    Abstract: A video optimizer receives a request to optimize a source file and stream the optimized file. The request may be accompanied by a key uniquely identifying the original source file to be optimized and an optimized version of the source file to stream to the client. The key uniquely identifies the source video file as it exists on an origin server to prevent transmission of modified source video and the optimized version of the source file by optimization parameters to ensure compatibility with the user device. The video optimizer queries a cache database in response to the received request, which contains references keys and locations of optimized source files among local caches in a cluster of video optimizers. The cache database responds indicates whether a matching optimized version of the source file exists in a local cache of a given video optimizer in the cluster.

    Abstract translation: 视频优化器接收优化源文件并流优化文件的请求。 该请求可以伴随着唯一地标识待优化的原始源文件的密钥和源文件的优化版本流向客户端。 密钥唯一地标识原始服务器上存在的源视频文件，以防止通过优化参数传输修改的源视频和源文件的优化版本，以确保与用户设备的兼容性。 视频优化器响应于接收到的请求来查询缓存数据库，该请求包含优化的源文件在视频优化器的集群中的本地高速缓存之中的引用密钥和位置。 缓存数据库响应指示源文件的匹配优化版本是否存在于集群中给定视频优化器的本地缓存中。
