High Integration Costs Drive Need for Standards
While about 4% of service provider revenues are spent on operation systems…
50%+ of operations costs devoted to integration [source: Keith Willets, TMW Dallas 2003]
OSS interface standards could drive down the high cost of integration
Need to re-focus TMW work on development of an “integration framework”

Standards and Standardization
StandardsAgreed reference definitions for information exchange or proceduresDocuments and codeSuccess requires technical expertise
StandardizationThe process of driving the adoption of standardsDegree of adoptionSuccess depends on commercial and political viabilityEnabled by business owners and budget holders
This industry needs both!

Origins and Objectives of MTOSI
> Multi-Technology Operations Systems Interface
> Started as MTNM subteam mid 2003
> Objective: Extend MTNM model for OS-OS interfaces
> Based on MTNM 513 (BA), 608 (IM) and 814 (IDL)
> XML / Web Services integration interface
> Uses NGOSS and SOA design principles

MTOSI 1.0 Feature Highlights
Support for SOA / ESB principles: loosely coupled, coarse grain, reliable messaging
JMS binding and implementation guidelines
Supports backwards and forwards compatibility, major/minor versions
Module level versioningSupports web service standardsXSD, SOAP, WDSL definitions
Group operations by business process. Reduces compliance complexity requirements
Operations profilingTurns off notifications if desiredSource notification suppression
Scope and Filter replaces many fine grain operations
Inventory and fault notifications with scope/filter
Simplify requesting OS code, communicationsBulk inventory and alarm operationsBackwards compatible with 814-like interfacesFine grain operations
Flexible to support different interaction needsMultiple communication styles: sync, async, file transfer
Leverage existing deployments and expertise608 model with MD and OS extensions

MTOSI Status and Roadmap
> V1.0 and submitted for MTNM review ~Nov/Dec 04> TMF member ratification ~1Q 05> MTOSI to split from MTNM into separate team for V2.0> Intermediate versions 1.X to address miscellaneous technical enhancements (e.g., versioning, transport, state, filtering, etc.)> Version 2 may address new OS-OS interfaces such as:
Service ActivationService ProvisioningService Performance Management
> Will require extension of 608 model and unification with SID> Input and suggestions welcome. Please contact team lead Steve Fratini, [email protected]

Status & Next Steps
Functional spec of the two adapters complete
JMS adapter stubs tested & working
Adapter development under way2 x 2 development teamTarget availability mid-2005
Possible second trial with BT
Standard will be made available for other vendors to develop to
Encourage others to adopt the same approach (and interface)Vendors and service providers

Findings
MTOSI works!
MTOSI allows faster, simpler integration of NMS-to-OSS
MTOSI enables vendors to more easily integrate to a wider range of equipment (or OSS)
RAD-type development: standard + development + refinement
‘Two-part’ adapter approach decouples vendor productsHigh-value transactional interfaces
The ‘top-down’ approachSimplifies the interfaceEnables re-use – everyone can build to same interface

What does that mean for me?Good news for TMF
Practical experience as inputA complete and proven standard
Good news for vendorsA standardized northbound interface for equipment vendorsA standardized dataload/synchronization interface for inventory vendors
But most of all….
….Good news for Service ProvidersImproved vendor inter-workingLoosely coupled applicationsReduced integration costsReduced deployment timescalesReduced deployment riskReduced cost of ownership
