Why are operators and enterprises turning to SDN?

You are facing unprecedented business pressures to cut costs to  make up for flat revenues. But the hockey-stick growth in multimedia, cloud  applications, and mobile usage continues unabated. So how can you reconcile the  demand to cut costs with the need to compete and grow at such astounding rates?  Enterprises, carriers, and service providers like you are turning to SDN  technology as a way to handle the market pressures and change network design  and operations.

At the core of SDN, open APIs help you centrally program network  behavior through software applications. With those previously closed networks  now open, you can manage your network—all of your devices, endpoints, and  infrastructure—from a central point. It doesn’t matter how complex your network  technology is because SDN is designed to work with complex networks and make  them easily manageable and centrally run.
For enterprises, operators, and providers, SDN a number of  advantages, including:

  1. Programmable  networks: Historically, your network was only as good as the hardware that  controlled it. SDN changes all that and provides easy customizations, even down  to the individual customer level. With hardware decoupled from software, you  can introduce innovative, differentiated new services quickly—something  previously unimagined with the constraints of closed and proprietary platforms.

  2. Intelligence  and control centralized: Bandwidth management, restoration, security,  and policies have been a thorn in the side of every network operator. Now, with  those functions centrally controlled by an SDN controller that is highly  intelligent and optimized, you now have a holistic view of the network. That is  an asset to your operations, not a legacy liability. With network control centralized,  your network resources can be controlled and managed in a coordinated way to  delivery services end to end. And devices now operate with awareness of the conditions  of the network overall.
  3. Network  interaction via APIs: Your static physical hardware and network connections are a thing  of the past with SDN. Services and applications are no longer tied to network hardware  and connections. Instead, your applications connect over the network  infrastructure flexibly, with the use of APIs, between OSS/BSS, orchestration,  and assurance systems.
  4. Vendor-neutral  architectures: SDN enables an open approach that is vendor-neutral and supports a  large assortment of applications. Cloud orchestration, SaaS, and  business-critical networked apps are just a few of the possibilities SDN  enables. With SDN, intelligent network services and applications run in a common  IT environment that can control the hardware and associated technologies of  countless vendors.

Why Ciena?

The key to Ciena’s Blue Planet SDN approach is openness. Open APIs—a  seemingly simple piece of software—provide the means to encapsulate and  abstract complex tasks. With Blue Planet SDN, open REST APIs can make your back-office  OSS/BSS integration much less complex, while DevOps-style programmability gives  you greater control, agility, and self-sufficiency across functional domains.  Soon, you’re well on your way to providing innovative services such as  bandwidth-on-demand and Network-as-a-Service.

Blue Planet’s SDN is the vendor-neutral solution customers are  turning to for automating service and network provisioning and assurance across  multiple physical network layers (L0, L1, L2). This central approach to SDN eliminates  management and technology silos so you can orchestrate your services from end to  end.

The old networking approach  included a lot of manual ‘step-by-step’ provisioning errors. SDN greatly  reduces those issues and results in significantly faster service provisioning. If  you’re looking to integrate with underlying third-party SDN controllers,  EMS/NMS, and network elements, Blue Planet will simplify your life and bring  agility to your network.
