Connecting your sites
SD-WAN
We connect multiple sites with a network that manages several internet connections intelligently and gives priority to critical applications.
What it is for
What SD-WAN solves
When a site depends on a single internet line, one fault at the provider stops work, and business traffic shares the same bandwidth with everything else.
Several lines at once
The site's internet connections go into a shared zone, and traffic is split between them. That way the second line adds useful bandwidth in day-to-day operation too.
Failover when a line drops
If a line goes down, the rules steer traffic to the connection that still works. Users do not have to do anything.
Critical applications first
Each application has its own setting for which line its traffic takes and at what priority. The business system or a video call still gets priority while someone is downloading a large file.
Every site from one console
We manage the devices at all sites centrally. Changing a rule does not mean configuring each location separately.

How it works in practice
A project where we combined several internet lines and also controlled traffic priority. The network was built on Fortinet devices. The university case study describes the full project.
Several providers, one SD-WAN zone
At the Hungarian Dance University, we configured internet lines from several providers into one SD-WAN zone with custom SD-WAN rules. This supports availability and load balancing.
Dynamically changing priorities
Traffic from the dormitory, the Wi-Fi network, secondary school and university teaching, the computer labs, and the studio each received its own priority, and these priorities change dynamically.
Bandwidth for broadcasts
Online broadcasts published to the internet get the bandwidth they need alongside the daily teaching traffic.

Frequently asked questions
The questions we hear most
How is SD-WAN different from a site-to-site VPN?
SD-WAN typically connects sites through encrypted tunnels, just as a VPN does. On top of that, it handles multiple lines and per-application rules, as described above. With a simple VPN built on a single line, losing the line means losing the site.
Do we need a second internet line?
For failover, yes, because with a single line there is nowhere to switch to. It is worth ordering it from a different provider, ideally over a different physical route, so that a fault at one provider does not affect both connections. The network analysis shows which sites need a new line.
What happens if a line slows down but stays up?
SD-WAN also monitors line quality, such as latency and packet loss, so it can move sensitive traffic off a connection that is degrading.
Do you also handle maintenance after handover?
Yes, under a custom agreement, within a scope agreed with the client. This can include installing firmware and software updates and backing up the configuration regularly. The details are on the network maintenance page.
