MPLS L3VPN Overview

MPLS
applying the MPLS technology to network routing and switching
equipment to simplify core routers.
switching combined with traditional routing technologies to im-
plement IP-based VPN.
MPLS VPN can be used to construct broadband Intranet and Ex-
tranet and can meet multiple flexible service requirements.
MPLS VPN can utilize the powerful transmission capability of a com-
mon backbone network, reduce the construction costs of the In-
tranet, greatly improve the operation and management flexibility
of user's networks, and meanwhile can meet the requirements of
users for secure, realtime, broadband and convenient information
transmission.
MPLS VPN
In an IP-based network, MPLS has the following advantages:
Advantages
� Reducing costs
MPLS simplifies the integration technology of ATM and IP, effi-
ciently combines the Layer 2 and Layer 3 technologies, reduces
costs and protects user's investment at earlier stages.
� Improving resource utilization
Since label switching is used on the network, user's LANs at
different points can use repeated IP addresses to improve the
utilization of IP resources.
� Improving network speed
