MPLS-TP

Next generation critical communications

Dependable communications is the lifeline of countless services in the digital era. DNWP packet switched technologies empower IP based communication services without compromising security.

DNWP Connection Master offers a smooth evolution path from existing critical communications means towards next generation technologies. It enables parallel SDH and MPLS-TP services with superior flexibility.

Fingrid, Finland’s transmission system operator, relies on DNWP’s MPLS-TP solutions across its critical network infrastructure — read more about the collaboration.

Why MPLS-TP is ideal for power utility OT networks

MPLS-TP (Multiprotocol Label Switching – Transport Profile) provides deterministic, secure and highly reliable communication for mission-critical power utility networks.

1. Deterministic and symmetrical latency
MPLS-TP uses statically provisioned, bidirectional LSPs (Label Switched Paths) ensuring identical forward and return paths. This enables predictable latency and meets strict requirements of differential teleprotection schemes.

2. High availability and fast protection
MPLS-TP supports high availability (≥99.999%) with built-in redundancy and protection switching below 50 ms, ensuring uninterrupted operation of critical services.

3. OT-aligned operational model
MPLS-TP operates without a dynamic control plane.Services are provisioned centrally via NMS, reducing complexity and aligning with traditional utility network operations.

4. Legacy service support (TDM over Packet)
MPLS-TP enables seamless migration from legacy systems using SAToP and CESoP, allowing E1, serial SCADA and protection interfaces to operate over packet networks.

5. Accurate timing and synchronization
MPLS-TP supports IEEE 1588v2 (PTP) and SyncE.
Deterministic transport minimizes delay variation, enabling precise timing for synchrophasors and grid automation.
