Internet live broadcast is an "upload-download" network environment. Because of the demand for real-time interconnection, the requirements for the uplink network are high. However, due to the wide distribution of live teachers, when the upstream data stream arrives at the video source station or passes through the server, delays and jams caused by packet loss may occur, and the stability of the live broadcast is affected. In addition, interactive live teaching also causes the source station or server to handle two video streams, including live teachers and students, and delays and out of sync. However, if the SD-WAN network is accessed, the system can determine the optimal path within the network according to the user's network condition and the final destination address of the access, and push this optimal path to the user.If we use our network environment as a traffic network, it is easy to understand the SD-WAN network. Everyone knows that there are more cars on the road, and there will be traffic jams and congestion. Building new roads or increasing bandwidth requires a high cost, and this can't be done for a while, and the cost is often unaffordable for ordinary users. However, the access to the SD-WAN network is equivalent to the definition of a bus lane through virtual software. The bus lane is only allowed to travel by bus during the specified time. That is to maximize the existing resources of the network, and maximize the use of existing resources. With the live class on Meng Meng, SD-WAN is equivalent to a dedicated connection channel between the teacher who lectures and the students who are attending the class, and can also accurately identify who is the "bus" that needs to use the dedicated channel. Let this channel be used exclusively by the users of the budding class during the live class. In the SD-WAN environment, even if the live teacher is mobile, it can provide a stable connection, so that teachers can guide learning anytime, anywhere. Switching between multiple classes, or between teachers and classmates, is also very convenient and has no stuck. Think about it, is this super smooth live class, will it be particularly cool?
