1 SDN OVERVIEW THE BUSINESS VALUE OF SDN Nigel Oakley DIRECTOR, ADVANCED TECHNOLOGIES, SDN

2 JUNIPER S SDN STRATEGY: General Principles Separate Centralize Use the cloud Common Platform Standard Apply Broadly 4 Juniper Steps Centralize Management Extract Services Centralize Controller Optimize the Hardware 1 Licensing Model Full Use/Elastic JUNIPER SOFTWARE ADVANTAGE Transferable Software Lifetime Assurance

3 6 GENERAL SDN PRINCIPLES Principles of SDN Separate networking software in 4 planes Forwarding, Control, Services and Management Centralize Management, Services and Control planes Adopt Cloud for elastic scale and flexible deployment, enabling usage-based pricing Common Platform for network and security applications and management integration Standard protocols for interoperability across vendors Broadly Apply to Network & Security, Enterprise & Service Provider networks, Mobile & Wireline Customer benefits Optimize each network element Simplifies network design and lowers opex Reduce time to services and correlates cost based on value Enables new business solutions Provides choice and lowers cost through interoperability Flexibility and new business opportunities

4 SDN 4 LAYERS ORCHESTRATION MANAGEMENT Platform Applications API s EASIER Automated orchestration & provisioning to enable private/hybrid cloud CONTROL SDN CONTROLLER: NETWORK ORCHESTRATION Control Analytics Configuration FINANCE HR MARKETI NG FLEXIBLE Agility to enable multi-tenant networks SERVICES ADC, FW, IPS, Traffic Mon, DDoS, etc. FASTER Elastic scaling for rapid deployment of L4-L7 services FORWARDING Routing Security Switching LOW RISK Open, Programmable physical networks with future proof investment protection

5 1 ST STEP TO TRANSITION TO SDN CENTRALIZE MANAGEMENT Centralize Centralize management, analytics and configuration to provide a single pane of glass Optimize operations Integration with OSS/BSS and orchestration systems for centralized decision-making and execution through APIs

6 JUNOS SPACE FLEXIBLE MANAGEMENT PLATFORM FOR SDN Junos Space Centralized, Automated Network Management Junos Space SDK & APIs Programmable interface to customize apps/ Easy MoM & 3 rd party integration Junos Space Management Applications Junos Space Network Director, Security Director, Service Activation Director Junos Space Network Management Platform Deep EMS w/ extensive FCAPS, provisioning, extensive automation

7 2 ND STEP TO TRANSITION TO SDN EXTRACT SERVICES Extract Services (Network Function Virtualization) Extract services from network and security devices by creating service VMs Leverage cost and sourcing advantages of x86 servers Enable dynamic scalability and enhanced service agility Leverage existing investment in the Mx to offload services to the Mx, while running these services on x86

10 3 RD STEP TO TRANSITION TO SDN CENTRALIZE CONTROLLER Centralize Controller Centralize controller to have a broad view of the network and holistically optimize traffic flow Service chaining enables multiple network and security services to dynamically connect in series and be inserted into traffic flows Increase network agility and decrease provisioning time SDN controller is logically centralized but can be physically distributed

11 BARRIER TO PRIVATE/HYBRID CLOUD CAN I VIRTUALIZE MY Compute Storage Network X

12 NETWORK VIRTUALIZATION JOURNEY VLAN Manual configuration of VLANs at every switch Performance Management, Scale Tenant IDs Service insertion is complex Manual. Inefficient. Low scalability. Fragile.

13 NETWORK VIRTUALIZATION JOURNEY EARLY CIVILIZATION: OPENFLOW CONTROLLER Centralized Openflow Controller Touch every switch, as new tenants/vm are added First packet of every flow is punted to controller Openflow Forklift upgrade to Openflow supported hardware High latency. Low scalability. New failure mode. Fork-lift upgrade.

14 NETWORK VIRTUALIZATION JOURNEY PROACTIVE OVERLAY NETWORKS Packets are not punted to controller Controller proactively programs virtual overlay switches & gateways only Existing protocols establish IP fabric underlay No per-tenant state in physical network: Switches only know physical servers Low latency. High scalability. Robust. Evolutionary.

16 4 TH STEP TO TRANSITION TO SDN OPTIMIZE HARDWARE Optimize Hardware Optimize hardware based on a simplified set of functions it needs to perform due to the separation of the four planes SDN ready platforms that are Open and Programmable Flexibility to choose optimized hardware for high performance or generic hardware for low cost

17 THE FACTS Still early days New acronyms Physical networks NVGRE 15 % of Enterprises are very familiar with SDN STT MPLS QinQ VXLAN OTV OPENFLOW OVSDB Likely to deploy overlay within 3 years 20 % 1 % Market penetration 80 % 10 % deployed by 2016 Unlikely or unsure Power, space, cooling, cables, laws of physics, value of silicon
