Linxa SBC and Switch

Linxa’s next generation carrier-grade Class 4 Switch provide a robust, high-performance, scalable signaling and call control platform, first choice of leading operators around the globe.

Load Balancer

  • Load Balancer distributes traffic between Signaling Servers. Active/Hot Standby functionality provides 100% redundancy without any session loss.
  • Ability to handle unlimited Call Attempts Per Second (CAPS) due to scalable architecture.
  • Active/Hot Standby functionality provides 100% redundancy without any session loss.
  • Sessions are replicated to the Hot Standby node in real-time. Switch-over is established using floating IP.
  • Trunks are automatically provisioned through Routing Servers.
  • Built-in firewall is also automatically provisioned through Routing Servers.
  • No requirements for inter-machine trunks even in geo-redundant clusters, due to node-based architecture.
  • Health checks are monitored using Connect servers.
  • No backups are necessary.

Signaling and Media

Full SIP signaling and RTP with built-in firewall. All Signaling and Media servers work in Active/Active mode for redundancy.

  • Supports unlimited scalability simply by adding extra servers.
  • Multiple nodes can run side-by-side in active configuration. Linxa’s internal communication protocol allows Load Balancers to detect down
  • Signaling and Media servers and only distribute traffic to active ones.
    Signaling and Media servers can be turned off gracefully without losing any active calls (e.g., for maintenance).
  • Firewall is automatically provisioned in real-time using media IP and port data in SIP messages.
  • Heal Health checks are monitored using Connect servers.
  • No backups are necessary.

Routing Server

Sends call-by-call routing decisions to Linxa Signaling servers or any existing soft-switch using SIP 30X Multi-Contact Redirect.

  • Unlimited CAPS due to scalable architecture.
  • Response time of each request is under 0 milliseconds (can only be measured in nanoseconds)
  • Routing Servers are designed for 100% reliability. Multiple
  • Routing Servers work in active mode side-by-side. Each routing server can tolerate downtime of Database or Connect and continue to operate indefinitely with the last loaded routing data.
  • Have crash-guard mechanisms and built-in security checks even against possible software bugs. Version conflicts between various Linxa software and data structures do NOT effect Routing Servers.
  • Each routing server can be safely turned off without any service interruption.
  • Capable of connecting to ENUM, JSON, SIP INVITE complaint interfaces for any look-up platforms.
  • Built-in Number Portability functionality option so that no external lookup required.
  • Health checks are monitored using Connect servers.
  • No backups are necessary.
