Lifeline support of the Internet

Internet use has expanded in both social and corporate activity and is becoming indispensable to people´s lives as it gains in importance and popularity. Consequently, the demand for using the Internet as a communication lifeline is increasing. In lifeline support, emergency and/or important communication is the top priority. By transferring completely emergency and important communication from existing media to the Internet, convenient services in an advanced multimedia environment can be offered. However, standardization organizations such as IETF and ITU-T focus on emergency and important communication using VoIP or cooperation with the traditional telephone network with little consideration given to applications other than VoIP. For lifeline support of the Internet, this project aims to present middleware technology used as the basis for various emergency and important communications, and network technology for securing the quality of emergency and important communication. This paper demonstrates why such technology is needed, the framework for solving problems, and directivity of future research, etc.
