  • Patent number: 7552338
    Abstract: A dynamic multimedia fingerprinting system is provided. A user requests multimedia content from a Web cache server that verifies that the user is authorized to download the content. A custom fingerprint specific to the user is generated and dynamically inserted into the content as the content is delivered to the user. The custom fingerprint can be generated on the Web cache server or at the content provider's server. The system allows a content provider to specify where the custom fingerprint is inserted into the content or where the fingerprint is to replace a placeholder within the content.

  • Publication number: 20090132648
    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 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.

  • Patent number: 7523181
    Abstract: 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.

  • Publication number: 20090055552
    Abstract: A decrypting load balancing array system uses a Pentaflow approach to network traffic management that extends across an array of Decrypting Load Balancing Array (DLBA) servers sitting in front of back end Web servers. One of the DLBA servers acts as a scheduler for the array through which all incoming requests are routed. The scheduler routes and load balances the traffic to the other DLBA servers (including itself) in the array. Each DLBA server routes and load balances the incoming request packets to the appropriate back end Web servers. Responses to the requests from the back end Web servers are sent back to the DLBA server which forwards the response directly to the requesting client.

  • Publication number: 20090007241
    Abstract: A secure streaming content delivery system provides a plurality of content servers connected to a network that host customer content that can be cached and/or stored, e.g., images, video, text, and/or software. The content servers respond to requests for customer content from users. The invention load balances user requests for cached customer content to the appropriate content server. A user makes a request to a customer's server/authorization server for delivery of the customer's content. The authorization server checks if the user is authorized to view the requested content. If the user is authorized, then the authorization server generates a hash value using the authorization server's secret key, the current time, a time-to-live value, and any other information that the customer has configured, and embeds it into the URL which is passed to the user. A content server receives a URL request from the user for customer content cached on the content server.

  • Publication number: 20080281946
    Abstract: A method and apparatus for the automatic migration of data via a distributed computer network allows a customer to select content files that are to be transferred to a group of edge servers. Origin sites store all of a customer's available content files. An edge server maintains a dynamic number of popular files in its memory for the customer. The files are ranked from most popular to least popular and when a file has been requested from an edge server a sufficient number of times to become more popular than the lowest popular stored file, the file is obtained from an origin site. The edge servers are grouped into two service levels: regional and global. The customer is charged a higher fee to store its popular files on the global edge servers compared to a regional set of edge servers because of greater coverage.

  • Patent number: 7194522
    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.

  • Patent number: 7032010
    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 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.
