SD-WAN

Think of a software-defined network (SDN) as the foundation for a software-defined wide area network (SD-WAN). SD-WAN uses software and a centralised cloud-based controller to intelligently steer traffic across the WAN. SD-WAN handles traffic based on priority, quality of service and security requirements in accordance with business needs.

Unlike traditional WAN architecture, the SD-WAN model is designed to fully support applications hosted in on-premise data centres, public or private clouds and SaaS solutions such as Salesfore.com, Office365 and Dropbox, while delivering the highest levels of application performance.

 

The Solution

The Flexgrid SD-WAN solution powered by 128 Technology provides flexible and straightforward on-demand WAN interconnection with better service experience between branches, headquarters, data centres, and the cloud. With compelling features such as application-based intelligent traffic steering, optimal link selection, tunnel-less, adaptive encryption, zero-touch provisioning, virtual network segregation, QoS and WAN optimisation.

Simplicity

The SD-WAN solution provides the ability to use both standard hub-and-spoke or full-mesh topology options, all without the need for legacy tunnels. Each site can be deployed with single or multiple SD-WAN gateways connected to various circuit types. Secure SD-WAN devices can be deployed on hardware included with the service, virtual machines or in the public cloud. All managed from a centralised Cloud console by Flexgrid

Agility

The SD-WAN solution supports a variety of Zero-Touch Provisioning (ZTP) methods. This allows devices to be sent out to customer locations without complex and time consuming pre-staging requirements.

Security

The SD-WAN solution uses a Zero-Trust model where by default all traffic is denied and must be permitted by policy. Traffic authentication is provided on a hop-by-hop basis and all traffic can be controlled via the distributed Firewall which is FIPS-140-2 certified, ICSA and PCI certified.

128Technology Security

The SD-WAN solution uses adaptive encryption on each device to inspect traffic and determine if the data about to be sent over the WAN has already been encrypted. When encrypted, the adaptive encryption feature avoids the delay and performance impact of unnecessary double encryption. This dramatically increases the performance and efficiency of the overall solution.

Performance

The SD-WAN solution monitors the performance of applications flowing through the WAN using active monitoring. This traffic monitoring method measures the actual traffic and applications flowing across the customer network instead of simulated traffic between routers. This method provides improved visibility of issues and policy control. The lack of a traditional IPSEC tunnel model coupled with other enhancements can remove packet overhead resulting in 30-50% bandwidth saving.

Savings

The combination of the cost-efficient service-oriented SD-WAN solution, adaptive tunnel-less encryption and WAN connectivity options provided by Flexgrid demonstrate considerable savings compared to other Enterprise-class SD-WAN solutions.

Our SD-WAN solution is delivered as a cloud service bringing automated operations and service levels to the WAN edge, and when used in conjunction with Juniper Mist wired and wireless devices, we can provide a single platform to manage both the LAN and the WAN as one.

Get Technical

SD-WAN applies the principles of software-defined networking (SDN) to a business WAN connection; separating the data plane and control plane of the network and abstracting it into a virtualised service.

The architecture of SD-WAN virtualises numerous components of a traditional legacy network (e.g. secure routing, application optimisation, quality of service) and centralises the network management via a cloud-based “orchestrator” which intelligently controls traffic flows across the corporate network.

Leveraging the powerful application identification engine and link quality detection engine, the SD-WAN solution can provide intelligent traffic steering based on the application priority, link quality, load balancing, and bandwidth utilisation.
