SD-WAN

How it is used

Said 'S-D-wan'. Companies deploy, migrate to and roll out SD-WAN; engineers set application policies, for example sending video calls over the link with the lowest latency. Branch devices are often installed with zero-touch provisioning: someone plugs them in and they download their own configuration.

Example sentences

1. Since we moved to SD-WAN, a single broken line no longer stops sales at a branch.

2. The SD-WAN policy sends voice traffic over the fibre line and backups over 4G.
