            Abstract : 
We evaluate the impact of network, and protocol heterogeneity on real-time application performance. We focus on TCP and UDP supportive role, also in the context of network stability and fairness. We reach several conclusions on the specific impact of wireless links, MPEG traffic friendliness, and TCP version efficiency. Beyond that, we also reach an unexpected result: UDP traffic is occasionally worse than TCP traffic when the right performance metric is used.
