Scenario

The SBC performs complex route selection across multiple carrier networks.

Background Information

  • System is installed in a service-provider's network interconnecting two of its customers.
  • The User Equipment is pre configured with a DNS server which can return multiple SBCs to contact.
  • The SBC has sufficient routing intelligence to determine which carrier (A or B) hosts the subscriber.
  • Costs and performance/quality for routing may be predetermined preferences or vary based on a range of factors, including TOD/DOW, current load etc.
  • The requirements specified in the section "Background Information and Dependencies" of Minimal Out-Of-The-Box Configuration are met.
  • Ports and IP Interface Groups have been configured as described in NNI: Complex route selection
