Olivier Dugeon
Senior Research Engineer, QoS And Network Control at Orange Labs
Brittany, France
Summary
🤩
Rockstar🎓
Top SchoolOlivier Dugeon is a senior research engineer based in Brittany, France with 11 years of professional experience focused on QoS and network control at Orange Labs. He holds advanced academic credentials in computer systems networking and telecommunications (PhD and HDR) and combines deep research insight with hands-on protocol engineering. Olivier is an active open-source contributor to major routing suites such as Quagga and FRRouting, where he implemented Traffic Engineering features, RFC-compliant IS-IS/OSPF enhancements, and a CSPF algorithm demonstration. His work bridges theory and production: he fixes subtle protocol bugs (e.g., Opaque LSA sync) while adding practical capabilities like TE link parameters and router capability support. Colleagues rely on him for complex control-plane solutions that improve traffic steering and MPLS behavior across carrier networks.

FRRouting/frr
Mar 2019 - Nov 2022
The FRRouting Protocol Suite
Role in this project:
Back-end Developer
Back-end DeveloperContributions:287 reviews, 19 commits, 150 PRs in 3 years 8 months
Contributions summary:Olivier primarily contributed to the FRRouting (FRR) Protocol Suite, focusing on enhancements and bug fixes within the IS-IS and MPLS-TE modules. Their work included resolving issues related to IS-IS-TE metric propagation and default TE metric assignment, ensuring the correct behavior of traffic engineering within the network. Additionally, they added a new command (`show sharp cspf`) and a corresponding topotest to the sharpd module, introducing and demonstrating the use of a Constraint Shortest Path First (CSPF) algorithm. Furthermore, the user modified the isisd module to disable MPLS table entries when SR is disabled.

Quagga/quagga
Nov 2014 - Apr 2016
Quagga Tracking repository - Master is at http://git.savannah.gnu.org/cgit/quagga.git
Role in this project:Back-end Developer
Back-end DeveloperContributions:32 commits in 1 year 5 months
Contributions summary:Olivier made significant contributions to the Quagga routing software, primarily focused on implementing and enhancing Traffic Engineering (TE) features. They addressed bugs in OSPF, specifically related to Opaque LSA synchronization, and added link parameter support to Zebra, enabling the propagation of TE information to routing daemons. Further contributions involved the implementation of RFC3630 and other RFCs to support the Traffic Engineering in IS-IS. They also contributed to implementing Router Capabilities support to OSPF.
