Inter- domain
management
• Co-operation with EURESCOM project P710 to test
the security solutions they propose
• A security reference architecture will be defined
allowing the integration of standard APIs (GSS) with
off-the-shelf components and existing management
applications
• Liaison with platform vendors to get security features
into commercial TMN platforms
TMN Workshop
Antwerp, 27 May1998
Conclusions
• X-interfaces are necessary for a global services
• Only Validated Specifications should be
issued
• The Pan-European TMN Lab is used for XInterface specification validation
• Performance and Accounting are still very
immature, but clear requirements for the
X-Interface have been identified
• Security needed for commercial services
