Translation: Multiprotocol Label Switching (MPLS) is a new IP backbone of network technology. MPLS introduces the concept of
connection-oriented label switching on the connectionless IP network, combines the third-layer routing technology
with the second-layer switching technology, and gives full play to the flexibility of IP routing and the simplicity of layer-2 switching.
The MPLS layer is located between the network layer and the link layer, as shown in the following figure:
MPLS is widely used in large-scale networks, like OLT and other routing and forwarding equipment, and it has the following benefits:
(1) In the MPLS network, the device forwards the message according to the short and fixed-length labels, which saves the tedious process
of finding IP routes through software, and provides a high-speed and efficient way for data transmission in the backbone network.
(2) MPLS is located between the link layer and the network layer. It can be built on top of various link layer protocols (such as PPP, ATM,
frame relay, Ethernet, IPX, etc.) to provide connection-oriented services, compatible with various existing mainstream network technologies.
(3)MPLS is widely used in VPN, traffic engineering, QoS, and other applications because it supports multilayer labels and connection-oriented features.
(4)On the basis of the MPLS network, it can provide a variety of services to customers due to its adaptability.
