Abstract: Systems, computer program products, and methods are described for secure data transmission. An example system includes a first end-point device, an intermediate device, and a second-end point device. The first end-point device determines the format requirements of the communication link between the first end-point device and the intermediate device, and the communication link intermediate device and the second end-point device. Based on the format requirements, the first end-point device configures the data packet for transmission, such that the data packet, when received at the intermediate device, is re-configured and routed to the second end-point device. When the second end-point device receives the data packet, it verifies the data packet to confirm that the packet has maintained its integrity throughout transit.

Abstract: Systems and methods herein are for a Non-Transparent Bridges (NTBs) that are scalable and configurable to use equally sized or spaced windows and a common lookup database for remapping writes without completions. The equally sized or spaced windows in the address space are addressable by a starting address and a size to support communication between host machines or endpoints. The common lookup database is to allow selection of one the windows associated with a mapping between address spaces of different domains and is also to accept remapping writes through the at least one NTB to modify the mapping without need for a completion to be returned to a source of the remapping writes.

Abstract: An apparatus includes a processor, a first interface configured to connect to a bus of the apparatus, a second interface configured to communicate over a packet network, and circuitry. The circuitry is configured to, in a first operational mode, exchange data between the processor and one or more remote devices over the packet network, via the second interface, and in a second operational mode, monitor the bus using the first interface, detect a predefined trigger event occurring on the bus and, in response to detecting the trigger event, log one or more transactions on the bus that are adjacent to the trigger event and generate one or more protocol-analysis packets comprising at least part of the logged transactions.
