How SD-WAN works

SD-WAN creates a virtual WAN (wide-area network) through a centrally controlled overlay that lets you manage and deploy branch-office services across your organisation. 

 
 
 
 
 
 
 
 

1. Creating an overlay network

SD-WAN allows you to simplify your WAN infrastructure by replacing legacy branch routers, giving you full visibility and control of everything happening across your network at an individual application level – all from one virtual dashboard.

 
 
 
 
 
 
 
 

2. Introducing application awareness

Unlike most traditional networks, SD-WAN understands individual applications – including any service level agreements (SLAs) – and automatically creates network policies for them, constantly monitoring each application to optimise performance. 

 
 
 
 
 
 
 
 

3. Providing a policy-based framework

The network policies SD-WAN creates are adaptive, updating in real time based on current business needs. And because your technical staff can monitor and control every policy and application from a central platform, it reduces the strain on your IT department.

Your SD-WAN migration journey

The diagram below shows how we migrate you from your traditional network (on the left) to SD-WAN (on the right).

We use resilient service gateways between your existing MPLS (IPVPN) network and your new SD-WAN network, ensuring a seamless transition and uninterrupted site-to-site communication.
