SD-WAN, Chinese called wide-area software-defined network, is a service formed by applying SDN technology to the WAN scene, and is also a brand-new network innovation architecture.
This service is used to connect a wide range of enterprise networks, data centers, Internet applications, and cloud services, simplifying IT management and operations, reducing WAN expenses, and increasing network connectivity flexibility.
One of the biggest advantages of SD-WAN is that it solves the problem of Internet instability and can greatly satisfy the requirements of application immediacy and real-time.
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.
