5 O3 Project Concept, Approach & Goal Open, Organic, Optima Anyone, Anything, Anywhere Neutrality & Efficiency for Resource, Performance, Reliability,. Multi-Layer, Multi-Provider, Multi-Service User-oriented SDN for WAN Softwarization: Unified Tools and Libraries On-demand, Dynamic, Scalable, High-performance Features Object-defined Network Framework SDN WAN Open Source Software SDN Design & Operations Guideline Accelerates Service Innovation, Re-engineering, Business Eco-System 5

6 O3 Deliverables: User-oriented SDN Provides Orchestration for different user requirements I'd like to change AP performance dynamically. Management for AP providers (ex. Skype, Lync, Facebook) Management for service providers (ex. IaaS, PaaS, SaaS) I'd like to automate service management including IT systems. Management for carrier network (ex. Design, Deploy, Operate) Northbound API (Innovation for users) Open Network Platform Southbound API (Innovation among vendors) Packet Optical Mobile Physical network I'd like to control and operate n/w in finegrained manner. Flexible n/w platform for various requests from users. 6

7 O3 Object-defined Network Platform Network is abstracted as graph of base objects Control functions are the operators for the objects Different types of NW are defined through extension of objects AP provider Service provider Carrier Extended operator function (for AP provider) Extended operator function (for Service provider) Specify only the bandwidth, delay, SLA on the abstraction layer. Open Network Platform (ODENOS) Object Object Object Object OpenFlow Basic operator function Driver (Protocol-object convertor) Overlay Optical/packet transport Extended operator function (for Carrier) Mobile Find-grained control of routing, traffic, fault monitoring, and operation management.

29 OpenFlow OAM Tools Topology tool OAM functions for OpenFlow NW is necessary to operate SDN-WAN. To confirm availability of flows, NW topology management and relationship of FlowEntry and flow information is important. NTT Com developed and evaluated topology discovery tools that works under universal circumstances. Entry manage To manage flows, it is necessary to create FlowEntry form highly abstracted flow information such as location information, bandwidth and so on. We studied data model that describes necessary information manage SDN networks. Topology tool Entry manage 29
