2 JUNIPER AND SDN IN THE NEWS 2 Copyright 2013 Juniper Networks, Inc.

3 WHY DO WE NEED SOFTWARE DEFINED NETWORKING? Manual Configuration Static Networks Network Services Business Applications Centralized configuration at a the service level. Ability to deploy new services quickly. Elastic virtualized network services. Make the network meet the needs of the business applications. More Manageable & Simple Networks More Flexible & Agile Networks More Cost effective & Elastic Networks More Business Aligned Networks 3 Copyright 2013 Juniper Networks, Inc.

4 JUNIPER'S SDN STRATEGY: SDN Principles Separate Planes Centralize Use the cloud Common Platform Use Standards Apply Broadly 4 Juniper Steps Centralize Management 1 New Licensing Model Extract Services Centralize Controller Optimize the Hardware JUNIPER SOFTWARE ADVANTAGE Full Use/Elastic Transferable Software Lifetime Assurance 4 Copyright 2013 Juniper Networks, Inc.

5 THE SIX SDN PRINCIPLES Separate networking software into 4 planes Forwarding, Control, Services and Management Centralize Management, Services and Control Planes Use the 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 Providers Mobile and Wireline Optimize each network element Simplifies network design and lowers OPEX Reduce time to service and correlate cost based on value Enables new business solutions Provides choice and lowers cost Flexibility and new business opportunities 5 Copyright 2013 Juniper Networks, Inc.

7 1 ST STEP TO TRANSITION TO SDN CENTRALIZE MANAGEMENT Command Line Interface Low level of abstraction ("How") Single device view Manual, time consuming Error prone Does not scale Centralized Management High level of abstraction ("What") Network wide view Automated, fast Cross-device consistency Scalable 7 Copyright 2013 Juniper Networks, Inc.

8 1 ST STEP TO TRANSITION TO SDN: CENTRALIZE MANAGEMENT JUNOS SPACE Junos Space Centralized, Automated Network Management Junos Space Network Management Platform EMS with extensive FCAPS, provisioning, and automation Junos Space Management Applications Security Director, Service Activation Director, Network Director, Service Now, Service Insight, Content Director, More... Junos Space SDK Open programmable interfaces. Easy integration with 3rd party applications and OSS / BSS / MoM. 8 Copyright 2013 Juniper Networks, Inc.

9 2 ND STEP TO TRANSITION TO SDN EXTRACT SERVICES Deploying physical service appliances is expensive and complex LB Firewall DPI VPN Cache Lots of boxes Complex deployment Inflexible 9 Copyright 2013 Juniper Networks, Inc.

10 2 ND STEP TO TRANSITION TO SDN: EXTRACT SERVICES SERVICE VIRTUALIZATION AND CHAINING Run network services in virtual machines on x86 hardware Steer flows of traffic through chains of services Cost savings due to uniform COTS hardware for all network services (and other applications) Elastic service plane and other virtualization benefits (e.g. snapshots) Faster time-to-market, more agility Chain of virtual services Router Evolved Packet Core Firewall DPI Cache NAT Router 10 Copyright 2013 Juniper Networks, Inc.
