G06F 1760

US Classification:

705 1, 709223, 709224, 709235, 713213

Abstract:

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.

Abstract:

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 that determines a customer web server from the plurality of customer web servers, sending the web page that includes static content represented by an embedded URL from the customer web server, sending a second request from the web client for resolving the URL to the client DNS server sending the second request from the client DNS server to the POP DNS server that determines a web cache from the plurality of web caches, sending the static content from the web cache to the web client, and outputting the static content with the web client.

International Classification:

US Classification:

709217, 370229, 718105

Abstract:

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.

International Classification:

US Classification:

709225, 709219, 709226, 709227

Abstract:

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 servers 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 servers address to return to the requestor. The DNS server sends any responses to forwarded requests to the client DNS server. When more than one DNS server is authoritative for an overlapping DNS group, the invention ensures that the persistence and latency tables are synchronized with any other DNS servers.

Abstract:

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.

Abstract:

A load balancing service for a plurality of customers performs load balancing among a plurality of customer Web servers. Requests for Web content are load balanced across the customer Web servers. The load balancing service provider charges a fee to the customers for the load balancing service. A caching service is also provided that comprises a plurality of caching servers connected to a network. The caching servers host customer content that can be cached and stored, e. g. , images, video, text, and/or software. The caching servers respond to requests for Web content from clients. The load balancing service provider charges a fee to the customers for the Web caching service.

US Classification:

709203, 709245, 709229

Abstract:

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.
