SD-WAN Network Monitor service

The SD-WAN Network Monitor service is a tool designed to determine upload and download speeds. Speed tests can be conducted either on-demand or according to a predetermined schedule, measuring upload and download speeds of up to 1 Gbps. The results of the tests can be used as reference for various applications, including the following:

Configuring the estimated bandwidth of an interface, which can be employed in conjunction with various WAN intelligence strategies. See Using speed test results with SD-WAN for more information.
Configuring the inbandwidth and outbandwidth of an interface for use in traffic shaping. See Using speed test results with traffic shaping for more information.
Applying the speed test to dialup VPN tunnels in a hub and spoke deployment to conduct traffic shaping.

FortiOS offers a variety of methods for testing SD-WAN speed. The following table provides a brief overview of each method and guidance on when it might be most advantageous to use one method over the others.

Service	Overview	License
CLI speed test	Provides the most flexibility and options, which enables the speed test to operate with user-defined parameters. Results can be used as reference to manually add to the interface's estimated bandwidth, or inbandwidth and outbandwidth. Server is on the cloud, which is maintained by Fortinet.	Requires a valid SD-WAN Network Monitor license.
GUI speed test	Downloads the speed test server list automatically. Results can be added to the interface's estimated bandwidth with one click. Results are automatically updated in the interface `measured-upstream-bandwidth` and `measured-downstream-bandwidth` fields. Results can be used as a reference to manually configure an interface’s inbandwidth and outbandwidth. Easier to use. Server is on the cloud, which is maintained by Fortinet.	Requires a valid SD-WAN Network Monitor license.
Scheduled interface speed test	Speed tests can be scheduled to run automatically. Results are automatically updated in the interface `measured-upstream-bandwidth` and `measured-downstream-bandwidth` fields. Results can be used as a reference to manually configure an interface’s inbandwidth and outbandwidth. Possible to temporarily bypass the bandwidth limits set on the interface and configure custom maximum bandwidth limits. Server is on the cloud, which is maintained by Fortinet.	Requires a valid SD-WAN Network Monitor license.
Speed test from hub to spoke	Server is the spoke. Tests initiated from the hub. Results are cached for future use. Results can be dynamically applied to the dialup tunnel for egress traffic shaping. Results can be used as a reference to manually configure an interface’s inbandwidth and outbandwidth.	License not required.
Speed test from spokes to hub	Server is the hub. Tests initiated from spokes, even when a spoke is behind a NAT device. Results are cached on the spoke for future use and sent to the hub. Results can be dynamically applied to the dialup tunnel for egress traffic shaping. Results can be used as a reference to manually configure an interface’s inbandwidth and outbandwidth.	License not required.
