MPLS stands for "Multi-Protocol Label Switching" packet-switching VPN technology. With MPLS, incoming data packets are assigned a "label" by a "label edge router (LER)". Such labeled packets are forwarded along a "label switch path (LSP)". Along a LSP, each "label switch router (LSR)" forwards a packet based solely on the instructions of the label.

Use an IP VPN deploying MPLS technology to mark, classify, and monitor IP packets. At the ingress side of MPLS network, LER examines and determines whether the incoming packets should be labeled. LER classifies incoming IP traffic with an MPLS label. The LER converts IP packets into MPLS packets and back. When the MPLS packets leave the LER, they are examined by LSR for the presence of labels. LSR will then swap labels according to label instructions.

With MPLS packet labeling method, which is similar to the processing of labels used in Frame Relay and ATM, security level of MPLS IP VPN service is compatible with ATM or FR security level. Users familiar with ATM and FR services can feel comfortable with MPLS security performance.
