Thanks Alvaro! I coauthored a related paper that was published last year in the GreenNet workshop. This "*paper provides a holistic view of green TE using evolving SDN and SR-specific features without adding much additional computational tasks, and also considers SR segment processing overhead for energy efficiency*." Unfortunately we did not perform empirical analysis to provide PoC for the algorithms in the paper. The paper is available here: https://ieeexplore.ieee.org/abstract/document/9844091 Hesham On Tue, Jan 24, 2023, 7:55 AM Alvaro Retana <aretana.ietf@gmail.com> wrote: > On January 21, 2023 at 4:11:41 AM, Michael Welzl wrote: > > > ... > > > minimizing power consumption while maintaining QoS are in conflict. > > > Therefore, any solution will involve some kind of compromise between > the > > > two. > > > > > > … that’s just not true.
