SBKIM TMN-2000 (ITU-T) Korea Telecom KNOM-Tutorial 2000
TMN Activities …. (ITU-T) SBKIM q Principles and Architectures - Reviced principles and architectures to support the multiple management technology paradigm environment (M. 3010) - TMN considerations, including focus on existing and emerging paradigms (M. 3013) q Methodology using UML to support a multiparadigm environment (M. 3020) q Protocols : CORBA and EDI for Inter-TMN interface (Q. 812, Q. 814) q Enhance Functional requirements and Information modelling ( M. 3400, Q. 82 x, Q. 83 x ) Korea Telecom 17 KNOM-Tutorial 2000
TMN dead or alive ? SBKIM q Words, words…. - ”The telecom industry has long held up the Telecommunications Management Network (TMN) as the ideal blueprint for operations management…. The question on everybody’s mind seems to be whether TMN works as well in practice as it does in theory. ‘ - “Last month’s Global TMN and OSS summit focused on issues and innovations shaping the future of next -generation networks…But things got ugly when various speakers and attendees at the conference were seen mouthing the words ”TMN is dead. ‘ q But, TMN really provides: — Logical Layered Architecture : ”TMN products should clearly identify the functionality they provide in terms of the five logical layers. ‘ — Management Functional Areas (”FCAPS‘) : ”TMN products should clearly identify the functionality they provide in terms of the five Management Functional Areas. . . [and] also provide common operations functions. . . ‘ — Information Models: ”TMN. . . describes an object- oriented approach for in formation exchanges in interactive management transactions…‘ — Open Standard Interfaces : ”Open standard interfaces should be used whenever possible. . . ” q TMN is still alive and …. . - Most aspects of TMN have been very widely accepted and have been extremely influential in the OSS marketpla ce - Major exception TMN has been traditionally associated with the CMIP protocol, which has not been widely accepted Korea Telecom 18 KNOM-Tutorial 2000
TMN for Next Generation(TMN 2000) SBKIM n Current generation of TMN infrastrucure => single manager and agent system => single communication protocol => static domain Next generation of TMN infrastructure => distributed management: diffused functionality => inter-domain management : OSI, DPE, Internet => interoperability and portability evolution Korea Telecom 19 KNOM-Tutorial 2000
TMN 2000 for Next Generation SBKIM q Two track approach including existing and new emerging paradigm environment q Management paradigm: CORBA for intra. TMN use and other emerging paradigm(eg. XML) q Integrated management of mixed circuit and packet/IP networks: support of SNMP q. TMN management support for IMT 2000 Korea Telecom 20 KNOM-Tutorial 2000

Hurdles to Overcome SBKIM q No “generally accepted” architecture that we can all base our systems on. q We spend too much time “getting systems to connect” and not enough time on “getting the functionality we need”! q We cannot change the systems as fast as the business is changing. … 50% of the work of integrating two systems in in the “plumbing” and “adapters”. This wasted work that takes away from creating actual usable functionality. q We cannot buy/ build/ lease new systems functionality without affecting everything currently installed. Korea Telecom 43 KNOM-Tutorial 2000
NGOSS (New Generation Operation System and Software) SBKIM Goal q Secure a leadership position by successfully delivering NGOSS with significant industry support. Program Objectives q Establish the NGOSS reference architecture as the industry’s umbrella architecture for all OSS solutions (Q 1 2001) q Deliver NGOSS reference implementation (Q 2 2001) q Gain involvement from key groups by launching collaborative work on key elements q Create market momentum by attracting support of pacesetter companies q Extend acceptance into other key sectors (ASPs, ISPs, etc. ) Korea Telecom 44 KNOM-Tutorial 2000
