Software Defined WAN
Connectivity between multiple sites via a secure, resilient and highly-visible SD-WAN network that is optimised for the cloud
Developments in software have changed how we live and work. With more processes being automated through software, it was only a matter of time before software-defined networks gained in popularity. Along with providing cost reductions, Viatel’s SD-WAN solution provides a virtual private network between diverse sites but differentiates itself from MPLS VPNs by providing much more flexibility and visibility.
SD-WAN is a cloud-based technology that centralises the configuration and management of WANs. Control and monitoring of the network are done through a single-pane-of-glass (dashboard) that is easy to use for unified reporting across all sites.
Some additional benefits of implementing an SD-WAN solution include:
While MPLS networks need to be built on On-Net (Viatel-provided) connections, SD-WAN can be configured across a variety of mediums – MPLS, Internet, 3G/4G; On-Net or Off-Net. This flexibility means that an SD-WAN solution can be rolled out quicker than MPLS and transient/mobile sites & users can easily connect to the VPN.
The centralised network provides visibility and control of the application traffic across the network. Quality of Service in SD-WAN goes beyond that of MPLS. Traffic identification can be done at layer 7 through Deep Packet Inspection, as well as traditional Layer 3 QoS. This allows for very granular traffic shaping as well as intelligent bandwidth management – prioritising business-critical traffic and applications.
Intelligent Path Control
With most MPLS deployments, the secondary / backup connection to a site is usually left idle or carrying minimal traffic while the primary is active. SD-WAN allows you to make better use of the uplinks available through dynamic policy and performance-based path selection. Automatic load balancing can be used for maximum network performance and reliability.
Viatel uses SD-WAN security appliances integrated with Cisco security threat defence technologies. IPSec VPN technology is used to ensure secure communication with cloud applications, remote offices, or datacentres.
The SD-WAN solution pushes security to the edge where advanced security features like next generation firewall, IDS/IPS, malware protection and geo-IP based firewall strengthen network perimeters.
