摘要： 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.

摘要： 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.

摘要： 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.

摘要： A technique for identifying dependencies of an application upon a given security context includes monitoring security checks generated by the application. The security checks requiring elevated rights are identified and the state of execution of the application corresponding to the identified security checks may be logged. The security checks requiring elevated rights may be identified by monitoring access checks, monitoring privilege checks, checking user/group identifiers against a list of known identifiers associated with elevated rights, or the like.

摘要： 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.

摘要： A system and method that increases the capacity of a wireless network using frequency diversity. A user switches between channels of a network using a single network interface card in such a manner that nodes desiring to communicate overlap while disjoint communications mostly do not overlap. A driver is inserted into a device's networking stack and controls the network interface card using a plurality of virtual wireless network adapters. Packets for a recipient are queued when the recipient is not accessible on the node's channel. In one embodiment where multiple nodes are switching in and out of channel, the method changes part of a nodes channel hopping schedule to ensure concurrent connectivity in a channel for at least a brief time period such that packets can be received/transmitted with desired nodes.
