Optimization of Core Network Router for Telecommunication Exchange

Abstract

The operation of Core Router is to restrict Network Broadcast to the LAN, to act as default gateway, to move data between different networks and to advertise loop free Path. The technology of Wifi, WiMAX (Worldwide Interoperability for Microwave Access), GPRS (General Packet Radio Services), EDGE (Enhanced Data Rates For GSM Evolution), EV-DO (Evolution Data Optimized) which are used for remote data access. A Router must be able to support multiple telecommunications interfaces of the highest speed in use in the core Internet and must be able to forward IP packets at full speed on all of them. It must also support the routing protocols being used in the core. In telephone system, Core Routers installed on the network are used as carriers to carry data from traffic sources to sinks. The optimization formulation based on Telecommunication network to obtain an optimal decision for the Core Router on whether to accept packets from a traffic source. This decision is made to maximize the reward of data delivery while the quality-of-service performance is guaranteed. From the performance evaluation, a Core Router with network optimization can achieve the highest reward while the maximum packet-blocking probability requirements met. The Core Router is a cell-site access platform specifically designed to optimize, aggregate and transport mixed-generation Radio Access Network (RAN) traffic. It is used at a cell site as part of an IP-RAN or Cell Site DCN solution. An IP RAN solution in which the Core Router extends IP connectivity to the cell site and Base Transceiver Station (BTS), through a Fast Ethernet interface to the BTS, the router provides bandwidth-efficient IP transport of voice and data bearer traffic, as well as maintenance, control and signaling traffic over the IP using traditional circuits.
