Management of data communication between a peripheral device and host computer system is provided. A physical interface for communicating data between a peripheral device and applications executing on the host is opened and controlled by a software module. First and second virtual interfaces of the software module are exposed to an operating system of the host, and the operating system exposes the first and second virtual interfaces to a first application and a second application executing on the host. The first virtual interface is used for communicating data between the peripheral device and the first application through the physical interface, and the second virtual interface is used for communicating data between the peripheral device and the second application through the physical interface. Management of data communication between the peripheral device and the first application and between the peripheral device and the second application is thereby provided.

A network security device which acts as an “airlock” for traffic between a communications device and a network. Data is screened using rules based analysis by the security device to counter various threats, including viruses, phishing, attempts to “hijack” communications, communications with known malicious addresses or unknown addresses, and transmission of sensitive information. Data packets can be reassembled into files for screening, and decoded or expanded as necessary, but is never executed. The data path for the data being screened is kept separate from the operations of the network security device itself, so that the device is incorruptible—its programming cannot be compromised from outside sources. Updates for rules and entry of sensitive data for screening, etc., must be done through a physical interface, not via the normal data communications channel. The device is invisible—it cannot be “seen” by the network, and thus cannot be attacked.

Methods and systems for determining paths for flows within a multi-stage network made up of clusters of processing nodes. The flow paths may be determined without knowledge of whether or not packets of a particular flow will actually traverse specific ones of the clusters within the multi-stage network. In various implementations, the nodes of the multi-stage network may be coupled to one or more physical network switches through respective physical interfaces and a virtual connectivity grid superimposed thereon and configured through the use of a flow routing framework and system management framework to group the nodes into a number of clusters. The nodes of each cluster are configured to perform similar packet processing functions and the clusters are interconnected through virtual networks to which the nodes are communicatively coupled via virtual interfaces overlaid on top of the physical network interfaces.

In an embodiment, an interface enables an electric vehicle to communicate with an electric power supply device without specific hardware by modulating the power transfer between the electrical load and an electric power supply. In another embodiment, a system provides for arbitrating a smart chargepoint includes a first smart charging module implemented on equipment located inside a vehicle.

The present invention provides systems and methods for providing data transmission speeds at or in excess of 10 gigabits per second between one or more source devices and one or more destination devices. According to one embodiment, the system of the present invention comprises a first and second media access control (MAC) interfaces to facilitate receipt and transmission of packets over an associated set of physical interfaces. The system also contemplates a first and second field programmable gate arrays (FPGA) coupled to the MAC interfaces and an associated first and second memory structures, the first and second FPGAs are configured to perform initial processing of packets received from the first and second MAC interfaces and to schedule the transmission of packets to the first and second MAC interface for transmission to one or more destination devices. The first and second FPGAs are further operative to dispatch and retrieve packets to and from the first and second memory structures. A third FPGA, coupled to the first and second memory structures and a backplane, is operative to retrieve and dispatch packets to and from the first and second memory structures, compute appropriate destinations for packets and organize packets for transmission. The third FPGA is further operative to receive and dispatch packets to and from the backplane.
