Demand-based edge caching video content system and method
Abstract:
A method (300) and system (200) for of conserving resources in a video-on-demand environment are provided. The method (300) includes storing a stub file (223) on an edge storage device while storing content (110) at a central storage device (222). When a video-on-demand request (440) is received, a resource management system (206) reads (305) the stub file (223) to determine a storage location at the central storage device (222). The resource management system (206) then retrieves the content (110) from the storage location determined from the stub file (223) and either stores it at an edge storage device (111) or delivers it the a subscriber device (109) to fulfill the video-on-demand request (440).
Abstract(Chinese):

提供了一种用于在视频点播环境中节省资源的方法（300）和系统（200）。 方法（300）包括在边缘存储设备上存储存根文件（223），同时在中央存储设备（222）上存储内容（110）。 当接收到视频点播请求（440）时，资源管理系统（206）读取（305）存根文件（223）以确定中央存储设备（222）处的存储位置。 资源管理系统（206）然后从从存根文件（223）确定的存储位置检索内容（110），并将其存储在边缘存储设备（111），或者将其提供给用户设备（109）以实现 视频点播请求（440）。
