1 Service Orientation in Software Defined Networking HCL Technologies Shashidhar Krishnamurthy, Anurag Jain and Saurabh Chattopadhyay Future Network Technologies Workshop 9 11 Apr 2013 ETSI, Sophia Antipolis, France 1 1

2 Why Service Orientation in SDN? Standardization Of Complete SDN Model needed at faster pace Data Centers / Provider of Internet based Services Storage 1 Storage 2 (Vendor 1) Storage 3 (Vendor 3) Storage 4 (Vendor 5) Service 1 Service 2 Service 3 Customer Pays for Service Service 4 Service 5 Service 6 System 1 System 2 System 3 System 4 Network Service Provider Last Mile Device 1 Last Mile Device 1 (Vendor 1) Last Mile Device 3 Last Mile Device 2 (Vendor 3) Connectivity Service Bundle 3 (Technology Mix) Connectivity Service Bundle 1 (Technology 1) Connectivity Service Bundle 2 (Technology 2) Profitability of service needs automation and user control System 1 System 2 System 3 System 4 Backbone Provider / Upstream Operator Equipment Provider / OEM Services Provider Backbone Service Bundle 1 (Technology 1) Backbone Service Bundle 1 (Technology 2) N/w Device 1 N/w Device 1 (Vendor 1) N/w Device 4 N/w Device 2 Backbone Service Bundle 3 (Technology Mix) Upstream Service Bundle 1 (Technology 1) N/w Device 10 as a Service (Vendor 3) System 1 System 2 N/w Device 5 as a Service (Vendor 4) N/w Device 3 (Vendor 3) Upstream Service Bundle 2 (Technology 2) Policy management needs tight integration with service design functions A Service Oriented SDN model shall address business challenges of highly N/w Device 2 N/w Device 3 (Vendor 1) (Vendor 1) dynamic and virtualized applications Upstream Service Bundle 3 (Technology 3) N/w Device 7 (Vendor 5) N/w Device 8 (Vendor 6) N/w Device 9 (Vendor 7) System 3 System 4 2 2

3 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

4 Business Driver - Services & Optimization using SDN Open Networking Summit, April 2012 Potentials to improve bottom line thru SDN Programmability & Automation Challenges 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 4 4 Shipping SDN Products Category No. of Vendors No. of Devices HW Switch and Routers CONTROLLER 4 4 VSWITCH 5 5 Announced SDN Products Category No. of Vendors No. of Devices HW Switch and Routers 4 6 CONTROLLER 3 3 VSWITCH 1 1 Market Investment in N/w Infrastructure Current State of Adoption for SDN

5 SDN s Required Positioning in Service Orientation Landscape Service Orchestration Environment Service Enablement Service Management Network Orchestration OnePK Junos / JSpace SDK Others Encapsulation over Proprietary / Vendor Specific APIs & SDKs Compute Resource Orchestration Standard / Industry Bodies Initiatives Programmability Enablement Service Lifecycle Mgmt NFV / ETSI ISG Initiatives OpenFlow & ONF Initiatives Vendor specific Initiatives (MSFT Azure, VMWare, ) API / SDK Lifecycle Mgmt Service Composition Environment Service Inter-Op Enablement Customer Relationship Mgmt SDK / API Entry-point (Operator specific SDK Access Gateways like AT&T, Verizon, etc.) Device Environment (Android, ios, Blackberry, Windows Mobile, ) Service Creation Environment Hosted Environment (Operator Hosted Environment like IMS etc, OTT Hosted Cloud like Amazon, Google, Microsoft ) Enabling APIs Identity Location Payment Other Partner Alliance Mgmt Networking & Computing Resource Mgmt Standard / Industry Body Defined Vendor Specific / Productized Hybrid / Innovation Focused 5 5

6 Key Requirements for SDN aligned Network Orchestration Cisco OnePK Junos & JSpace SDKs Other Vendor specific SDN Central Orchestration Plane Structural Abstraction over Fixed Network Architecture Behavioral Abstraction over Network Dynamics Meta- Information Model API Accessibility & Management Platform Central Gateway Function for API Accessibility and API Manageability Function Structural Abstractions to gain control over defined roles and responsibilities of key network functions from central orchestration plane Behavioural Abstraction over dynamic capabilities will help monitoring real-time change in environment and help refine Service Orchestration capabilities real-time Meta-Information Model to define information exchange schema while establishing control plane capabilities, potential to reuse relevant protocol data model definitions HetNet 6 6

7 Key Requirements for SDN aligned Programmability Enablement Programmability Enablement Options Legacy Networking Legacy Legacy Networking Networking Gear Gear Gear Guided & Fast Track Development of Embedded Programming Mediation to interoperate with Controllers / Applications, making device s control plane nearly redundant Guided Development to prepare External Mediation as Inter-Op Gateway ing Programmability and making Device s Control plane as nearly Redundant Programmable Programmable Legacy Programmable Legacy Networking Networking Networking Gear Gear Gear Migrating the Product to provide native support for SDN ing Programmability & Control Plane Abstraction Informative Recommendations on Migration Methods will accelerate SDN Enablement Standard Development Organizations may outline migration scope for products of various Network Functions 7 7
