MPLS VPN
When it comes to "MPLS replacement", it usually means abandoning the traditional MPLS protocol in the VPN architecture and using other technologies to achieve equivalent functions.

1. Cost optimization: avoid dedicated MPLS hardware and use white box switches + open source protocols.
2. Cloud native adaptation: traditional MPLS is difficult to seamlessly integrate cloud networks.
3. Simplified operation and maintenance: MPLS protocol stack is complex (LDP/RSVP-TE+MP-BGP), and alternatives are lighter.
4. Scalability requirements: Internet-level VPN deployment requires higher elasticity.
