BorderNet Session Border Controller (SBC) Efficient Use of Virtualized Resources

The BorderNet SBC cloud-native architecture efficiently and effectively leverages today’s powerful multi-core compute platforms in a way that automatically enables superior network infrastructure resource utilization.

  • Reduce total cost of ownership (TCO) of vSBC (virtualized session border controller) infrastructure with a dynamic compute resource allocation model.
  • Dynamically distribute processor loads across all platform vCPUs while simultaneously protecting each vCPU from overload.
  • High performance without the typical manual, tedious, and recurring engineering costs associated with pre-allocating vCPUs to handle specific processing loads.
  • Idle and underutilized computing resources minimized.
