Every business, especially if you are running numerous branches or employees to serve customers, requires connectivity to run it smoothly. And only connectivity is not enough, you require secure connectivity with end-to-end visibility without adding complexity. SD-WAN (Software Defined WAN) can help business to optimise the bandwidth as well as reduce the WAN cost as it offers point-to-point solution.

It is an appliance based symmetric solution in which one appliance sits at the data center and another at the branch offices. Thus, if any traffic comes to any branch office, it does link bonding, so whatever type of connectivity your different offices has; for instance one is using high-speed broadband connectivity with more than 20 mbps of speed, while another one has only 2 mbps speed, it will bind all the links and provide one tunnel to the branch. And within this tunnel it offers secure connectivity from point to point.

It’s more of Application Aware Virtual WAN that understands and continuously measures and monitors each link for loss, latency, jitter and congestion. It intelligently understands the incoming link and accordingly makes decision to route that. Citrix has developed the solution called NetScaler SD-WAN which maintains the performance across the branches for mission critical applications even when a network link fails. It helps to improve the virtual desktop experience to branch-office and mobile users and accelerate traditional enterprise applications. Even if the business has low cost broadband connections, it can expand WAN capacity while maintaining MPLS-level quality and reliability. It supports cloud migration with integrated security to protect enterprise data. The cloud offers sheer security as it has strong encryption, application- level security policies and data segmentation.

The end to end solution lets the admin manage the entire branch offices from one central location. as well as there are numerous tools which raise the flag in case of any error or problem so within no time admin would get the notification about the same with complete details.

Benefits of SD-WAN

It ensures any application which is being used by the business and provides for it to be available to the user and the branch up and running 24/7/365. It reduces TCO on the spending particularly on the bandwidth by up to 80%, accelerates and improves performance of the application by minimum 2 to 3 times and provides central management and visibility without any limit of number of branches. IT check tunneling (Point to point) ensures complete encryption of data using 256-bit AES or FIPS compliant IP-SEC encryption. It offers sheer security to the data any time it leaves the enterprise boundary, optionally encrypting even on private networks.
