17. IP 47.1.1.1 Technology BriefingMPLS • MPLS* provides the “Best-effort Delivery”. It speeds up the data delivery, improves the packet QoS and solves the burden of IP routing • MPLS adopted the core idea of ATM. It locates itself between IP layer and data link layer and takes the responsibility of carrying any traffic over itself • What MPLS learns from ATM: • Thinking of label switching • Using Local Label instead of global IP address 1 47.1 3 3 40 2 1 1 50 47.3 3 47.2 2 Note: DGS-3620 will support MPLS in the future

18.
