Patent number: 8477630Abstract: A routing mechanism operable in a distributed networking environment, such as a content delivery network (CDN), provides improved connectivity back to an origin server, especially for HTTP traffic. The technique enables an edge server operating within a given edge region to retrieve content (cacheable, non-cacheable and the like) from an origin server more efficiently by selectively routing through the network's own nodes, thereby avoiding network congestion and hot spots. The technique enables an edge server to fetch content from an origin server through an intermediate edge server or, more generally, enables an edge server within a given first region to fetch content from the origin server through an intermediate edge region.Type: GrantFiled: June 4, 2012Date of Patent: July 2, 2013Assignee: Akamai Technologies, Inc.Inventors: Claudson F. Bornstein, Timothy K. Canfield, Gary L. Miller, Satish B. Rao, Ravi Sundaram

Patent number: 8194538Abstract: 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.Type: GrantFiled: April 18, 2011Date of Patent: June 5, 2012Assignee: Akamai Technologies, Inc.Inventors: Claudson F.
