OSS: Evolution or Revolution?Dave Milham BT GROUP CTO Office OSS Architecture and InnovationTMF Fellow

Agenda

• Business drivers on Communications Providers• OSS – An innovation partner

– From Bottom Line to Top Line– Agility and Innovation

• Evolving the current OSS systems estate• Service oriented Architecture

– A near term Evolution Goal– Strategic revolution

• New paradigm for Managing and delivering NGN Services– Impact Convergence of Communications and Computing on OSS– Convergence of Management and Intelligence

• Summary

Business Drivers on SP

• Bottom Line – Reduce costs

– Capital expenses (CAPEX)

– Operating expenses (OPEX)

• Top Line– Bolster current revenue streams

– Create new revenue streams

Moving OSS from a bottom line cost of doing business

Innovation: Attacker’s advantage

When market and technologies change….

• Create opportunities for new players

• Threatens established players

At the heart of transformation is an INNOVATIONthat meets customer needs

OSS Evolution Drivers

• 21C NGN Converged Network– Less CAPEX

– Lower OPEX

– Greater agility

• Customer satisfaction– Improved processes

– Bolster current Business

– Gain credibility for new businesses

• New service and innovation

21C Converged Network

• Reducing complexity of our infrastructure

• Eliminating 100,000 network components and significant cost

• Establishing a single platform that is multi-service and future proof on IP

• Optimised for reliability and performance

• Closely aligned to PSTN transformation

• Phased roll-out begins this year

Three customer experiences

• Lead to cash– The time between the identification of a customer and

getting revenue in the door

• Trouble to resolve – The time between the identification of a problem and its

resolution

• Concept to market – The time it takes to get new technology and service

concepts from the drawing board to the customer

Service Oriented Architecture

SOA Addresses?

• Legacy systems evolution

• Complexity of integration

• Reusability

• Improves agility with which systems are evolved and developed

BUT

• Only as good as the environment in which it is developed

Horizontal activities

Horizontal – Vertical SOA Standards Map

W3C OASIS WS-I

Telecom Vertical

TMF NGOSSETSI

TISPAN WG8

TMF SPLC

Other Sectors:

Government…

Why SoA Matters

• A change of Architectural Paradigm– Facilitates Re-use

– Allows evolution of Functionality

• Leads to an integrated Telecom and IT architectural model

• Allows SP to manage complexity in current systems estate

• Only practical model for achieving OSS Agility

SOA - Management Paradigm shift (2)Traditional Static Architecture

System/Application Interface

Assumption that relationships are static and 1:1

Exposed functionsRelationship N:1 and dynamic

SOA

Example: Number Management

Number Management Service

Normal Operations:•Assign Number•Query Status•Release Number

Quarantine Operations•Policy 1 number type A x days•Policy 2 Number type B y Days

Porting Operations:•Mark Number for porting•Initiate Number porting •Notify number porting•Notify Number ported

Dependency on Network Time/DateOperations

Addresses versioning and evolution

So where does Management fit in?

Management Requirements

• Separate management of Physical from Logical– Manage server and transport infrastructure separately from logical

functions

– Logical function can be anywhere and packaged differently from vendor to vendor

– Current EMS models assume static deployment functionality

– Applications and logical IMS functions could be moved dynamically on computing infrastructure ( Virtualisation)

– Think carefully before building specialised EMS systems for IMS logical functions

Management Requirements

• Management of Services– Static design time model prevalent for current Network don’t work

– Need models that can be evolved at run time.

– Key is a set of meta-models for defining management of NGN services

– Implementation by Templates

• Service Assembly– Aka SCF

– Creates increased agility

– Template and data driven implementation models

– Need to re think the governance models for standards

Possible management revolutions?

• SOAP over SIP• Could this be the best way to build EM Functionality

into an IMS?• WS Distributed Management WS-DM

– Planned use is for Application Services i.e. the physical software Platform

• Should WS-DM be used to mange IMS Logical Functions but over SIP?

• Could this be the management bridge between IMS, App Services , Content and Application industries?

Convergence of IT , Network Management and Intellegence?
