Pertemuan 12 TMN

1. Matakuliah : H0372/Manajemen Jaringan Tahun : 2005 Versi : 1/0 Pertemuan 12TMN

2. Learning Outcomes Pada akhir pertemuan ini, diharapkan mahasiswa akan mampu : • Menunjukkan TMN sebagai manajemen jaringan khusus

3. Outline Materi • Model TMN • Operations Systems

4. TMN • Necessity for interoperability basis for TMN • Need for management of more than just the network components • Networks / subnetworks need to be managed • Services - internal and external need management • Business management needs to be addressed • TMN joint effort by ITU-T and ISO

5. Workstation Operations Telecommunications Management Network Operations Operations System System System NMS Data Communication Network Switching System Switching System Switching System Transmission Transmission System System Voice Voice Telecommunication Network TMN Conceptual Model

6. TMN Functions • Configuration Management • Network Planning and Engineering • Installation • Service Planning and Negotiations • Provisioning • Status and Control • Fault Management • Quality Assurance • Alarm Surveillance • Fault Localization • Fault Correction • Testing • Trouble Administration

7. TMN Functions • Performance Management • Performance Quality Assurance • Performance Monitoring • Performance Management Control • Performance Analysis • Account Management • Tariffing/Pricing • Usage Measurement • Collection and Finance • Security Management • Protection • Detection • Containment and Recovery • Security Administration

8. Element - Network - Service • Element Management - components, elements • Centralized or dedicated, few NE types, element view • Network Management - network connections • Centralization, multiple NE types, network view • Service Management - billable services • Centralized, NE type independent, customer view

9. TMN Architecture TMN Architecture Functional Physical Informational Architecture Architecture Architecture • Functional architecture: • Functional modules or blocks • Reference points between modules • Physical architecture: • Physical blocks • Physical interfaces between the blocks • Informational architecture: • Information exchange between entities • Object oriented

10. TMN Reference Point Function Block Function Block Reference Point • Function blocks connected by conceptual interfaces, called reference point • Designated by lower case letters (upper case letter for physical interfaces) • x: Interface between operations systems that belong to different domains; e.g., interface between two NMSs belonging to two different domains • q3: Interface between two OSFs in the same domain • qx: Interface between mediation function such as RMON and agent in the network element • f: Interface to the workstation

13. Functional Architecture • OSF: • Functions performed by Operations systems: e.g., NMS, testing, accounting, trouble tracking • NEF: • Functions needed to support network elements;network elements themselves are not part of TMN: e.g., NM agent, MIB, collision rate • MF: • Operations on the information between network elements; e.g. filtering, protocol conversion. MF can be shared between multiple OSSs; e.g. RMON • WSF: • Human-TMN activities interface; e.g., GUI • QAF: • Adapter function to accommodate non-TMN entities; e.g. proxy server, SNMP-to-CMIP
