NETWORK ARCHITECTURE FOR ROUTING OF ADJUNCT BASED SERVICES

摘要

The present invention is a novel architecture design for adjunct based archi tectures. The architecture is built on two key principles; routing traffic based on geogra phic origin and routing based on customer group. In order to implement the geographic routing, the c ommunications network is split into regions. A method used to achieve optimal regions is d escribed. Further realization of the geographic routing entails a design of the architecture r egions, determining the number of adjuncts/region and equally distributing the loads across the adju nct sites. Also, described is the method for optimally homing traffic between the OAS and TAS A and between TAS A and TAS B. The architecture eliminates deficiencies in prior art architect ures such as intertoll focusing, architecture instability and reliability.
