TECHNICAL FIELD The present invention relates to the field of communications technologies, and in particular, to a network service data flow control method, apparatus, and system. BACKGROUND OF THE INVENTION With the rapid development of network technologies, network services have higher and higher requirements on the transmission quality of data streams. For example, network voice services and network video services have high requirements on bursts and jitters of data streams. . In the prior art, the network service data flow needs to be stored and forwarded through all levels of nodes in the network.

For example, the video service based on the ip network, the data stream sent from the video source end is stored and forwarded by the nodes along the path, and the burst and jitter indicators are reduced, which exceeds the buffer processing capability of the receiving end, resulting in packet loss, mosaic, etc. Quality issues. In addition, after the IP network-based voice service or the TDM (Time Division Multiplexed) service data stream is forwarded through the network intermediate node, the bursts and jitters of the service data stream are also reduced, thereby affecting the call quality.

It does not necessarily ensure that sufficient bandwidth is allocated for important network services, so that the quality of service of important network services cannot be guaranteed, and it may also be Important network services allocate too much bandwidth, resulting in wasted bandwidth.
