SD-WAN

Take Control of the Network

SD-WAN is the ability to bring application awareness and application control to the network and then to be able to run those same applications securely over any underlying network infrastructure.

What is all this hype about SD-WAN?

The importance of accurately predicating the impact of application changes to the network, the flexibility to accommodate change and avoiding customer complaints due to slow performance are just three of the potential challenges Network Managers face.

With SD-WAN adoption expected to accelerate over the next few years, there are many questions within organisations as to how this technology will improve visibility and performance, and what steps need to be made to separate fact from fiction and take advantage of the benefits and cost savings of this next generation networking technology.

With the trend of SD-WAN adoption expected to accelerate over the next few years, there are questions across organisations as to how this technology is expected to improve visibility and performance and what steps need to be made to demystify and take hold of the benefits and cost savings of this next generation networking technology.

We’re not just
talking about it!

Axians have already designed and deployed a full SD-WAN environment for a large Global organisation including the full migration of existing services across 60 sites throughout the UK and across Europe.

Whether you are a Communication Service Provider looking for an agile new service offering, or an Enterprise looking for increased agility and visibility, Axians can help with a wide range of services to help our customers on their SD-WAN journey from initial assessments and consultancy, to assisting with service creation and definition, as well as how best to integrate their own services with this new technology.

These offer opportunities to, improve operational efficiency, enhance interaction with customers and stakeholders and cut costs. Many processes can be automated to cut complexity as well as to remove the risk of human error and enhance security. This increased functionality can aid in the timely launch of new services and the empowerment of customers through self-service portals.

So, what are the 5 key pillars of SD-WAN?

Transport Independent

SD-WAN is an Overlay technology that allows you to build networks over any underlying network infrastructure, which means that it will run happily over Residential or Business Broadband, MPLS, 4G and even satellite, or any combination of those. This flexibility means increased freedom of choice for the user and the potential of significant cost savings.

Intelligent Path Control

Different applications can have different requirements in terms of how they get from A to B and each application is affected by this in different ways. For example email is not really time sensitive and as long as it gets to the recipient it is deemed to be working correctly. A CRM or ERP system on the other hand may have quite tight requirements in respect to end to end transfer and as such requires a better service than email. SD-WAN’s inherent application awareness capability allows the user to identify the applications and then to tune the network to handle individual applications based on what that application needs to operate efficiently.

Analytics and Visibility

Information is Power! As SD-WAN is ‘application aware’ it can identify, collect insight on application use together with application end to end performance enabling the creation of useful and granular report information. It tells you how the network is performing from an application perspective which means that an organisation can ensure that the network is optimised to support the business correctly.

Secure Connectivity

SD-WAN provides an encrypted secure overlay that enables the transfer of confidential application traffic over public unsecured infrastructure such as the Internet. This means that irrespective of the underlying network path the security posture is consistent.

Zero Touch Provisioning

SD-WAN is typically managed and operated from a central management/orchestration platform with minimal physical configuration being needed on each end-point. Hardware needed for site can be couriered to the location and as long as a transport network, such as MPLS or basic internet, is available then the operational configurations can be pushed down from the central controller automatically with no requirement on site other than basic device connectivity and power. This means faster rollout of new sites or services i.e. faster time to market for an organisation. Additionally it may also help to reduce OPEX through simplification of the installation.

What is the Axians approach?

The Axians approach is to start by understanding the business aims and use cases for each customer organisation and to then help ensure that the network becomes an asset that is aligned to achieving these. We use our expertise in planning, building and managing carrier-grade networks to enable our customers to take advantage of the latest technology to meet their business objectives.
