Patent number: 9026661Abstract: A method for determining metrics of a content delivery and global traffic management network provides service metric probes that determine the service availability and metric measurements of types of services provided by a content delivery machine. Latency probes are also provided for determining the latency of various servers within a network. Service metric probes consult a configuration file containing each DNS name in its area and the set of services. Each server in the network has a metric test associated with each service supported by the server which the service metric probes periodically performs metric tests on and records the metric test results which are periodically sent to all of the DNS servers in the network. DNS servers use the test result updates to determine the best server to return for a given DNS name. The latency probe calculates the latency from its location to a client's location using the round trip time for sending a packet to the client to obtain the latency value for that client.Type: GrantFiled: February 7, 2014Date of Patent: May 5, 2015Assignee: Akamai Technologies, Inc.Inventors: Eric Sven-Johan Swildens, Richard David Day, Ajit K.

Patent number: 8195831Abstract: Methods for determining and utilizing server performance metrics in a network are provided. For example, such methods can involve determining the service availability and metric measurements of types of services provided by a content delivery machine. User weightings can be used to indicate whether more traffic should be sent to one content server address compared to another. DNS servers use the test result updates and/or user weightings to determine the best server to return in response to a request to resolve a given DNS name. Computer systems and apparatus for carrying out such methods are also provided.Type: GrantFiled: January 6, 2011Date of Patent: June 5, 2012Assignee: Akamai Technologies Inc.Inventors: Eric Sven-Johan Swildens, Richard David Day, Ajit K.

Patent number: 7979580Abstract: A content delivery and global traffic management network system provides a plurality of caching servers connected to a network. The caching servers host customer content that can be cached and stored, and respond to requests for Web content from clients. If the requested content does not exist in memory or on disk, it generates a request to an origin site to obtain the content. A DNS Server load balances network requests among customer Web servers and directs client requests for hosted customer content to the appropriate caching server. The customer pays a service that provides the content delivery and global traffic management network system a fee for usage of the content delivery and global traffic management network system.Type: GrantFiled: January 26, 2009Date of Patent: July 12, 2011Assignee: Akamai Technologies, Inc.Inventors: Eric Sven-Johan Swildens, Richard David Day, Ajit K.
