Dynamic routing in the multiple carrier international network

Presents an overview of the efforts of the 13 participating carriers that comprise the Worldwide Intelligent Network (WIN) Dynamic Routing Group to introduce dynamic routing internationally. The authors propose that the introduction of dynamic routing could be accomplished in stages, starting with the deployment of flexible overflow routing for bilateral networks. Then the authors examine performance feasibility issues associated with multiple carrier transit routing and analyze data items that need to be exchanged by international carriers to realize dynamic traffic control. They also review major conclusions that can be made based on the results of the first WIN dynamic routing trials. Finally, they review a proposal for standardization of certain signaling messages that enables the realization of real-time state-dependent routing in a multiple carrier environment.<
