In Sigmetrics 2022 the paper "*Cerberus: The Power of Choices in Datacenter Topology Design*" was published [ https://people.csail.mit.edu/ghobadi/papers/cerberus_sigmetrics_2022.pdf].
"This paper uncovered a potential of serving datacenter traffic with the switch technology that best matches its structure. By tapping into this potential, we developed a solution, Cerberus, which we showed to significantly improve throughput" Perhaps Cerberus is best suited for ML. Comments?
