It is a network of servers distributed throughout the world for providing high-speed, reliable content transmission and distribution services. CDNs increase web page loading speed, reduce network latency, and relieve the load pressure of the origin server by storing content on the server closest to the user and transmitting content using a proximity routing technique. The working principle of the CDN is that after a user issues a request, the CDN automatically selects a server closest to the user to respond to the request, instead of directly accessing the original origin server. Therefore, the time and network delay of data transmission can be reduced, and the access speed and experience of a user can be improved.

In the embodiment, firstly, based on the resource data obtained from the CDN server, when the resource data corresponding to the request resource information does not exist in the CDN server caching process, the resource data is obtained from the OSS cloud platform, so that the data responsiveness is improved, the accelerated downloading of the short video is realized, and the user experience is improved.
In this embodiment, the SDK includes API (Application Programming Interface) means for providing a series of interfaces and functions for a developer to interact with an operating system, platform or third party service, means such as a compiler, debugger, integrated Development Environment (IDE), etc. for writing, compiling, debugging and deploying code. The OSS cloud platform is used for transcoding short video information through on-demand service, performing video processing on a transcoding result, and storing target video after video processing, wherein the target video is permanently stored. And integrating a player SDK at the playing end of the second client, wherein the player SDK requests resources from a CDN server (content distribution network), and the CDN server sends cached data to the client if the CDN server has a cache. If the CDN server caches no data, the data is pulled in the OSS, returned to the second client, and cached on the CDN.
The beneficial effects of the technical scheme are that: the method provides SDK with complete functions, a stable and simple interface for enterprise users, supports one-stop service of video acquisition, composite uploading, transcoding watermarking, content distribution and video storage, helps enterprises to quickly realize self-contained APP access short video functions or online independent short video APP, improves the comprehensiveness of the short video functions, provides one-stop short video shooting, editing, compositing, uploading and other functions, supports second-level starting pictures, enjoys extremely smooth audiovisual feast, shortens the waiting time of users and improves user experience.

9. The short video acceleration system of the OSS cloud cluster of claim 8, wherein the optimization module is further configured to detect a network quality level, identify a current policy of a data transmission state in a TCP protocol stack when the network quality level is determined to be less than a preset level threshold, and perform adjustment of a more aggressive policy.
10. The short video acceleration method of the OSS cloud cluster is characterized by comprising the following steps of:
the method comprises the steps that a first client generates short video information and uploads the short video information to an OSS cloud platform;
the OSS cloud platform carries out transcoding processing on the short video information through the on-demand service, carries out video processing on a transcoding processing result, and stores target video after video processing;
the second client requests resources from the CDN server;
the CDN server receives the request resource information sent by the second client and judges whether resource data corresponding to the request resource information exists in the caching process or not; when the resource data corresponding to the request resource information exists in the caching process, the resource data is fed back to the second client; when it is determined that the resource data corresponding to the request resource information does not exist in the caching process, pulling information is generated and sent to the OSS cloud platform, the resource data returned by the OSS cloud platform is received, and the resource data is fed back to the second client.
