Hello community, I’m Ph. D. Student at University de Liège, Belgium, and I’m conducting a survey as part of my researches on Segment Routing (SR) traffic engineering practices among network operators. We have a technique, called ArEST, allowing us to discriminate SR-MPLS and regular MPLS traffic. See https://orbi.uliege.be/bitstream/2268/337150/1/paper.pdf and our Git https://gitlab.uliege.be/segment-routing. If you are involved in the management of SR in your network, I would greatly appreciate your input. The survey should take no more than 5 minutes to complete. Link to the survey<https://docs.google.com/forms/d/e/1FAIpQLSc0vz9hX5VF_Ii2bprgC1neZwVnaA5tGS3fcoVI2Jv_jPnq6g/viewform?usp=sharing&ouid=117740394913700139682> Best regards, Florian Dekinder Université de Liège
