Flow duplication
Increase application resiliency by simultaneously sending mission-critical application traffic across one WAN link and duplicating it across a second link. The first flows to arrive at the desired destination are accepted. If there is congestion or even a failure on one of the WAN connections, there is no impact to the application because it is fully duplicated on the secondary connection. Flow duplication is ideal for cellular routers in vehicles, when roaming between various wireless providers or even between cellular and low-orbit satellite networks.
Quick Tip: Reserve this feature for mission-critical traffic.
Flow balancing
Improve cost efficiency by bonding two links together — often a wired link plus a cellular link — and use percentage weights to assign some traffic application traffic flows to one link and other flows to the second link. In fixed sites such as stores and mid-sized offices, flow balancing is a valuable tool to reserve metered data plans only for low-bandwidth or business-critical applications.
Quick Tip: When choosing links and configuring, be aware that if one of the two bonded links fails, all of the traffic will automatically spill over to the other link.
Bandwidth aggregation
Boost bandwidth by bringing two WAN links together into one larger, more robust path. The resultant aggregated path is a vital tool in situations where an individual link lacks enough bandwidth to carry traffic from a bandwidth-intensive application such as live video streaming from cameras aboard a police cruiser, a city bus during an emergency, or a branch office during a live-streamed company event.
Quick Tip: The latency of the aggregated bandwidth is determined by the slowest of the two links. Thus, it’s ideal to use two links with equal latency.
