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

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

3. 3 Outline Materi Model TMN Operations Systems

4. 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. 5 TMN Conceptual Model Telecommunication Network Voice Data Communication Network Operations System NMS Operations System Operations System Workstation Telecommunications Management Network Transmission System Switching System Transmission System Switching System Switching System

6. 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. 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. 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. 9 TMN Architecture Physical Architecture Informational Architecture Functional 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. 10 TMN Reference Point 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. 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
