Abstract: Techniques to process a query and perform a join of tables that are distributed across nodes of a network. The join can be performed by analyzing a Where clause. An active flag structure can have flag values that identify table entries satisfying criteria of the Where clause. Keys of surviving entries of a first table can be used to generate a request for a second table to be joined. The request can be for second flags for the second table when the Where clause has criteria for the second table. A response can be used to update the first flags to change a first flag to False. After updating, data can be retrieved for first flags that are True. Requests can use identifiers associated with the first table that identify a location for sending the request, e.g., using RDMA or MPI.

Abstract: Systems and methods dynamically adapt network policies for mobile devices by accessing context-based values to allocate or restrict capabilities on the mobile devices or within the network. Context-based values may include position or velocity as well as more general environment features such as proximity of other devices, the presence or absence of other wireless signals or network traffic, parameters measured by local or remote sensors, user credentials, or unique user or signal inputs to the device. Relevant capabilities may include access to hardware and software interfaces and related parameter sets including priority settings.
