The Site-to-Multi-Site VPN is an evolution of the traditional VPN model. Instead of just connecting two networks, 7G Fuse allows a central hub to securely connect multiple remote sites or mobile clients (spokes), forming a scalable, flexible, and secure VPN architecture.

This architecture is particularly effective for distributed enterprise environments, surveillance networks, retail chains, mobile units, or industrial IoT sites, where managing multiple VPNs individually would be complex, inefficient, and error-prone.

How It Works?

Central Hub
  • The hub is the core VPN server, usually located at the headquarters, data center, or main operational site..
  • It manages authentication, encryption, routing policies, and traffic scheduling for all connected spokes.
  • Acts as the central point of control, enabling network-wide visibility and security.

Remote Spokes

  • Remote offices, mobile units, or devices connect as spokes to the central hub.
  • Each spoke maintains independent multi-WAN bonding, allowing it to aggregate bandwidth from multiple links (4G/5G, fiber, broadband, satellite).
  • Even if some links degrade, the spoke continues to operate at optimal performance.

Secure Connectivity

  • Every spoke connects to the hub using AES-256 encrypted VPN tunnels.
  • Each connection is authenticated and monitored, ensuring data integrity and confidentiality across public or private networks.

Traffic Management

  • 7G Fuse intelligently monitors WAN links for each spoke.
  • Traffic is bonded, load-balanced, or redundantly transmitted as needed to ensure.
    . Maximum throughput
    . Minimum latency
    . Zero packet loss
  • Dynamic routing ensures traffic takes the fastest and most reliable path to the hub or other spokes (if direct spoke-to-spoke tunnels are enabled).

Benefits for remote sites

  • Independent Multi-WAN Bonding:
    Each remote site can use multiple WAN connections simultaneously, ensuring uninterrupted service even if a single link fails.
  • Centralized Security Policies:.
    The hub enforces firewall rules, traffic segmentation, and encryption policies consistently across all spokes.
  • Simplified Deployment and Management:
    • Configure once at the hub, and all spokes inherit policies automatically.
    • No need for manual configuration at each remote site.
    • Ideal for networks with tens, hundreds, or even thousands of remote locations.

Advanced Feature

  • Dynamic Traffic Optimization
    • The hub monitors each spoke’s link quality in real time.
    • Traffic is routed dynamically based on bandwidth availability, latency, and packet loss, ensuring that applications like video streaming, VoIP, or IoT telemetry always perform optimally.
  • Automatic Spoke-to-Spoke Tunnels
    • If required, the hub can automatically create direct encrypted tunnels between spokes, bypassing the hub for certain traffic.
    • This reduces latency and bandwidth usage at the hub.
  • Scalability
    • Supports from a few to hundreds of remote spokes, making it suitable for small enterprise networks or large-scale distributed operations.

Ideal Use Cases

  • Enterprise Branch Networks:
    Connect multiple branch offices to the headquarters securely and efficiently, with bonded WAN links at each branch.
  • Surveillance Camera Clusters:
    Connect thousands of cameras or IoT sensors to a central monitoring hub, ensuring real-time video transmission without drops.
  • Retail Chains:
    Connect multiple retail outlets to a central ERP, payment, or inventory system over high-performance bonded VPNs.
  • Distributed Industrial Sites:
    Monitor and control remote production units or IoT-enabled equipment over secure, high-reliability VPN links.
