MPLS (Multiprotocol Label Switching) is a switching protocol that is commonly used in backbone or label edge routers to optimize packet exchange by creating labels for each packet. This allows for faster and more efficient routing of packets through the network. ISDN (Integrated Services Digital Network), SONET (Synchronous Optical Network), and ATM (Asynchronous Transfer Mode) are all communication protocols, but they are not specifically designed for switching and optimizing packet exchange like MPLS.
