    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： Described herein is a system that includes a location determiner component that receives a first geographic location of a personal computing device of a first individual, wherein the first geographic location is indicative of a current geographic location of the first individual. The system also includes an estimator component that receives a second geographic location that is different from the first geographic location. The estimator component determines an estimated time of arrival for the first individual at the second geographic location based at least in part upon the received first geographic location, wherein the estimator component outputs the estimated time of arrival to a second individual.

    摘要： 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 the data center in the different geographical location. Various other devices, systems and methods are also described.

    摘要： An exemplary method for load balancing includes accessing a range of values for IP addresses associated with a virtual IP address associated with a domain name; selecting, using a local statistical algorithm, a value in the range; and, based at least in part on the selected value, connecting to a remote resource at one of the IP addresses. In such a method, a client can perform local load balancing when connecting to one of many fungible resources “behind” a virtual IP address. With many such clients, the task of load balancing is distributed as opposed to being centralized at a server farm or cluster. Other methods, devices and systems are also disclosed.

    摘要： Wireless adapters are installed on one or more general purpose computing devices and are connected via a wireless network in an enterprise environment. The adapters are densely deployed at known locations throughout the environment and are configured as air monitors. The air monitors monitor wireless signals transmitted between transceiver devices and access points and records information about these signals. One or more analysis or inference engines may be deployed to analyze the signals received from the air monitors to obtain optimum performance and connectivity information about the wireless network.
