FYI: Green Routing protocols
by Vesna Manojlovic 03 Apr '24

03 Apr '24

FYI: There are many papers about Green Routing protocols. [2],[3] This paper [1] is an example from Prof Simon Romano which presents an "extension of the OSPF protocol to optimize the overall energy consumption of the network." The algorithm devised in this paper represents an engineering approach to the solution of the well known (though still open) issue of dynamic network topology adaptation to improve energy efficiency. For the GOSPF proposal there is running code available for people who want to play with it (https://wpage.unina.it/spromano/gospf/). It was based on the Quagga suite.It would need some tweaking in order to work with the current releases of the software. [1] GOSPF: An energy efficient implementation of the OSPF routing protocol https://arxiv.org/abs/2207.00035 (via E-impact mailing list https://www.ietf.org/mailman/listinfo/e-impact) + [2] Carbon-Aware Global Routing in Path-Aware Networks https://netsec.ethz.ch/publications/papers/green_routing2023.pdf [3] Exploring the Benefits of Carbon-Aware Routing : https://dl.acm.org/doi/10.1145/3629165 ^^^ this will be presented at RIPE88 !!
