Description Continually increasing demands for high-quality videoconferencing have brought a problem of fully automated environment setup. A media streams planning problem forms an important part of this issue. As the multimedia streams are extremely bandwidth-demanding, their transmission has to be planned with respect to available capacities of network links and the plan also needs to be optimal in terms of data transfer latencies. This paper presents an integer programming solution of the problem and its implementation. The implementation achieved very promising results in performance evaluating measurements. Compared to previous constraint-based solver, it is capable of finding optimal solution significantly faster, allowing for real-time planning of larger problem instances.
