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

Slide 4



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



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?

Slide 9



Drivers of TMN Evolution

• allow move to IT solutions

• multi-protocol solutions

• better handling of legacy ?

Slide 10




• operator-operator & customer-operator

• gateways - audited fairness, security

• network management as a service

Slide 11




• Service management more like commerce than network management

• drive to use common IT approaches• wary to include in TMN standards yet

Slide 12




• Separation of network control into middleware

• blurring control vs management distinction

• open control, active networks, TINA, ….

Slide 13




• adopt SNMPv3

• improve SNMP

• work with IETF to adopt CMIS

Slide 14




• inter-operability of components/applications

• Common API’s to support services

• Is it a telecoms specific issue ?

Slide 15



Bottom-Line of TMN Evolution

• TMN is not universal or all-encompassing

• state why and when should apply TMN

• identify areas TMN should cover

Slide 16



P812 Results

• D1 TMN Evolution• Annex A, B - Status - Needs and

Review of architecture and technology

• Annex C Issues - Uncertainties about TMN (35)

• Annex D Case- Studies/Recommendations

• Annex E Service Providers’ Needs for TM• Web site - www. eurescom.de/public/deliverables/wwwdeli.htm

Slide 17



P812 Case Studies

• use of CORBA for producing agent interfaces to element managers

• adequacy of SNMP v3 in TMN• impact of increased distribution of management

system• impact of web technology• impact of active networks• MSM architecture and methodology (P610)

Tutorial value !!!

Slide 18



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!
