NorthStar Controller

Multilayer SDN control puts an end to overprovisioning

This industry-first NorthStar traffic optimization WAN SDN controller automates the creation of traffic-engineering paths across the network, increasing network utilization and enabling a customized programmable networking experience. With the power of Junos OS, WANDL optimization algorithms, and transport abstraction, NorthStar Controller enables efficient design, bringing new levels of control and visibility that help you avoid costly over provisioning.

    A powerful and flexible solution, NorthStar Controller provides granular visibility into, and control over, IP/MPLS flows in large service provider and enterprise networks. Using NorthStar Controller, operators can optimize their network infrastructure through proactive monitoring and planning, and dynamically create explicit routing paths using a global view that’s based on user-defined constraints.

    Network managers need to move to a more efficient operational model to rein in spending. Capacity upgrades should be targeted, service driven, and capable of adapting dynamically to constantly evolving customer needs in real time. NorthStar Controller makes this goal a reality by providing:

    • Comprehensive network planning, capacity, and topology analysis across Layers 1–3.

    • Runtime and standards-based traffic engineering for Path Computation Element Protocol (PCEP)-compliant routers.

    • Graphical and programmable REST APIs for customized integration into existing network operator environments.


    • Provides complex interdomain path computation and network optimization services.
    • Employs sophisticated, industry-leading path computation algorithms.
    • Addresses multilayer optimization with multiple user-defined constraints.
    • Provides specific ordering and synchronization of paths that are signaled across routed network elements.
    • Offers a global view of network state for monitoring, management, and proactive planning.
    • Features predictable, deterministic network state within a margin of error for demand forecasts.
    • Minimizes distributed state and increases efficiency of existing network elements by offloading control-plane processing.
    • Creates a foundation for additional centralized network infrastructure services through an API for the network.
    • Simplifies operations by enabling SDN programmability control points across disparate network elements.
