Abstract
A network switch, configured for performing layer and layer switching in an Ethernet (IEEE 802.3) network without blocking of incoming data packets, includes network switch ports, each including a port filter configured for obtaining and filtering relevant layer and layer information from a received layer frame. Each port filter, upon filtering the relevant layer and layer information from a received layer frame, outputs the relevant layer and layer information to switching logic, enabling the switching logic to perform layer processing to determine a layer switching operation to be performed on the received layer frame. Hence, the switching logic performs the layer processing based on the relevant layer and layer information, without the necessity of parsing the received layer and layer information by the switching logic.
