Ensure application QoS by prioritising traffic and bonding bandwidth.
Add additional bandwidth to your network when you need it. Exinda SD-WAN lets you plug additional broadband lines to increase your network capacity.
Get more performance from your network bandwidth
Organisations rely on Internet connectivity. Without robust connectivity, your business may face disruptions caused by link failures or WAN blackouts. These can be costly.
As your organisation pushes more data than your Internet pipe can handle, application performance begins to suffer. Users start complaining about latency with frozen or faulty applications such as voiceover IP or video conferencing. Introducing Exinda SD-WAN a simple, cost-effective, set up and forget solution to these problems. Exinda SD-WAN is the latest addition to the Exinda family.
With Exinda SD-WAN, you can combine and manage up to twelve Internet connections into a single, robust ultra-high speed line via a bonding tunnel. Broadband bonding is inherently more reliable and about 70% less costly per month compared to a single MPLS link.
You can boost overall performance while keeping costs down. When a Wan link fails, it disrupts all the application flows that are going through that Wan link, which usually results in the sessions being dropped.
However, thanks to the overlay tunnel technology of Exinda SD-WAN, the application flows can be kept alive even during Wan blackouts or brownouts, providing seamless session continuity. Your users won’t even notice that there was an issue with one of the lines.
Another benefit of Exinda SD-WAN is that it lets you add bandwidth easily to your network when you need it. New broadband lines can be simply plugged into the device to increase your network capacity.
When you rely on a single service provider, you are dependent on a single SLA. By aggregating service providers, you can build your own best-in-class bandwidth solution.
Intelligent Wan automation is at the heart of Exinda SD-WAN. The overlay tunnels leverage advanced algorithms to monitor, remember, learn and react to your network traffic in real-time and on the packet level.
Services such as live video, VoIP, chat applications, file transfers, or any other types of specific application flows are mapped onto corresponding overlay tunnels.
Since the overlay tunnels optimise according to the metrics that matter for the flow type, such as latency throughput jitter or packet loss, liability predictability and overall performance of these services improved by orders of magnitude without requiring any human intervention.
Exinda SD-WAN Feature Summary
Define your multi-element WAN

Exinda SD-WAN Features In Detail
A WAN link failure disrupts the application traffic flowing through that link. With the appropriate Exinda SD-WAN overlay tunnel, you can shield applications from blackouts in near real-time without affecting the application SLAs. Traffic moves automatically and seamlessly to a fail-over state without requiring users to re-start sessions, or causing a disruption of services from traffic moving to new WAN IP addresses.
Sticky routing is the ability for a traffic flow to be re-assigned onto the original WAN path once that WAN is restored from a blackout. Exinda SD-WAN both provides both sticky and non-sticky routing as configuration options.
WAN brownouts are more common and challenging than WAN blackouts. The WAN path still has connectivity, but performance is degraded with packet loss, increased latency or jitter.
Exinda SD-WAN overlay tunneling technology performs in-band and out-of-band measurements in both path directions. It measures packet loss, one-way delay as well as more advanced metrics such as recent history of the path performance. It uses such metrics to make the best decision at a per-packet level to steer an application’s traffic. This detects brownout risk and mitigates it by steering traffic to more optimal paths in real-time.
Exinda SD-WAN overlay tunnels can monitor one-way metrics of various characteristics of the available paths, including the recent performance history, as well as the more direct measurements of packet loss, latency and peak rate. The overlay tunnels leverage advanced algorithms designed for different application flows to optimize application performance over the multiple WAN paths.
Exinda SD-WAN combines traffic shaping for inbound/outbound traffic with dynamic bandwidth reservations. Bandwidth reservation carves out guaranteed bandwidth for different types of traffic flow when they are detected in the network. If not present, the reserved bandwidth is released for consumption by other types of traffic flows.
Application-specific overlay tunnels orchestrate WAN resources to work around networking problems without needing human intervention. Exinda SD-WAN assesses various transport parameters to retain WAN connectivity using virtual networks over preconfigured tunnels.
Exinda SD-WAN bonds multiple WAN links—which may be from different service providers and different technologies (3G, 4G, 5G, DSL, MPLS etc)—into a single ‘pipe’. This enables more bandwidth, lower latency and increased reliability (redundancy). Such bonding is done automatically and transparently for applications on the network, enabling a true SD-WAN enterprise solution for both small and larger organizations.
