Circuit switched and packet switched networks are two different network technologies that have seen wide spread deployment world wide in the past. Circuit switched networks are designed for delay sensitive traffic. While packet switched networks offer bandwidth efficiency. Today, with bandwidth being a scarce resource which significantly influences the communication cost, efforts are increasing to develop delay-sensitive transport mechanisms over packet switched networks. One of the central requirements of WIN-T system is to provide bandwidth efficient simultaneous voice, data and video services and Command and Control (C2) on the move (C2OTM) at all levels of security. In this proposal, we present the framework for the design of an innovative gateway architecture to bridge circuit switched and packet switched networks, that significantly reduce the media processing time. This design is based on a detailed analyses of the requirements for the transport of delay-sensitive traffic between circuit switched and packet switched networks. BENEFITS: The most significant effect of this technology is that it offers the ability to integrate voice and data network to greatly reduce the tariff rates of voice calls. Some analysts expect the overall growth of packetized voice market at 149% annually through 2001 to about $1.89 billion. This research will benefit the telecommunication industry and every major corporate sector which leases communication lines like T1 and T3 for inter-office voice communication.
