US Patent 7209485 Method and arrangement for controlling data packets

A method and an arrangement for controlling data packets in a computer network forwards particular data packets, from the whole of a data stream, via a gateway with a host processor. The particular data packets are forwarded to subsystems for further processing, and data packets are introduced into the data stream by the subsystems via the gateway. In this context, a data packet router forwards the data packets directly, i.e. past the host processor, to the subsystems, and the data packet router introduces the data packets coming from the subsystems directly into the data stream using an interface device.
