Problems solved by technology

[0005] The present invention aims at the existence of data flow transmission purely pursuing the shortest path in the routing control of the prior art, which leads to the collection of traffic to some links, which is easy to cause network congestion problems, and the slow start and sudden braking of the sending rate in the TCP protocol on the transmission protocol. The transmission rate of the terminal is different and changes dynamically, which can easily cause a surge congestion problem similar to "ghost traffic jam". A traffic balancing method and device for downlink node information perception is proposed

Embodiment 1

[0031] Embodiment 1, combining Figure 1-Figure 4 , a downlink node information-aware traffic balancing method, such as figure 1 As shown, first, a brief introduction to the following process of the method is given:

[0032] Step 1. Collection of downstream node flow information: exchange flow information with downstream nodes in the form of detection packet interaction, count the flow information of the downstream nodes, perform characteristic statistics on the obtained flow information, and obtain the flow information feature vectors of each node;

[0033] Step 2. Update the traffic information characteristics of this node: query the flow information management database, and calculate the traffic information feature vector of this node based on the traffic characteristic information and adjustment threshold of the downlink node and its own node;

[0034] Step 3. Traffic adjustment: Pre-adjust the traffic according to the traffic information feature vector of this node, slow...

Description

technical field [0001] The invention belongs to the technical field of computer networks, and in particular relates to a flow balancing method and device for downlink node information perception. Background technique [0002] The design defects of the two core technologies of routing control and transmission protocols in the current network are important contributors to network congestion. In terms of routing control, data stream transmission simply pursues the shortest path, which causes traffic to converge on some links, which can easily cause network congestion. In the transmission protocol, take TCP as an example. The slow start and sudden stop of the transmission rate in the TCP protocol make the transmission rate of the terminal different and change dynamically, which can easily cause surge congestion similar to "ghost traffic jam". [0003] There is a phenomenon of swarm operation in the biological world, for example: (1) Sardine swarm movement phenomenon, individual...
