1 Getting started with O3 Project Achievement ~ Innovating Network Business through SDN WAN Technologies~ May 13, 2015 Satoshi Kamiya O3 project (NEC, NTT, NTT Communications, Fujitsu, Hitachi) 1
2 Agenda Innovation through O3 User-oriented SDN O3 Technologies for SDN WAN SDN Use Cases in O3 Project Getting started with O3 Project Achievement 2
3 Innovation through O3 User-oriented SDN 3
4 Toward open User-oriented SDN 3 Contributions for User-oriented SDN (1) Open development with OSS (2) Standardization of architecture and interface (3) Commercialization of new technologies Open Innovation over Network Platform (1) Open (2) Standardization (3) Commercialization 4
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. Data Model Data Model Data Model Data Model 7
8 O3 Technologies for SDN WAN 8
9 SDN Design & Operations Guideline Established the SDN guideline for carrier networks The guideline is required to design, deploy and operate large-scale SDN in the following steps. Drafting guideline Testing & analyzing Completed Doc. Draft includes Criteria to select SDN equipment -Capacity -Capability -Reliability etc. Criteria for evaluation -Flexibility -Time to deploy SDN, etc. Evaluation techniques - Design parameters identification - Testing and reporting templates Evaluation techniques - Test bed setup - HW/SW SDN feature evaluation - Design parameters certification - Test results analysis Evaluation program Evaluation program DB Test bed Sapporo Evaluation program Final document - test results - analysis reports Fukuoka Tokyo 9

11 Signal Interwork between Optical & Packet Enables. a wide variety of service quality & rapid service tune-up 11
12 Virtual Wireless Networks Support multiple virtual networks over wireless networks while avoiding degradation of high priority traffic even when traffic demand and data rate of wireless link changes over time Mobile core network Wireless backhaul environment LTE emulation system 12
13 SDN Framework: ODENOS Network Abstraction Model: Hierarchical Node, Port, Link, Flow, and Packet Enables easy extension & customization Object-defined Network Platform 13
14 Abstract Network Operators in ODENOS Slicer, Federator, Aggregator and Link-Layerizer Federator Aggregator Slicer LinkLayerizer 14
15 NW Operator: Slicer Slicer: creates copies of the network object based on the given policy: Edge ports, TCP/UDP port number (i.e., application) Enables multi-tenancy, multiple applications L3 Routing LearningSwitch RepeaterHub Sliced Topology Slicer Slicing Policy OpenFlowDriver Physical Topology Physical OpenFlow network 15
16 NW Operator: Aggregator & Federator Aggregator: creates single big-switch abstraction Federator: connects multiple networks Use Case: multi-domain controller (with controller hierarchy) 16
17 NW Operator: Link-Layerizer Link-Layerizer: creates a network from the upper-layer nodes and lower-layer paths (flows) Use Case: unified control of multi-layer networks L3 routing OpenFlow Network Topology Aggregator Single node Link-Layerizer Edge nodes OpenFlowDriver MPLS-TP Driver Core node Full-mesh MPLS-TP paths OpenFlow switches 17
18 SDN Use Cases in O3 Project 18
19 Proof-of-Concept: Physical Configuration WAN experiments with multi-vendor equipment 19
20 PoC on Multi-Layer & Domain Control 20
21 PoC on Network Visualization 21
22 PoC on Packet & Optical Integrated Mgmt Control of transport network based on simple requirements from users such as transmission speed and response time Flexible multilayer resource utilization to meet user requirements 22
23 Getting started with O3 Project Achievement 23
24 Conclusion & Future Work We have released the following O3-project deliverbles on line. Doc OSS OSS SDN Design, Deployment & Operations Guideline* *Currently only the Japanese version is available.
