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

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?

Slide 9

Terry Turner, TIInter-Operator TMN & OSS Workshop

Prague, 23-24 March 1999

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

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

Slide 12

Terry Turner, TIInter-Operator TMN & OSS Workshop

Prague, 23-24 March 1999

Drivers of TMN Evolution

• Separation of network control into middleware

• blurring control vs management distinction

• open control, active networks, TINA, ….

Slide 13

Terry Turner, TIInter-Operator TMN & OSS Workshop

Prague, 23-24 March 1999

Drivers of TMN Evolution

• adopt SNMPv3

• improve SNMP

• work with IETF to adopt CMIS

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 ?

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

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)

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!
