摘要： A content delivery network (CDN) typically includes a mapping system for directing requests to CDN servers. One or more peer machines become associated with the CDN, and the CDN mapping system is then used to enable a given peer to locate another peer in the P2P network, and/or a CDN server. Using this hybrid approach, CDN customer content may be delivered from the CDN edge network, from the P2P network, or from both networks. In one embodiment, customer content is uploaded to the CDN and stored in the edge network, or in a storage network associated therewith. The CDN edge network is then used to prime the P2P network, which may be used to take over some of the content delivery requirements for the customer content. The decision of whether to use edge network or peer network resources for delivery may be based on load and traffic conditions.

摘要： A method and system of load balancing application server resources operating in a distributed set of servers is described. In a representative embodiment, the set of servers comprise a region of a content delivery network. Each server in the set typically includes a server manager process, and an application server on which edge-enabled applications or application components are executed. As service requests are directed to servers in the region, the application servers manage the requests in a load-balanced manner, and without any requirement that a particular application server spawned on-demand.

摘要： Business applications running on a content delivery network (CDN) having a distributed application framework can create, access and modify state for each client. Over time, a single client may desire to access a given application on different CDN edge servers within the same region and even across different regions. Each time, the application may need to access the latest “state” of the client even if the state was last modified by an application on a different server. A difficulty arises when a process or a machine that last modified the state dies or is temporarily or permanently unavailable. The present invention provides techniques for migrating session state data across CDN servers in a manner transparent to the user. A distributed application thus can access a latest “state” of a client even if the state was last modified by an application instance executing on a different CDN server, including a nearby (in-region) or a remote (out-of-region) server.

摘要： Content is dynamically assembled at the edge of the Internet, preferably on content delivery network (CDN) edge servers. A content provider leverages an “edge side include” (ESI) markup language that is used to define Web page fragments for dynamic assembly at the edge. Dynamic assembly improves site performance by caching objects that comprise dynamically-generated pages at the edge of the Internet, close to the end user. Instead of being assembled by an application/web server in a centralized data center, the application/web server sends a page template and content fragments to a CDN edge server where the page is assembled. Each content fragment can have its own cacheability profile to manage the “freshness” of the content. Once a user requests a page, the edge server examines its cache for the included fragments and assembles the page on-the-fly.
摘要翻译： 内容在互联网的边缘动态组合，最好在内容传送网络（CDN）边缘服务器上。 内容提供商利用“边缘包含”（ESI）标记语言，用于定义边缘动态组合的网页片段。 动态组合通过缓存在Internet边缘动态生成的页面的对象，靠近最终用户来提高站点性能。 应用程序/ Web服务器不是由集中式数据中心中的应用程序/ Web服务器组装，而是将页面模板和内容片段发送到组合页面的CDN边缘服务器。 每个内容片段可以具有其自己的可缓存性配置文件来管理内容的“新鲜度”。 一旦用户请求页面，边缘服务器检查其包含的片段的高速缓存，并即时组合该页面。
