Foundation Component
Topology and Traffic Engineering. Real-time topology awareness for traffic engineering decisions.
Features
Real-time topology discovery and what-if analysis to optimize your network infrastructure.
Automatically build and maintain an accurate, real-time model of your network topology with instant change detection.
Explore the topology guideFull topology support for SR-MPLS and SRv6 domains, including Flexible Algorithm awareness for constraint-based traffic engineering.
Flex-Algo referenceExpose topology data through a northbound API with real-time streaming updates, enabling seamless consumption by controllers, orchestrators, and third-party systems.

registry.arolo-solutions.com/prelude/prelude-te:latestManual topology maps
Static diagrams maintained by hand in Visio or wikis, outdated within days of any network change.
Auto-discovered, real-time topology
Continuously built and updated from live network data, with instant detection of link, node and adjacency changes.
Blind traffic engineering
TE decisions based on static capacity plans and spreadsheets, with no visibility into actual path utilization or constraint violations.
Real-time TE topology awareness
Full SR-MPLS, SRv6 and FlexAlgo topology data (metrics, constraints and segment lists) available in real time for controllers and orchestrators to act on.
Topology locked in the NMS
Topology data trapped inside a single management tool, inaccessible to controllers, orchestrators or custom automation.
Open API with real-time streaming
Northbound API exposes topology to any consumer (SDN controllers, orchestrators or third-party systems) with streaming updates on every change.
Interface UP, routing down
An IGP adjacency dies while the interface stays operationally UP — MTU mismatch, hello timeout, authentication failure, control-plane glitch. Telemetry shows green; traffic blackholes until someone notices.
Direct IGP adjacency alerts
Adjacency state monitored at the protocol level. The moment a neighbor drops — even with the interface still UP — an alert fires, surfacing routing failures that interface counters can never reveal.
Drive Prelude TE from any AI tool that speaks the Model Context Protocol — Claude Code, Cursor, Codex and others. Query topology, inspect peers and trigger workflows straight from your assistant.
