Abstract: By defining data transmission priority the real-time flow transmission performance can be improved when both the real-time and the non-real-time flow data use the same data channel to transmit concurrently. When the non-real-time control information varies greatly in a short time, due to the high priority non-real-time data or packet loss probability increase, the real-
time flow data with fixed stream is also affected greatly. A new method of mixed data transmission is proposed through the study on bandwidth estimation, packet loss probability, and the occasion transmission data increase greatly in different priority queues in a short time. The experimental results show that the proposed method is adaptive, and presents good performance for both bandwidth utilization and real-time flow transmission effect.
