A system and method for handling a digital electronic flow between a first and second entity in which a flow policy is determined that is to be applied to the flow and the flow is then directed along a path in accordance with the policy. An ID is supplied for each flow and a tag associated with each flow which indicates the policy to be applied to its associated flow. Flows are also associated with one another, with associated flows having associated policies. In particular the flow may be processed or forwarded. The path may include a graph structure and virtual applications.

System and method for processing and forwarding transmitted information

A VIRTIO Relay Program allows packets to be transferred from a Network Interface Device (NID), across a PCIe bus to a host, and to a virtual machine executing on the host. Rather than an OvS switch subsystem of the host making packet switching decisions, switching rules are transferred to the NID and the NID makes packet switching decisions. Transfer of a packet from the NID to the host occurs across an SR-IOV compliant PCIe virtual function and into host memory. Transfer from that memory and into memory space of the virtual machine is a VIRTIO transfer. This relaying of the packet occurs in no more than two read/write transfers without the host making any packet steering decision based on any packet header. Packet counts/statistics for the switched flow are maintained by the OvS switch subsystem just as if it were the subsystem that had performed the packet switching.
