Live Multilayer Map


View How IP Links Are Routed and Follow Cross-Layer Connections

Discovery LIGHT

What It Does

  • Discovers the L0-L3 topology
  • Shows how the layers are interconnected
  • Displays optical connections and MPLS tunnels
  • Displays end-to-end IP traffic
  • Highlights congestion on IP links and failures at both layers
  • Displays all the information in an easy-to-use 3D UI

Operator Benefits

  • Automatic, reliable collection of network topology
  • Fewer human errors, especially those that occur between different network elements and different vendor inter-connections
  • Improved troubleshooting by both IP and optical operations groups
  • Ability to understand the impact of a failure on customer traffic in any layer
  • Ability to share network information between different planning groups (such as IP/MPLS and optical) to better utilize networks assets
  • Enablement of new services that are fully diverse and committed to higher SLAs


Sedona’s NetFusion Discovery platform automatically acquires topology, services, and traffic information from both Optical and IP/MPLS layers, and creates a live map of both layers and their interconnections.
The most basic multilayer capability is to understand how the layers map one to the other. Accurate mapping is key to changing the network without risking inadvertent service loss.

At the heart of Sedona’s network discovery is an intuitive 3D UI that allows operators to navigate through the network, see the various layers (IP, OTN and DWDM), and collect information elements. These include an IP/MPLS layer site (including the core and edge routers it encompasses), an optical site, an IP link, an optical link, andthe crosslink connecting the layers.

The UI also allows users to see how the layers interconnect. For example, it shows how an IP link maps to the optical path that supports it. Users can see how IP traffic and MPLS tunnels are mapped over the multilayer network, giving them visibility down to the Optical layer.
Cross-layer mapping is a challenging task, mainly since no standards exist for it and since transponders cannot peek into the Ethernet frame. Sedona uses a patent-pending approach for correlating various existing information to arrive at an accurate mapping.
