Abstract
A method of broadcasting a packet to the ports belonging to one VLAN of a network, whereas the network has multiple network switches. Each network switch has its own local ports and a local VLAN table. Each local VLAN table stores local port membership of its network switch, and switch membership per VLAN identifier. The local VLAN table is accessed by a VLAN identifier which is stored in the packet, and retrieves the local port membership and switch membership associated with the VLAN identifier. A copy of the packet is provided to each local port and to each switch retrieved from said local VLAN table.
