STREAMING
CDN acceleration service of stream media VOD means that the large amount of stream media content on the source website is transmitted to Dnion special storage device, which then distributes it to the stream media access servers in various locations, which are mainly located in the network nodes of the main operational company in each city. Request to the website from terminal user is re-directed to the media services node of the best response effect, through which, the terminal user is provided with the reliable stream media VOD service. See (Fig. -3)
Websites that provide VOD service of audio and video stream media, remote education, training and VOD service of media category etc.
Most stream media websites adopt centralized service, that is, all servers are collectively entrusted in one data centre, where centralized service and management are executed to all users. Online VOD service will increase loading on the server and consume tremendous bandwidth resource, meanwhile, it has very high requirement to the whole network transmission joint. In the current domestic network environment, fast increase of access quantity brings enormous pressure to the stream media server and the website bandwidth; in fact it is very difficult for ICP to provide VOD service to the online user all over the country.
With Dnion CDN acceleration service of stream media VOD, large amount of stream media content on the source website is transmitted to Dnion special storage device, which greatly reduced the server loading that is brought by the VOD service from the source website and spared the bandwidth resource, as well as effectively shunning off each of the congestion nodes on the network, resulting in high-quality, high efficiency stream media VOD service for the user.
1) High-flow media cache technology effectively solved the problem of blocking and inconsistency of online playback of stream media
2) The system supports many media format, including Windows Media, Real Media, Apple QuickTime and so on
3) There are sufficient storage space and outbound bandwidth, enabling the user to enjoy satisfactory experience.
CDN acceleration service of stream media live broadcast means that the stream media on the source website is transmitted to Dnion network through favorable link, where the stream is distributed layer after layer; each distribution goes on the favorable link before it reaches the edge stream media nodes; where stable and reliable live broadcast service is provided to the terminal user, refer to Fig.-4
Websites that provide live broadcast of audio and video stream media, e.g. media website of live news broadcast; websites of online television or sound broadcast; website of live broadcast of important sports and games.
Live broadcast is a new method of information dissemination ， immediacy and fastness makes it become one of the hottest network applications. The benefit of live broadcast is that it can bring about large amount of user access, which eventually brings considerable income in this eyeball competition age. Although it carries with great business opportunity, live broadcast is deemed to cause excessive concentrated access in certain period, therefore, it exerts very high requirement on the network and server; but the attribute of existing network structure with the widely-dispersed operational company limits its growing paces.
Dnion CDN acceleration of stream media live broadcast can provide stable web live broadcast service to the terminal user all over the country through the optimized distribution via the CDN network nodes; and the request to the website from the terminal user is re-directed to the nearest media service nodes of the best response, thus no matter where the user comes from, he can likely obtain high-quality stream media content from the optimal stream media server, meanwhile, the website need not to worry about the bandwidth pressure due to access by large amount of users.
1) Cut off operating cost for the customer, it needn’t to invest much to construct high-level system and network environment; service is provided depending on the live broadcast event, so the customer can efficiently enjoy the benefit of extensibility via VDN
2) Distribution by layer guarantees the transmission quality of live broadcast, minimizing the affect from the transmission joint to the live broadcast effect.
