MPLSNetz

MPLSNetz is a term used in networking literature to describe an MPLS-based backbone architecture designed to support scalable and deterministic routing across large networks. It relies on Label Switched Paths (LSPs) to forward labeled packets, enabling efficient traffic engineering, fast reroute, and clear separation between control and forwarding decisions. The approach is typically deployed to enable high-capacity interconnections, multi-tenant services, and reliable transport across metropolitan and national networks.

Core components of MPLSNetz include Label Switch Routers (LSRs) and Label Edge Routers (LERs), which establish and switch labeled paths. LSPs can be set up using RSVP-TE or, in newer deployments, segment routing. Interior gateway protocols such as OSPF or IS-IS handle IGP routing, while MP-BGP distributes VPN routes across the network. In some deployments, MPLS-TP (Transport Profile) is used to emphasize carrier-grade OAM features for transport-like service guarantees.

Architecturally, MPLSNetz often adopts a core-edge or spine-leaf design to scale both capacity and reach. Integration with software-defined networking (SDN) controllers is common, enabling centralized path computation, service orchestration, and dynamic TE adjustments while preserving the efficiency of the MPLS data plane.

Services commonly deployed over MPLSNetz include L3VPNs and L2VPNs (such as VPLS or VPWS), providing isolated, scalable connectivity for customers or business units. QoS and traffic engineering support enable SLA-based performance, while multicast and other advanced features add flexibility for diverse applications. Operational considerations focus on OAM visibility, fault management, and interoperability across equipment and vendor ecosystems.
