  • Patent number: 9686320
    Abstract: Technologies, systems, and methods for ordered message delivery that avoid message races or crisscrosses between communicating nodes. For example, if Node A sends message 3 towards Node B and, shortly thereafter, Node B sends message X to Node A, Node A would like to know whether or not message X reflects Node B's state after receiving message 3. If Node B received message 3 prior to sending message X, then proper state may be maintained between the nodes. But if messages 3 and X crisscrossed, or if message 3 was never properly received by Node B, then the state between the nodes may be corrupt. Technologies, systems, and methods are provided to avoid such corruption.

  • Patent number: 9524344
    Abstract: A user interface may be utilized to allow a user to control display properties of online ad content on a hosting webpage (e.g., hosting ads from one domain on a webpage from a different domain). This may be accomplished by creating a cross-domain frame in the hosting webpage, which can contain the ad content. An instantiation of a user interface may be created on the hosting webpage that has an ability to control display properties of the cross-domain frame, thereby controlling display properties of the ad content in the cross-domain frame. Further, a task manager may be utilized as part of the user interface to facilitate a host of the hosting webpage to manage ad content.

  • Patent number: 9367257
    Abstract: An exemplary system includes a front-end component to receive requests for resources in a data center and configured to associate each request with identifying information, to locate one or more resources for each request and to store, in a log file, the identifying information and information about the location of the one or more resources; one or more distributed computation and storage components to acquire log file information and configured to analyze log information to decide if one or more resources associated with one or more requests should be migrated to a data center in a different geographical location; and a location service component to receive decisions made by the one or more distributed computation and storage components and configured to inform the front-end component when a decision causes one or more resources to be migrated to a data center in a different geographical location to thereby allow the front-end component to re-direct future requests for the one or more migrated resources to t

  • Patent number: 8966121
    Abstract: An exemplary method includes booting a computing device, in response to the booting, accessing a file that includes domain names and resolving at least one of the domain names by issuing a request to a server where the resolving occurs as a background process. An exemplary method includes receiving a notice to invalidate client DNS resolver cache information for a domain name, accessing a list of client subscribers to an invalidation service for the domain name and issuing an instruction to the client subscribers to invalidate their respective client DNS resolver cache information for the domain name. An exemplary method includes receiving a request to resolve a domain name, resolving the domain name and transmitting information for the resolved domain name and additional information for at least one other domain name. Other methods, devices and systems are also disclosed.

  • Patent number: 8707318
    Abstract: The application discloses a generic partitioning manager for partitioning resources across one or more owner nodes. In illustrated embodiments described, the partitioning manager interfaces with the one or more owner nodes through an owner library. A lookup node or application interfaces with the partitioning manager through the lookup library to lookup address or locations of the partitioned resources. In illustrated embodiments, resources are partitioned via the partitioning manager in response to lease request messages from an owner library. In illustrated embodiments, the lease grant message includes a complete list of the leases for the owner node.

  • Patent number: 8458298
    Abstract: An exemplary failover module includes (a) instructions to respond to a connection problem to a host server at an IP address by selecting a different IP address from a cached list of IP addresses for a domain name associated with the host server and (b) instructions to return the selected, different IP address to future name queries where the instructions to respond, the instructions to initiate, and the instructions to return execute at an operating system level of a computing device configurable to connect to at least one of a plurality of host servers. Such a module may include instructions to optionally initiate a connection to a host server at the selected, different IP address. An exemplary failover module may optionally select an IP address based in part on Internet Location Coordinates (ILCs) where the host servers reside in an ILC enhanced Domain Name System (DNS). Other methods, devices and systems are also disclosed.
