  1. TMN X-Interface Studies and Experiments for ATM EURESCOM Project P708 Colin Smith (BT) Donald Ranasinghe (BT) Marina Geymonat (CSELT) Project Participants: Belgacom, BT, CSELT, Deutsche Telekom, Finnet Group, France Telecom, OTE, Sonera, SwissCom, Telefonica I+D

  2. Rationale Need for a global ATM VP service both in Europe and World-wide

  3. Inter-Domain Connections PNO D PNO A MANAGEMENT LAYER MANAGEMENT NETWORK PNO C PNO B ATM Network ATM Network NETWORK LAYER (ATM) ATM Network ATM Network

  4. Need For Issues at the Management Layer PNO D PNO A MANAGEMENT NETWORK PNO C PNO B • Co-operative Management of Interdomain Connections • Communications between Management Systems A Common Protocol A Standardised Interface

  5. Management System (Network Level) Management System (Network Level) TMN X-Interfaces: Xcoop, Xuser M3 Xcoop/M5 Xuser Customer Management System Q3 nw Q3 nw Management System (NE) Management System (NE) Q3 el Q3 el PRIVATE PNO A PNO B

  6. FAULT (ETSI-300 820.2) CONFIGURATION (ETSI-300 820.1) EXISTING Xcoop Functional Areas Specified in GDMO language Implemented with CMIP protocol PROTOCOL

  7. X.25 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

  8. REQUIREMENTS ISSUES 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

  9. 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

  10. 2 Separate implementation 1 Specification phase Xcoop Specification 3 Test Specification 4 Test Execution over the PET-Lab implementation updating Validation Methodology Test Execution revision of specification Passed? NO YES Validated X-Interface Specification

  11. Pan-European TMN Laboratory Interconnection of 6 Labs with multi-vendor Management Platforms Interoperating Each lab has an OSI stack Platform & Toolkit Testing of other networks TCP/IP (RFC 1006) ISDN Management Platform X.25 OSI stack

  12. 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

  13. Conclusions • X-interfaces are necessary for a global services • Only Validated Specifications should be • issued • The Pan-European TMN Lab is used for X- Interface specification validation • Performance and Accounting are still very • immature, but clear requirements for the • X-Interface have been identified • Security needed for commercial services
