Mobile code implementation of the RTP protocol in Java: design choices and evaluation

The use of a mobile code, partly interpreted language such as Java is investigated as a tool to build highly portable implementations of multimedia communication protocols. In particular, we concentrate on the implementation of the real-time protocol and focus our attention on three main issues: first, we evaluate the quality and accuracy of the services offered by some relevant primitive operations as they are provided on different Java platforms; second, we concentrate on a suitable object-oriented design which makes RTP functionalities both well-integrated and easily accessible; finally, we perform an overall evaluation of the efficiency of the proposed implementation both in terms of resulting packet loss and delay jitter.
