Patent number: 7484002Abstract: 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: March 16, 2007Date of Patent: January 27, 2009Assignee: Akamai Technologies, Inc.Inventors: Eric Sven-Johan Swildens, Richard David Day, Ajit K.

Patent number: 7225254Abstract: A method for a computer network includes sending a first request from a web client for resolving a first web address of a web page to a client DNS server, sending the first request from the client DNS server to a POP DNS server within a POP server network, using a probe server in the POP server network to determine traffic loads of a plurality of customer web servers, each of the customer web servers storing the web page, using the POP DNS server to determine a customer web server from the plurality of customer web servers, the customer web server having a traffic load lower than traffic loads of other customer web servers in the plurality of customer web servers, requesting the web page from the customer web server, the web page including static content represented by an embedded URL, sending the web page from the customer web server to the web client, sending a second request from the web client for resolving the URL to the client DNS server.Type: GrantFiled: February 6, 2004Date of Patent: May 29, 2007Assignee: Akamai Technologies, Inc.Inventors: Eric Sven-Johan Swildens, Ajit K.

Patent number: 7194522Abstract: 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 (SPD) load balances network requests among customer Web servers and directs client requests for hosted customer content to the appropriate caching server which is selected by choosing the caching server that is closest to the user, is available, and is the least loaded. SPD also supports persistence and returns the same IP addresses, for a given client. The entire Internet address space is broken up into multiple zones. Each zone is assigned to a group of SPD servers.Type: GrantFiled: June 21, 2004Date of Patent: March 20, 2007Assignee: Akamai Technologies, Inc.Inventors: Eric Sven-Johan Swildens, Richard David Day, Ajit K.

Patent number: 7185052Abstract: A meta content delivery network system provides a Meta CDN DNS (MCD) server that performs scheduling for multiple content delivery networks (CDN) and is authoritative for all domains given to the CI)Ns. The MCD contains information about CDNs which participate in each CDN domain names. Each CDN provides to the Meta CDN a domain name that will refer to their CDN's portion of the entire Meta CDN for that Meta CDN customer. The MCD receives domain name query requests from local DNSs and selects the proper CDN address based on a predefined capacity reservation of CDNs and statically mapped preferences for certain clients and directs the local DNS requests to the proper CDN address.Type: GrantFiled: May 16, 2001Date of Patent: February 27, 2007Assignee: Akamai Technologies, Inc.Inventor: Richard David Day

Patent number: 7032010Abstract: A scalable domain name system with persistence and load balancing receives requests from client DNS servers or other DNS servers. Each DNS server is associated with a subset of the DNS groups in the network and the invention checks to see if the client DNS server is part of the DNS group that the DNS server is authoritative. If the DNS server is not authoritative for the client DNS server's group, then the request is forwarded to the proper DNS server. The receiving DNS checks to see if a persistent response is required for the request. If a persistent response is required, the appropriate IP address is returned to the requestor. If a persistent response is not required, the load, availability, and latency of the content servers are used to determine the proper content server's address to return to the requestor.Type: GrantFiled: June 21, 2004Date of Patent: April 18, 2006Assignee: Speedera Networks, Inc.Inventors: Eric Sven-Johan Swildens, Richard David Day, Vikas Garg

Each DNS server is associated with a subset of the DNS groups in the network and the invention checks to see if the client DNS server is part of the DNS group that the DNS server is authoritative. If the DNS server is not authoritative for the client DNS server's group, then the request is forwarded to the proper DNS server. Otherwise, the invention checks a persistence table to see if a persistent response is required for the request. If a persistent response is required, the appropriate IP address entry in the table is returned to the requestor. If a persistent response is not required, the invention determines the load, availability, and latency of the content servers from information stored in a latency table to determine the proper content server's address to return to the requestor. The DNS server sends any responses to forwarded requests to the client DNS server.Type: GrantFiled: August 11, 2000Date of Patent: June 22, 2004Assignee: Speedera Networks, Inc.Inventors: Eric Sven-Johan Swildens, Richard David Day, Vikas Garg

Publication number: 20030065763Abstract: 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: ApplicationFiled: July 19, 2001Publication date: April 3, 2003Inventors: Eric Sven-Johan Swildens, Richard David Day, Ajit K.

Patent number: 6484143Abstract: A user interface device and system for providing a shared GTM and CDN (collectively Universal Distribution Network) for a service fee, where the customer or user does not need to purchase significant hardware and/or software features. The present interface device and system allows a customer to scale up its Web site, without a need for expensive and difficult to use hardware and/or software. In a preferred embodiment, the customer merely pays for a service fee, which can be fixed, variable, lump some, or based upon a subscription model using the present system. The present device and system are preferably implemented on a system including a novel combination of global traffic management and content distribution.Type: GrantFiled: August 18, 2000Date of Patent: November 19, 2002Assignee: Speedera Networks, Inc.Inventors: Eric Sven-Johan Swildens, Richard David Day, Ajit K.
