Jump-start your understanding of SD-WAN

What is SD-WAN and what does it do?

It connects locations regardless

of underlying network

It puts traf�c onto most appropriate

paths for best performance

It creates and oversees a secure,

reliable ‘overlay’ network

The truth: They can co-exist because the quality of an underlay network such as MPLS supports the quality of an SD-WAN overlay network. SD-WAN enables you to of�oad traf�c for social media and video apps to the internet, leaving more room on the MPLS underlay network for your important business apps.

The truth: Cost reduction is just one driver for SD-WAN as it enables you to manage your WAN through software. But there are other drivers which include: ef�cient bandwidth optimisation, improving apps performance at your branches through traf�c prioritisation over the Internet, acceleration of branch deployment with IT automation tools to support greater speed to market.

The truth: By moving branch traf�c off the MPLS network and onto the Internet, there will be more threat points to manage. Whilst SD-WAN enables you to set up network-wide business and security policies, other potential areas of vulnerability can still exist. So it’s important to consider additional security such as end-point security, security services at the branch, next generation �rewalls and security monitoring services.

Assess your current network performance and management1

1

Do you have full visibility of your business apps and where they are stored?

Are you suffering from slow applications or high latency on your network?

How much time are you spending on manual network changes for your remote sites?

How critical are bandwidth hungry apps like voice, media and video to your business?

Determine if your network is ready to deliver on your digitisation strategy

When it comes to assessing your SD-WAN and business requirements, you’ll need to consider security.

That’s why it’s important to �nd a trusted solution provider who understands the importance of imbedding security into the network architecture and who cares about the underlay network.

What are the potential impacts on your security and architecture if you of�oad network traf�c to the internet?

Is your organisation planning to move workloads into the cloud?

How quickly can your network enable your existing and new apps for staff?

What impact would an outage at one or more of your sites have?
