Aeolus: A Building Block for Proactive Transport in Datacenters
As datacenter network bandwidth keeps growing, proactive transport becomes attractive, where bandwidth is proactively allocated as “credits” to senders who then can send “scheduled packets” at a right rate to ensure high link utilization, low latency, and zero packet loss. While promising, a fundamental challenge is that proactive transport requires at least one-RTT for credits to be computed. In this talk, I will introduce Aeolus, a solution focusing on “pre-credit” packet transmission as a building block for proactive transports. I will also discuss a series of challenges to deploy proactive transports in production environments.
