The method for self-oscillation area evalution and critical (stationary) point selection is introduced. The patametric and phase portraits for systems with algorithms RED, GRED, DSRED and ARED are analyzed.</abstract><trans-abstract xml:lang="ru">В статье построена математическая модель процесса передачи трафика c регулируемой алгоритмом типа Random Early Detection (RED) динамической интенсивностью потока. Предложен метод определения области значений параметров RED, при которых возникают автоколебания динамических переменных модели.
