The server carries the number of concurrent analysis (how much concurrent support is supported by the 100M bandwidth server)

How many concurrent problems the single server supports in the streaming media on demand system, from the perspective of the P2P application, there is no fixed number, specifically with the number of users and the server The number of files is related. The number of movies on a server is inversely proportional to the user concentration. The fewer the number of movies, the higher the concentration, the better the P2P effect. Conversely, the more files there are, the harder it is for users connected to this server to concentrate, and the more difficult it is to transfer data to each other via P2P.

There are generally three cases:

A. Less user groups

In this case, the general user source has very little precipitation, and the bandwidth is mostly provided by the server. 100M bandwidth The server can also support a minimum of 300 people to order 400K code rate movies online. The conclusion is that the website can meet the demand for on-demand. Support for concurrent numbers: 300 or more (provided that 300 people watch different movies).

B. Users are very much

At this time, many movie files are quickly released, so the server does not need to provide bandwidth, so the server can use the bandwidth. With fewer files, it can support more users. In conclusion, the server can meet the demand and support the number of concurrent: unlimited.

C. The number of users is generally large (between A and B)

This situation is the most interesting, because the number of sources of most files does not reach the bandwidth that does not require the server to provide bandwidth. At the same time, users have more on-demand, so there are too many different files on the server. Therefore, many files require the bandwidth provided by the server. The user does not have too many sources, and the bandwidth provided by the server is limited. When the user orders some movies, it may be Will be a bit of a card.

The solution to the problem caused by the third situation is: do not put too many movies on a server, and strive to improve the user's concentration. As for the number of specific movies, it is better to have a fixed amount of data. As long as it is kept at a suitable amount, the webmaster can dynamically adjust this number as the website develops. Support concurrent number: 300 & mdash; unlimited.

In summary, if the webmaster wants a server to achieve good service results and allows on-demand users to watch online, we recommend that the number of movies on a server should not exceed 2000. The server can first upload 500G content, and when the number of users is enough, it can put 1T content (one server can be configured with 3 hard disks, and a single 300G or 500G).

For the big station, because the new movie just released has no user source, the users of the previous on-demand mainly collect data from the server, and the pressure on the main server is relatively large, so it is better to add one station to the station. The dedicated server provides bandwidth support for newly released movies, which makes it easier to form a scale effect. The source can be quickly precipitated. After the user provides bandwidth for the user, the newly released movie file is moved from the dedicated server to the main server. It does not affect the normal service provided by the main server.
