Abstract
An address translation mechanism quickly and efficiently renders forwarding decisions for data flames transported among ports of a high-performance switch on the basis of, inter alia, virtual local area network (VLAN) associations among the ports. The translation mechanism comprises a plurality of forwarding tables, each of which contains entries having unique index values that translate to selection signals for ports destined to received the data frames. Each port is associated with a unique index value and a VLAN identifier to facilitate multicast data transfers within the switch at accelerated speeds and addressing capabilities.
