MPLS

Multiprotocol Label Switching

MPLS (Multiprotocol Label Switching) provides an all-IP network that enables high-speed processing and management of large volumes of railway system data traffic by using a routing technology based on labels rather than network addresses. It complies with IETF standards.

Features

A system optimized for LTE-R voice call backbone networks, enabling faster packet delivery than IP routing by attaching short numeric labels instead of using IP addresses.

Configuration

Composed of Label Edge Routers that attach/remove labels at MPLS network boundaries and Label Switching Routers that forward packets at high speed within the internal network.

Functions

Transmits packets at high speed by referencing only the labels without IP header analysis. Supports QoS control, Traffic Engineering (TE), MPLS-VPN and Fast Reroute (FRR).

Effects

  • Improved Performance
    Enhances network performance by increasing packet processing speed and minimizing delay.

  • Efficient Network Operation
    Optimizes resource usage and balances network load.

  • Reduced Operating Costs
    Decreases the need for additional equipment by improving line efficiency and enabling virtual router (VRF) configuration through VPN setup.

  • Expected Benefits
    Supports various network protocols, traffic types (voice, data, streaming, etc.), and service architectures.
