Technology Briefing MPLS* provides the “Best-effort Delivery”. It speeds up the data delivery, improves the packet Qo. S 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 3 1 40 3 1 47. 350 3 47. 1 2 1 47. 2 2 IP 47. 1. 1. 1 Note: DGS-3620 will support MPLS in the future

Technology Briefing MPLS L 3 VPN MPLS VPN: Allows Service Provider to to plan, provision, and manage for IP VPN service on the fast switching MPLS network MPLS L 3 VPN = VPN + BGP + MPLS BGP to exchange VPN and label info 10. 10. 10. 0/24 CE 1 Customer A VRF 1 PE 1 CE 2 10. 10. 0/24 Customer B VRF 2 MPLS tag switching Customer A 10. 10. 0/24 VRF 1 P CE 3 PE 2 VRF 2 MPLS tag switching CE 4 10. 10. 0/24 MPLS Network Customer routing information is exposed to Service Provider VRF(VPN Routing & Forwarding Instance): routing table instance for each customer Customer B 10. 10. 0/24

Technology Briefing MPLS L 2 VPN: VPWS & VPLS VPWS (Virtual Private Wire Services) is point-to-point. VPLS (Virtual private LAN service) is multipoint. Carrier Ethernet logically connects to MPLS core via Q-tag, Q-in-Q or simple p 2 p MPLS tunnels MPLS core carries pure Ethernet over MPLS without customer Layer 3 routing control Customer routing information is NOT exposed to Service Provider
