摘要： Under the present invention, the performance of a set of system resources is monitored in response to incoming request traffic. When a system resource is approaching an overload condition, a corrective action is identified and implemented. Overload thresholds for each system resource and appropriate corrective actions are contained within a management policy. Based on a performance history of the corrective actions, the management policy can be changed/revised.

摘要： CDNs and inexpensive and available local (client) storage are combined to increase the efficiency of content delivery and improve the user experience. A large-content element, such as a video file, is stored in segments on one or more servers, allowing clients to make simultaneous requests for segments of the content in parallel. A CDN responds to these requests, optimizing the use of the resources on the CDN nodes. The responses from the CDN are cached during an intermediate process and then delivered, in proper order, to the requesting client. By requesting segments of the content element from multiple locations in parallel rather than requesting a single file containing the entire content element, the burden on the CDN nodes is reduced. Further, since the segments are requested in parallel, cost-of-delivery issues can be factored into the delivery schedule more easily (e.g., bandwidth, time of delivery, whether data is cached), thereby making the delivery process smoother and more economical.

摘要翻译： CDN和廉价可用的本地（客户端）存储被组合以提高内容传送的效率并改善用户体验。 诸如视频文件的大内容元素被存储在一个或多个服务器上的段中，允许客户机并行地对段的内容进行同时请求。 CDN响应这些请求，优化CDN节点上资源的使用。 来自CDN的响应在中间过程中缓存，然后以适当的顺序发送给请求客户端。 通过并行地从多个位置请求片段的内容元素，而不是请求包含整个内容元素的单个文件，减少了CDN节点的负担。 此外，由于并行请求段，因此可以更容易地将交付成本问题（例如，带宽，传送时间，数据是否被缓存）等因素交付到传送计划中，从而使传送过程更平滑和更经济。
