| 20090210528 | METHOD FOR DETERMINING METRICS OF A CONTENT DELIVERY AND GLOBAL TRAFFIC MANAGEMENT NETWORK - 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. The latency probe updates the DNS servers with the clients' latency data. The DNS server uses the latency test data updates to determine the closest server to a client. | 08-20-2009 |
| 20090259853 | DYNAMIC MULTIMEDIA FINGERPRINTING SYSTEM - 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. | 10-15-2009 |
| 20090327489 | GLOBAL TRAFFIC MANAGEMENT SYSTEM USING IP ANYCAST ROUTING AND DYNAMIC LOAD-BALANCING - A method and apparatus for serving content requests using global and local load balancing techniques is provided. Web site content is cached using two or more point of presences (POPs), wherein each POP has at least one DNS server. Each DNS server is associated with the same anycast IP address. A domain name resolution request is transmitted to the POP in closest network proximity for resolution based on the anycast IP address. Once the domain name resolution request is received at a particular POP, local load balancing techniques are performed to dynamically select the appropriate Web server at the POP for use in resolving the domain name resolution request. Approaches are described for handling bursts of traffic at a particular POP, security, and recovering from the failure of various components of the system. | 12-31-2009 |
| 20100005175 | DISTRIBUTED ON-DEMAND COMPUTING SYSTEM - A method and mechanism for a distributed on-demand computing system. The system automatically provisions distributed computing servers with customer application programs. The parameters of each customer application program are taken into account when a server is selected for hosting the program. The system monitors the status and performance of each distributed computing server. The system provisions additional servers when traffic levels exceed a predetermined level for a customer's application program and, as traffic demand decreases to a predetermined level, servers can be un-provisioned and returned back to a server pool for later provisioning. The system tries to fill up one server at a time with customer application programs before dispatching new requests to another server. The customer is charged a fee based on the usage of the distributed computing servers. | 01-07-2010 |
| 20100125649 | Dynamic Image Delivery System - A dynamic image delivery system receives a client request for an image at an image caching server. The image caching server measures the client's network access speed and looks for an appropriate pre-rendered copy of the requested image that is rendered for the client's network access speed in local storage. If the appropriate rendered copy is found, then the image caching server sends the rendered image to the client. If it is not found, then the image caching server dynamically renders a copy of the image and sends it tot he client. | 05-20-2010 |

| 20090132648 | CONTENT DELIVERY AND GLOBAL TRAFFIC MANAGEMENT NETWORK SYSTEM - 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. | 05-21-2009 |
| 20090172145 | INTEGRATED POINT OF PRESENCE SERVER NETWORK - A network of point of presence servers allows a customer to organize their web site by functions where functions are mapped into domain names. The functions have requirements that define what is needed by a server to satisfy the function. The domain names are mapped into resources or servers that can be addressed by the domain name and that satisfy requests for the function that domain name has been defined to support. This method of organization allows individual elements of a web page to be retrieved from different resources and gives the name server the control to direct users to an available and optimal server for a given resource. | 07-02-2009 |
| 20110167111 | METHOD FOR OPERATING AN INTEGRATED POINT OF PRESENCE SERVER NETWORK - A method for operating a network of point of presence servers sharing a hostname includes receiving a request from a user for a web page at a first web address, determining traffic loads of a plurality of customer web servers, determining a customer web server from the plurality of customer web servers, the customer web server having a traffic load lower than traffic loads of remaining customer web servers, directing the request from the user to the customer web server, receiving a request from the user for static content on the web page at a second web address, determining the point of presence server from the network of point of presence servers that is appropriate for the request, the point of presence server having service metrics more appropriate than service metrics of remaining point of presence servers from the network. | 07-07-2011 |
