Framework for secure audio streaming to wireless access network

Advances in the Internet and multimedia technologies have spurred many research efforts in Internet-based multimedia access systems, which integrate wireline and wireless networks. Internet-based multimedia streaming services are in need of a service creation model. In this paper, we presented such a model and framework for delivering real-time traffics to a wireless access network over public Internet Protocol (IP) backbone network. We have presented an experimental study of audio streaming when IP tunneling network using Generic Route Encapsulation (GRE) along with Internet Protocol Security (IPSec) is implemented. The impact on performance, with particular attention to Quality of Service (QoS) has been evaluated through a series of experiments. A compression scheme based on compressed real-time transport protocol (CRTP) used for delivering real-time traffic securely in wireless access network and preliminary performance results have been presented.
