Building on top of the Segment Routing Talk from DENOG8 we showcase what multi vendor Traffic Enginneering options are available using Open Source Tools

The DENOG 8 Talk "Next-Generation Traffic Engineering with SPRING" introduced the building blocks of Segment Routing as a new MPLS signaling protocol. Traffic engineering capabilities were allready built into the protocol, but next to no implementations were present. After a short recap of the general SR/SPRING information we will show a demo implementation of a Traffic Engineering controller.

We build a showcase traffic Engineering Controller based on Open Source Tools: - Streaming Telemetry for real time Traffic insight into the network - BGP-LS into ExaBGP streaming into a redis storage - netconf calls for information enrichment - Web UI to display a topology view of the network - e.g. check real time traffic via Grafana integration - select a new network path for a given prefix via WEB-Ui - signal Traffic engineering Path to the network via BGP-LU from exaBGP

The Controller works against a test network running Arista and Juniper Devices.
