Abstract
A network switch, configured for performing layerand layerswitching in an Ethernet (IEEE 802.3) network without blocking of incoming data packets, includes a switching module for performing layerand layer(specifically Internet Protocol) switching operations, and a plurality of network switch ports, each configured for connecting the network switch to a corresponding subnetwork. The switching module includes address tables for storing address information (e.g., layerand layeraddress and switching information). The network switching module is configured for performing prescribed layerswitching that enables transfer of data packets between subnetworks, bypassing a router that normally would need to manage Internet protocol switching between subnetworks of the network. Hence, the network switch performs Internet Protocol switching for intranetwork (i.e., inter-subnetwork) traffic, improving efficiency of the router by enabling the router resources to support more subnetworks.
