High speed packet capture
Packets can be read from a network interface into an application using a single kernel copy. In one embodiment, the invention includes a receiver packet memory to store captured packets, and a network interface driver operating in a kernel of a device to read packets captured by network interface hardware into the kernel by storing captured packets in the receiver packet memory. Then, an application interface can expose the receiver packet memory to an application executing on the device by representing the receiver packet memory as a virtual file.
