Traditional Hub-and-Spoke VPNs route all traffic through the central hub. While secure and easy to manage, this approach can introduce latency, bandwidth bottlenecks, and increased load on the hub, especially when multiple spokes communicate frequently with each other.

7G Fuse solves this problem with Automatic Spoke-to-Spoke VPN Generation, creating a dynamic, intelligent VPN mesh without any manual configuration.


How It Works

1. Spoke Authentication via Hub
  • Each spoke first connects and authenticates with the central hub.
  • Authentication ensures security and proper access control before direct tunnels are established.

2. Automatic Direct Tunnel Creation

  • Once authenticated, 7G Fuse automatically establishes secure, encrypted tunnels directly between spokes that need to communicate.
  • These tunnels use the best available WAN links at each site, including 4G/5G, fiber, broadband, or satellite.

3. Traffic Bypasses the Hub

  • After the direct tunnel is established, data flows directly between spokes.
  • The hub continues to manage security, policies, and monitoring, but traffic no longer hairpins through the hub unless needed.
  • This reduces latency and optimizes overall network performance.
Key Benefits

1. Lower Latency Between Branch Locations

  • Direct spoke-to-spoke tunnels minimize the number of hops traffic takes.
  • Critical for real-time applications like live video streaming, VoIP calls, and remote control systems.

2. Reduced Bandwidth Usage at the Hub

  • Direct tunnels offload traffic from the central hub.
  • Frees up hub resources for monitoring, policy enforcement, and hub-specific traffic.
  • Reduces network congestion and improves overall performance.

3. Improved Performance for Real-Time Applications

  • Video feeds, VoIP, industrial control systems, and IoT telemetry benefit from faster, more reliable paths.
  • Bonded WAN links at each spoke ensure high throughput and redundancy even for direct tunnels.

4. Dynamic Mesh Connectivity

  • The network dynamically adapts as spokes are added or removed.
  • No manual tunnel creation is needed, making it scalable from a few sites to hundreds of nodes.

5. Secure and Reliable

  • All direct spoke-to-spoke tunnels are AES-256 encrypted.
  • Traffic integrity and confidentiality are maintained across public or private WAN links.
  • 7G Fuse monitors link health and can reroute traffic automatically if a direct tunnel degrades.
