Core session routing

Leveraging IP backbones, core session routing alleviates challenges associated with scaling and managing routing with a highly distributed architecture. Decoupling routing from applications and centralizing routing information provides mobile service providers with a streamlined architecture that routes all SIP sessions to-and-from all IP and TDM access and interconnect borders. Core session routing also provides superior scalability when routing demands dynamic, real-time decisions for each session for multiple sources and destinations.

The Open Session Routing (OSR) architecture features the Net-Net Session Router session routing proxy (SRP) and a world-class ecosystem of routing database products and services from Acme Packet partners. Using industry-standards—ENUM, SIP, XML or DNS—for routing queries, the OSR architecture results in extremely fast session routing performance and increased network capacity. The powerful combination of the Acme Packet SRP and partner ecosystem provides lower overall network costs compared to legacy architectures in which the routing function is distributed among several SIP elements.


The Acme Packet edge

Provisioning routing information and control in SIP elements is extremely expensive and error-prone, and the Net-Net Session Router centralizes and consolidates routing control, reducing costs and allowing mobile service providers to benefit from:

  • High-performance session routing proxy in cost-effective platforms
  • Dynamic and comprehensive routing control
  • Flexible routing database options—on-board, ecosystem products and services
  • Open and standards-based solutions
  • Simplified route provisioning
