PowerLink — keep the session alive
Bond and fail over across multiple carriers so voice, video and critical apps ride through a link failure without dropping

Why it matters
Outages shouldn’t drop calls
Every internet link fails sometimes. When a site depends on a single carrier, a cut cable or a provider outage stops payments, drops calls and takes cloud applications offline until it is fixed. Basic failover helps, but switching links usually breaks every active session.
PowerLink bonds multiple links, such as fibre, broadband and LTE or 5G, and fails over between them in under a second, so sessions survive when a carrier blinks. Bonded links add usable bandwidth, each application is steered over its best path, and you can see the health and cost of every carrier.

How it works
How PowerLink keeps a site online
1
Connect
Plug fibre, broadband and an LTE or 5G backup into the Hermes edge.
2
Bond
PowerLink combines the links into one resilient connection.
3
Steer
Each application is routed over its best available path.
4
Fail over
When a carrier drops, traffic moves in under a second.
Link bonding combines several internet connections into one logical connection, so a site gets more usable bandwidth and keeps working if one link fails.
PowerLink fails over in under a second, so active sessions such as calls and video survive when a carrier drops.
