Techopedia Explains Tag Switching (Label Switching)

Tag switching, which integrates router and switch functionalities, is a proprietary Cisco protocol. Packets are tagged with particular information and routed to their destination via routers (tag-edge routers), switches (tag switches) and protocols (tag protocols). Tag switching provides dynamic functions, including vendor and network IP scalability.
