Abstract
An edge switch for an Ethernet network maintains look-up tables of media access control addresses and network addresses for local sources and destinations at least two sub-nets, so that it can forward packets directly even when the local source and destination are on different sub-nets and forwards packets to a core router when the destination is not local to the edge switch.
