  • Patent number: 7185052
    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.

  • Patent number: 7155723
    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.

  • 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.

  • Patent number: 6851924
    Abstract: A crack-resistant vane segment assembly member for an industrial turbine engine is disclosed. The vane segment includes at least one internally-cooled body portion and inner and outer shroud portions. The body portions include end regions characterized by blending and transition zones that ensure heat is transferred at a non-crack-inducing rate from the shroud portions to the body portions. The vane segment assembly also includes a cooling arrangement that reduces the impact of thermal gradient-induced stresses acting at the interface between the body portions and shroud portions. The cooling arrangement cooperates with the transition and blending zones to produce synergistically-enhanced crack resistance properties.

  • Patent number: 6754706

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.

  • Patent number: 6754699
    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: 6694358
    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.

  • Publication number: 20030188176
    Abstract: A method, system and computer program product for remotely booting devices. A deployment server may remotely transmit authentication parameter(s), e.g., public key, secret key, to a service unit configured to establish a private connection between server blades and the deployment server. The service unit may remotely install the authentication parameter(s) onto the server blade(s) to be booted by either the deployment server or another boot server. By the service unit remotely installing the authentication parameter(s) onto the server blade(s), the need to manually install them during each network boot operation may be alleviated. By remotely transmitting authentication parameter(s) instead of manually installing them on the devices to be booted during each network boot operation, the deployment server may be able to generate unique authentication parameter(s), e.g., public/private key pair, secret key, for each network boot operation thereby substantially reducing the exposure to replay attacks.

  • Publication number: 20030065763
    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.

  • Patent number: 6484143
    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.
