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

Survey on innovation Imperative, September 2012 by CA Technologies

Large Fraction of USD 530 Billion Innovation Market can potentially get driven by SDN Challenges Business alignment is still evolving Less of Production grade state in current implementation 3 3

Key Requirements for SDN aligned Network Orchestration Cisco OnePK

Junos & JSpace SDKs

Other Vendor specific SDN … Central Orchestration Plane

API Accessibility & Management Platform

Structural Abstraction over Fixed Network Architecture MetaInformation Model

Behavioral Abstraction over Network Dynamics

Structural Abstractions to gain control over defined roles and responsibilities of key network functions from central orchestration plane

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
