What is SD-WAN?

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 on-going 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 SD-WAN by VeloCloud™ Edge device.

Today’s Branch Network Challenges

To stay competitive, organizations are constantly evolving to overcome branch challenges:

Expensive Bandwidth

Increasing bandwidth to existing and new branch offices is expensive and time consuming.

illus-branch-complexity-outline
Branch Complexity

Numerous single-function devices in the branch leading to device sprawl with silo management needing multiple truck rolls to deploy, monitor and troubleshoot.

Rigid Architecture

Branch WAN traffic hair-pinning through datacenter degrades cloud application performance. Provisioning new applications for branch use requires re-configuration and is IT intensive
