Customer Pays for Service

Profitability of service needs automation and user control

Policy management needs tight integration with service design functions

A ‘Service Oriented’ SDN model shall address business challenges of highly dynamic and virtualized applications

Standardization Of Complete SDN Model needed at faster pace

Business Driver – Innovation / Business Transformation using SDN

SDN to act innovation enabler for all these technologies, can bring a positive outlook towards quantum of potential investment flows

Large Fraction of USD 530 Billion Innovation Market can potentially get driven by SDN

Business alignment is still evolving

Less of Production grade state in current implementation

Challenges

Business Driver - Services & Support Optimization using SDN

Potentials to improve bottom line thru SDN Programmability & Automation

SDN Benefits maximized if adoption spans end to end in particular environment

Immature state of current adoption in Legacy Devices among top barrier (Highlighted in > 40% survey respondent)

Adoption roadmap to converge with investment protection strategy

API Accessibility & Management

Platform

Central Gateway Function for API Accessibility and API Manageability Function

Meta-Information Model to define information exchange schema while

establishing control plane capabilities, potential to reuse relevant protocol

data model definitions

Behavioural Abstraction over dynamic capabilities will help

monitoring real-time change in environment and help refine Service Orchestration capabilities real-time

Structural Abstractions to gain control over defined roles and responsibilities of key network

functions from central orchestration plane
