Abstract: Aspects of the present disclosure are directed to systems, methods, and computer readable media for dynamic data transfer rate control. One method includes alternating a network device between a plurality of supported data transfer rates that are supported by the network device to achieve an unsupported data transfer rate that is not supported by the network device. Another method includes adding one or more dummy work descriptors to a data stream, and transmitting the data stream including the one or more dummy work descriptors at a supported data transfer rate that is supported by a network device to achieve an effective unsupported data transfer rate that is not supported by the network device.

Abstract: A computerized system for efficient interaction between a host, the host having a first operating system, and a second operating system, the system comprising a subsystem on the second operating system which extracts data, directly from a buffer which is local to the host, wherein the system is operative for mapping memory from one bus associated with the first operating system to a different bus, associated with the second operating system and from which different bus the memory is accessed, thereby to emulate a connection between the first and second operating systems by cross-bus memory mapping.
