Abstract: A system includes reception of a database query, determination of result set output columns associated with the database query, and determination, for each of the determined result set output columns, of one or more data sources associated with the result set output column. Sensitivity information is determined for each of the one or more data sources based on metadata, and result set sensitivity information is determined based on the determined sensitivity information. A result set is determined based on the database query, and the result set and the result set sensitivity information are transmitted.

Abstract: A method and devices for reducing the delay in end-to-end delivery of network packets may be achieved by having the transmission (TX) side of the device, tag each cell with a unique packet identifier and with a byte offset parameter where the tagging allows the reception (RX) side of the destination device to perform on-the-fly assembly of cells into packets by directly placing them at corresponding host buffer, and the method may be done for multiple packets concurrently, and hence store and forward buffering is not needed in either the source or the destination devices and the lowest possible end-to-end cut-through latency is achieved.

Abstract: The invention relates to a memory aggregation device for storing a set of input data streams and retrieving data to a set of output data streams, the memory aggregation device comprising: a set of first-in first-out (FIFO) memories each comprising an input and an output; an input interconnector configured to interconnect each one of the set of input data streams to each input of the set of FIFO memories according to an input interconnection matrix; an output interconnector configured to interconnect each output of the set of FIFO memories to each one of the set of output data streams according to an output interconnection matrix; an input selector; an output selector; and a memory controller.

Abstract: A method for packet reassembly and reordering, comprising: receiving a cell sent by a source port, wherein the cell carries a Source Identification (SID), a packet sequence number and a cell sequence number; preprocessing the received cell according to the SID to determine whether the cell shall be inserted into a packet reassembly database; ordering cells in the packet reassembly database according to the packet sequence number to obtain a correctly ordered packet; if the correctly ordered packet is a complete packet, ordering the cells of the correctly ordered packet according to the cell sequence number to obtain correctly ordered cells; and performing a packet reassembly for the correctly ordered cells. Correspondingly, a network device and a communication system are provided.

Abstract: An enterprise computing system may utilize a management infrastructure that interacts with protected services in the system. The management infrastructure accepts requests through an anti-tamper procedure that specifies a tamper event, a crucial service to be protected, and a remedial action that may be applied when the tamper event occurs on the protected service. The anti-tamper procedure may be created by a system administrator and distributed to one or more client devices in the system. The management infrastructure monitors a protected service in accordance with the operations and actions specified in the anti-tamper procedure thereby ensuring that the integrity of the system is preserved.
