specific Embodiment approach 1
[0032] Specific implementation mode 1: A closed-loop congestion control method based on cross-layer buffer memory management in a broadband multimedia satellite system is completed by the following steps:
[0033] Step 1. In a broadcasting time interval, the terminal or ground station sends out ATM cell stream to the satellite channel, the ATM cell stream is transmitted to the satellite via the satellite channel uplink, and the ATM cell stream is front-end via the satellite After processing and exchange, it is divided into four types of priority data streams, and the four types of priority data streams are respectively stored in the corresponding four types of buffer memory;
