摘要： A routing mechanism, service or system operable in a distributed networking environment. One preferred environment is a content delivery network (CDN) wherein the present invention provides improved connectivity back to an origin server, especially for HTTP traffic. In a CDN, edge servers are typically organized into regions, with each region comprising a set of content servers that preferably operate in a peer-to-peer manner and share data across a common backbone such as a local area network (LAN). The inventive routing technique enables an edge server operating within a given CDN region to retrieve content (cacheable, non-cacheable and the like) from an origin server more efficiently by selectively routing through the CDN's own nodes, thereby avoiding network congestion and hot spots. The invention enables an edge server to fetch content from an origin server through an intermediate CDN server or, more generally, enables an edge server within a given first region to fetch content from the origin server through an intermediate CDN region.

The invention enables an edge server to fetch content from an origin server through an intermediate CDN server or, more generally, enables an edge server within a given first region to fetch content from the origin server through an intermediate CDN region. As used herein, this routing through an intermediate server, node or region is sometimes referred to as “tunneling.”
摘要翻译：在分布式网络环境中可操作的路由机制，业务或系统。一个优选的环境是内容传送网络（CDN），其中本发明提供了到原始服务器的改进的连接，特别是对于HTTP流量。在CDN中，边缘服务器通常被组织成区域，每个区域包括一组内容服务器，其优选地以点对点的方式操作，并且通过诸如局域网（LAN）的公共骨干网共享数据。本发明的路由技术使得在给定CDN区域内的边缘服务器能够通过选择性地路由通过CDN自己的节点更有效地从原始服务器检索内容（可高速缓存，不可缓存等），从而避免网络拥塞和热点。本发明使得边缘服务器能够通过中间CDN服务器从原始服务器获取内容，或者更一般地，允许给定第一区域内的边缘服务器通过中间CDN区域从原始服务器获取内容。如本文所使用的，通过中间服务器，节点或区域的该路由有时被称为“隧道”。
