Analysis for load-balancing techniques in intelligent network systems

The main idea behind the intelligent networks (IN) concept is to place the intelligence/service logic in the dedicated server and to meet various service requirements of subscribers and the development of new services in time. The (N + 1)-type architecture of the IN service system consists of front-end processors (FEP) and back-end processors (BEP), which are currently in service by a telecommunications company in Korea. The main characteristic of this architecture is a separation between the data plane and control plane of the network, such that the load-balancing table is used to distribute the traffic load among the processors, FEP and BEP, taking into account services. Since the values used in the load-balancing table affect the IN system performance significantly, this paper simulates the IN system and evaluates system performance depending on the values used in the table.
