3 NFV/SDN - ONF & NFV(ETSI) ONF: Service Providers NFV: Carriers for ETSI Name Drivers Industry Start ONF Google, Facebook,.. Service Providers Network Functions Virtualization Deutsch Telecom, British Telecom,.. Carriers

4 NFV/SDN - Collaboration ETSI + ONF = SDN4NFV ONF and ETSI announce strategic collaboration for SDN support of NFV Agility Abstraction Optimization Telco Edge Acceleration Commodity Hardware OpenFlow HW/SW Separation IT 산업간의협력을통한글로벌경쟁력보유 (Creating cross-industry links)

5 NFV/SDN - Data Center NFV SDN

6 NFV/SDN - Physical Topology ETSI 의 NFV Topology: Inter Data Center SDN 표준확장필요 : NFV 는 SDN 의 Use Case NFV 표준구체화필요 : SDN 은 NFV 의하부인프라

7 Data Plane Control Plane Application ONF 의 SDN - APIs Northbound API: Applications East-West API: Between Controllers Southbound API: Forwarding Hardware Application Application Application Network Controller Software Northbound API OpenIRIS Mul OpenDaylight East-West API FlowVisor Southbound API OpenFlow Forwarding Hardware Forwarding Hardware Forwarding Hardware Forwarding Hardware

8 ONF 의 SDN - Controller in Market For What? Where? When and How? NFV Northbound APIs Protocol Plug-ins Southbound Protocols Network Elements 8

9 ONF 의 SDN - Shift What are legacy protocols? SDN: Enabling a shift from protocols to applications Program Database Protocol

10 ONF 의 SDN - Core Network for 5G 2G : CS Core 3G : CS and PS Core 4G : All PS (Flat IP) 5G : SDN --- WWW Phone SMTP HTTP RTP --- TCP UDP --- IP 이더넷 PPP --- CSMA async sonet copper fiber radio ---

13 ONF 의 SDN - vnic & DirectPath I/O vnic for Cloud Services DirectPath I/O for NFV Some Features are mutually exclusive with Edge Accelerations of DirectPath Functions

14 ONF 의 SDN - SDN Based NFV Substrate Integrated programmable NFV : End-to-End based Scale out, Critical optimization, Almost Wire Speed Controller vswitch NIC ToR Fabric Switch Packet Processor Router Virtual Machines Storage VM TX Firewall / Security Rate Limiting Billing Routing Phys TX

15 ONF 의 SDN - Specifications Constraints : Incremental improvement on 1.X pipeline Board decided 1.3.X is a long term release 15

16 ONF 의 SDN - L4-L7 statistics For What? Where? When and How? NFV L4-L7 stats types and characteristics for ONF L4-L7 architecture Stateless L4 stats Network attacks OpenFlow switch Stateless L7 stats Application attacks OpenFlow switch or other L4-L7 service function (DPI) Statefull L7 stats and telemetries APT L4-L7 service function (DPI) Existing OF and Stateless extension to OF1.4 / 1.5 Stateless OpenFlow Extension with floating pointer OF? Statefull OF extension for Layer 4-7 Services OF Future 16

17 NFV - SDN may fit into NFV October 15-17, 2013 at the SDN and OpenFlow World Congress, Frankfurt-Germany. OSS / BSS A Virtual Network Function (VNF) utilises these virtualised resources, and may use various VMs (Virtual Compute) connected via some Virtual Networks.
