Initially, NTU video was an open class of NTU, which was generally specially designed and downloaded. The speed is ok, but only two classes can be downloaded at the same time. Later, it was improved and relaxed to five or six.

Later, the server introduced YOUTUBE to support online viewing. But slowly, some open courses are not allowed to download. A typical example is Ou Li-chuan's Dream of Red Mansions. It is estimated that the popularity has increased greatly. Besides, the server load is also worrying. Mr. Ou also won an award in the field of open classes.

At present, the domestic open class videos can't be opened on the Internet, and those that can be downloaded can't be downloaded. It must be a network problem. The reason is that there is something wrong with the load balance of NTU server, or the access permission is set (what is the reason or the pressure is unknown). The landlord said that it has been blocked, which is unfounded, otherwise the network page could not be seen. Because the IP of the video and web server comes from the administrative building of Taiwan Province Provincial University, thank you.
