Software-Defined Wide Area Networking (SD-WAN) is a transformational approach to simplify branch office networking and assure optimal application performance.
Unlike traditional WANs, SD-WAN delivers increased network agility and cost reduction. Software-Defined WAN has its roots in Software-Defined Networking (SDN), the underlying principle of which is to abstract the network hardware and transport characteristics from the applications that use the network.
Advantages of SD-WAN Solutions
SD-WAN solutions provide the software abstraction to create a network overlay and decouple network software services from the underlying hardware.
Simplify Branch Network
Provision branch offices faster with automated zero-touch deployment, simplified configuration, orchestration and ongoing monitoring with centralized troubleshooting tools. Simplify branch infrastructure with the ability to insert network services on the branch edge, in the cloud or in the regional and enterprise data centers.
Optimize Application Performance
Optimize application performance over Hybrid or Internet links with direct, secure access to enterprise and cloud applications. SD-WAN provides consolidated monitoring and visibility across multiple WAN links and service providers.
Deliver Branch Agility
Enable multiple links, devices and services to coexist and interoperate with incumbent solutions and make the branch agile. APIs enable integration into various management and reporting systems deployed by enterprises today.
Reduce Costs
Deliver Hybrid WAN with ease and enable branch offices with ordinary broadband as enterprise-grade WAN. Reduce hardware-delivery costs by choosing from deployment options such as virtual-machine on a commercial-off-the-shelf (COTS) device, virtual machine on an existing x86-based router or a purpose-built VMware NSX® SD-WAN by VeloCloud™ Edge device.
Your SD-WAN Questions Answered
Whether you are familiar with SD-WAN or are just getting started, here you will find the answers to the common questions surrounding this technology.
Have you already deployed a Hybrid WAN?
Your Hybrid WAN already leveraged both MPLS and Internet circuits at all business locations, and gave you efficiencies in route selection and business application performance by selecting Internet paths for some traffic—but it also left some frustrated users in its wake, victims of inconsistent network response.
Your Hybrid WAN deployment eased traffic congestion and delivered efficiencies from your investments in bandwidth. Yet specifying policies to steer the right application traffic over the right circuit at the right time continues to be a challenge, even knowing what traffic went where is often not easy to ascertain.
How do you get SaaS traffic to its destination without taking it on a trip full of unnecessary hops?
Do you think you might need an SD-WAN?
A Software-Defined WAN (SD-WAN) is a transformational approach to simplify branch office connectivity and networking to achieve:
Assured application performance: Transport-independent performance for the most demanding applications by leveraging the most economical bandwidth available.
Business policy automation: Simplified IT operation, offering zero-touch deployments and one-click service insertion.
Managed on-ramp to cloud: Direct SaaS cloud access with performance, reliability and security.
SD-WAN technology provisions virtual overlays and moves network management into the cloud, limiting costly on-premise equipment and distributed policy management.
Get more out of your WAN with cloud.
An SD-WAN delivers increased network agility and cost reduction.
The Cloud WAN virtualizes every network function and delivers it as a service, including core network functions such as packet steering and path selection. Having your SD-WAN delivered by the cloud can invigorate your WAN architecture to deliver increased branch office agility, orchestration simplicity, and SaaS application performance for every user at every location.
When the cloud is the network, you build and manage a secure WAN over any physical connectivity from any site, with all traditional network functions delivered as cloud services, and without the headache of complex hardware configurations for every site.
