WAN Bonding Applications and Benefits

Digi WAN Bonding is instrumental in scenarios requiring increased throughput or availability of remote applications. By utilizing multiple connections — whether fixed network or wireless — users can enhance bandwidth and uptime, effectively avoiding issues related to line failures or network problems. Here are just a few examples of some use cases for Digi WAN Bonding:

  1. Cellular Resiliency for Vehicles:
    In the realm of public transit, uptime is paramount for both passengers and operators. Consider the scenario of a Digi TX64 5G cellular router in a transit vehicle equipped with two cellular modems (WWAN1 and WWAN2) connected to different providers. While Digi Surelink® provides failover capability, Digi WAN Bonding intelligently balances the two cellular connections based on quality metrics. As one connection gradually degrades, it is used only when the most effective connection has been saturated. This ensures continuous, reliable connectivity during the vehicle’s journey.
  2. More Bandwidth in Office Environments:
    For an office user relying on a symmetric 100 Mbps copper line, large file transfers often lead to congestion and slowdowns in the network. Digi WAN Bonding transforms this scenario by combining the symmetric wired connection with an asymmetric cellular connection. This dynamic pairing significantly increases throughput without compromising the low latency of fiber, even under heavy loads. The result is a streamlined network experience, especially beneficial for remote workers requiring VPN access to the office network.
  3. Protecting Mission-Critical Data in Remote Locations:
    Digi WAN Bonding introduces packet duplication as a safeguard for mission-critical data in remote locations. By simultaneously sending packets through all available Internet connections and transmitting only the first packet received on either end of the bonded connection, this use case prioritizes data certainty over increased throughput. It ensures that data transmissions are delivered with 100% certainty, even in scenarios involving high-latency or intermittent connections.

When a client enables the WAN Bonding feature in Digi Remote Manager and configures their Digi devices to combine their WAN and WWAN interfaces, the default route for any traffic is through the WAN Bonding application. This application then negotiates a tunnel with a virtual private server (VPS). This can be managed by the customer, by Digi Professional Services or by a Digi partner, and begins sending data to the VPS to be recombined and sent onwards. Any replies are sent via the VPS, fragmented appropriately, and sent to whichever interface the device identifies as the most performant and is not saturated. If a device sends a packet via the WWAN connection and proceeds to lose signal before a reply is possible, the VPS will send the reply through the connected WAN interface.

Use Cases for Digi WAN Bonding

Uptime in vehicles, such as buses and trains, is a major priority for many use cases. Setting up multiple cellular connections with failover through Digi Surelink helps ensure uptime if one connection goes down. However, as the vehicle moves, connections can gradually degrade in quality. With Digi WAN Bonding, multiple connections are intelligently balanced based on quality metrics such as packet loss and latency. As one connection degrades, it is only used when the most effective connection has been saturated. These benefits also make it a good solution for offices, retail, industrial, and energy companies.
