What do we mean by “TMN”?
• Here, TMN = ITU’s M.3010 and relations
• Architecture - functionality and structure
• Standards - interfaces to network elements, ..
• Technology - CMIS/CMIP, GDMO, …...

TMN’s Status - Dittberner Report
• those compliant tended to be large vendors’ products for large operators

Prague, 23-24 March 1999
TMN’s Status - P812 interviews
• implementation skills are scarce
• technology is not IT mainstream
• toolkits slow to emerge and expensive
• standards too complex with too many options
• doesn’t help with legacy
• bad reputation amongst early users

Slide 5
Terry Turner, TIInter-Operator TMN & OSS Workshop
Prague, 23-24 March 1999
The need for TMN standards
• originally (1988)– separate OS supply from NE supply
• now include– support diversity of telecom marketplace– ensure supply of management software– reduce risks of large expenditures
• even greater need for interoperability now than before

TMN Issues
• An Issue is something that slows the progress of arriving at a complete TMN.
• Issues categorised as related to• Service Providers’ Needs• TMN Architectures and Standards• New and Emerging Technologies
• Addressing the Issues - Who, When?

Drivers of TMN Evolution
• allow move to IT solutions
• multi-protocol solutions
• better handling of legacy ?

Slide 10
Terry Turner, TIInter-Operator TMN & OSS Workshop
Prague, 23-24 March 1999
Drivers of TMN Evolution
• operator-operator & customer-operator
• gateways - audited fairness, security
• network management as a service
![Page 11: Terry Turner, TI Inter-Operator TMN & OSS Workshop Prague, 23-24 March 1999 Slide 1 The Challenge of Diversity Terry Turner, Broadcom/Telecom Eireann](https://reader030.vdocument.in/reader030/viewer/2022032612/56649eaa5503460f94baebe6/html5/thumbnails/11.jpg)
Slide 11
Terry Turner, TIInter-Operator TMN & OSS Workshop
Prague, 23-24 March 1999
Drivers of TMN Evolution
• Service management more like commerce than network management
• drive to use common IT approaches• wary to include in TMN standards yet
![Page 12: Terry Turner, TI Inter-Operator TMN & OSS Workshop Prague, 23-24 March 1999 Slide 1 The Challenge of Diversity Terry Turner, Broadcom/Telecom Eireann](https://reader030.vdocument.in/reader030/viewer/2022032612/56649eaa5503460f94baebe6/html5/thumbnails/12.jpg)
Slide 12
Terry Turner, TIInter-Operator TMN & OSS Workshop
Prague, 23-24 March 1999

• Separation of network control into middleware
• blurring control vs management distinction
• open control, active networks, TINA, ….

Slide 14
Terry Turner, TIInter-Operator TMN & OSS Workshop
Prague, 23-24 March 1999
Drivers of TMN Evolution
• inter-operability of components/applications
• Common API’s to support services
• Is it a telecoms specific issue ?
![Page 15: Terry Turner, TI Inter-Operator TMN & OSS Workshop Prague, 23-24 March 1999 Slide 1 The Challenge of Diversity Terry Turner, Broadcom/Telecom Eireann](https://reader030.vdocument.in/reader030/viewer/2022032612/56649eaa5503460f94baebe6/html5/thumbnails/15.jpg)
Slide 15
Terry Turner, TIInter-Operator TMN & OSS Workshop
Prague, 23-24 March 1999
Bottom-Line of TMN Evolution
• TMN is not universal or all-encompassing
• state why and when should apply TMN
• identify areas TMN should cover
![Page 16: Terry Turner, TI Inter-Operator TMN & OSS Workshop Prague, 23-24 March 1999 Slide 1 The Challenge of Diversity Terry Turner, Broadcom/Telecom Eireann](https://reader030.vdocument.in/reader030/viewer/2022032612/56649eaa5503460f94baebe6/html5/thumbnails/16.jpg)

Concluding Remarks
• evolve to survive
• today - large vendors and large operators where stability exists and investment is high
• Where is stability needed or possible tomorrow ?
• Industry specific needs form TMN’s niche
***A New Paradigm for a New Millennium?***Maybe!
