Pertemuan 12
TMN
1
Learning Outcomes
Pada akhir pertemuan ini, diharapkan mahasiswa
akan mampu :
• Menunjukkan TMN sebagai manajemen jaringan khusus
2
Outline Materi
• Model TMN
• Operations Systems
3
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

Informational
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

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

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
