1 HOW SDN AND (NFV) WILL RADICALLY CHANGE DATA CENTRE ARCHITECTURES AND ENABLE NEXT GENERATION CLOUD SERVICES Brian Levy CTO SERVICE PROVIDER SECTOR EMEA JUNIPER NETWORKS

2 CIO DILEMA IT viewed as cost center Line of business owner needs agility Transform IT into profit center & innovate Powered by Cloud

3 CLOUD DRIVES AGILITY PRIVATE CLOUD 72% Only 11% no plans to deploy private cloud** APPS IN THE CLOUD PUBLIC CLOUD $54.5B $131B 19% CAGR* 17% CAGR* Virtual Virtual Virtual Physical Virtual My on-premises data center Physical Virtual Physical My managed service provider Virtual Physical My hosted service provider * Gartner, June 2013, Public Cloud Forecast ** Gartner, Sept 2013, Private Cloud Matures, Hybrid cloud is Next My cloud service provider

4 NEW ENTERPRISE APPS - NEW ARCHITECTURE Technology architectures must better support increasingly dynamic operational and business processes SILOS SCALE UP SCALE OUT APPLICATIONS Tightly coupled Client/server App performance Big data, real-time analytics Self-service COMPUTE Specialized hardware Virtualization, automation Large & dynamic workloads, mobility STORAGE Storage tied to physical infrastructure SAN/NAS Converged Network Distributed storage NETWORK Closed, Proprietary Physical network Integration with cloud, mgmt tools Dynamic network, Automation, x-domain virtualization Last 10 years Last 3 years Now and future

5 NETWORK WAS NOT DESIGNED FOR CLOUD 100% VIRTUAL COMPUTE 46% Share of virtualized servers and storage is growing rapidly VIRTUAL COMPUTE 71% 0% Time PHYSICAL COMPUTE 54% but, networks are still designed to connect Physical Hosts and Physical Networking Services PHYSICAL COMPUTE 29%

6 LIMITATIONS OF CURRENT APPROACHES TO NETWORKING IN THE CLOUD INTER-CLOUD ORCHESTRATION Inability to orchestrate multicloud/hybrid cloud environments SERVICE INSERTION Appliance-based network functions limits service velocity SCALABILITY Tying per-tenant information to physical network restricts scale PROGRAMABILITY No programmatic API at the network level for integrated orchestration

7 CLOUD CHARACTERISTICS ELASTIC. ON-DEMAND. AGILE.

8 NETWORK CHARACTERISTICS SPEED. ALWAYS ON. HIGH PERFORMANCE.

9 THE QUESTION How to get the best of both worlds? ELASTIC. ON-DEMAND. AGILE. SPEED. ALWAYS ON. HIGH PERFORMANCE. How to increase the agility of the network, without breaking what is good?

10 EVOLUTION OF NETWORK VIRTUALIZATION VLAN APPROACH OPENFLOW REACTIVE APPOACH PROACTIVE SOFTWARE OVERLAY Manual End-to-End VLAN configured on physical switches Reactive End-to-End Requires programming of flows Virtual Network Overlays Automated network provisioning with the ability to run on top of any physical network

11 NETWORK VIRTUALIZATION JOURNEY VLAN Tenant state embedded in the physical network Manual configuration of VLANs at every switch Performance Management, Scale Tenant IDs Service insertion is complex MANUAL. INEFFICIENT. LOW SCALABILITY.

12 NETWORK VIRTUALIZATION JOURNEY Reactive OpenFlow Approach Controller becomes the choke point Centralized Openflow Controller Per-Tenant state in the physical network OpenFlow needs to be supported in the physical network HIGH LATENCY. LOW SCALABILITY. NEW FAILURE MODE. FORK-LIFT UPGRADE.

13 NETWORK VIRTUALIZATION JOURNEY Proactive Software Overlay Networks Logically centralized and distributed SDN 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.

14 CONTRAIL FUNCTIONALITY 4 key Components of the Contrail Family Contrail SDN Controller Contrail Controller Open, Standards-based Controller Controller Analytics Contrail Analytics Virtualized Server vrouter IP fabric (underlay network) Virtualized Server vrouter Real-time analytics engine on various protocols between any network Contrail vrouter QFX, Q-Fabric, EX engine which handles the forwarding plane work on the compute node MX-3D/EX9200 (Gateway Element) Gateway Element MX Series (or other router) or EX9200 can serve as a gateway eliminating the need for a SW gateway & improving scale

15 CONTRAIL - FEATURES ANY Open Cloud Platform VIRTUAL NETWORK CONTRAILCONTROLLER VIRTUAL NETWORK OVERLAY Routing Switching Gateway Services IPAM, Virtual DNS Load Balancing Rich Analytics Service Chaining Security ANY Hypervisor ANY Physical Network High Availability Elastic, Resilient VPN REST API

16 NETWORK RESPONDS TO APPLICATION APPLICATION Continuous Network, Infrastructure Feedback Resource Orchestration Analytics Compute & Storage Provisioning Infrastructure Events, Logs, Statistics Automated & Orchestrated Network Networking Services Orchestration Virtual Network Provisioning Policy & Security Framework

17 WHAT ABOUT THE PHYSICAL NETWORK? Increased agility? Automation? Orchestration? Yes, Yes, Yes

18 AN ANALOGY Cars for the last 100 years Cars today. Manual everything transmission, radio, heat, etc Automatic climate control, back up sensors, lane change warnings, GPS, etc. Make the network easier to drive without taking away control.

19 SOFTWARE DEFINED NETWORK? SDN is the Brains of the network it is the part that creates service contexts for use within the network A service context is a service delivered over an infrastructure to a requester, here the requester could be a person, device, other network provider, application etc SDN is responsible for the lifecycle management of that service context from birth to death In SDN architectures the Brains are logically centralised and have domain over a given infrastructure SDN goes beyond human capacity with SDN you can have more than one Brain but the Brains or Controllers need to be synchronised if they are managing the same infrastructure

20 THE ETSI NFV FOUNDATION ARCHITECTURE Juniper is an active supporter of the ETSI Network Functions Virtualisation Initiative. We recently hosted the forums plenary meeting in our campus in Sunnyvale with over 350 attendees from 155 companies attending. Juniper is providing regular technical contributions to the forum and working with the industry to develop the architectural framework for the future

21 NETWORK FUNCTIONS VIRTUALISATION? NFV or (Network Functions Virtualisation) is the virtualisation of functions within the network. Today we have individual physical boxes within communication networks for particular functions NFV uses the same techniques that have been used in IT systems for years to create virtualised compute and storage architectures, however, in this case we are virtualising network functions such a firewalls, routers etc The effect of NFV will be profound on network infrastructures as now we are redefining the way communications functions are actualised and scaled Having network functions on demand, scalable and flexible within networks will be the most important change driving new network designs in the coming years

22 INTRODUCING THE HI IQ NETWORK Empowering End Customers With Customization OPERATIONS AUTOMATE Simplicity and Agility INFRASTRUCTURES SCALE Performance and Efficiency SERVICES CREATE Intelligence and Programmability

23 THE HI IQ NETWORK OUR VISION Networks where the functionally and not just the bandwidth of the infrastructure can be dynamically changed as needed to meet differing demands and to bring new services to market in minutes rather than months This is an network infrastructure that is able to adapt to different demands placed upon it with a level of flexibility way beyond the networks of today. It is an infrastructure that is application aware, self learning and intuitive, where the capabilities of the network can be adjusted in real time to provide the best level of user experience for the customer and the greatest levels of efficiency for service provider
