Abstract

Datacenter network switches share packet buffers among all ports to enhance throughput and reduce packet drops. However, declining buffer space per-port-per-bandwidth unit challenges buffer-sharing mechanisms, affecting performance. Recent studies, like ABM (SIGCOMM 2022), suggest hierarchical packet admission schemes to address this, but their complexity hinders efficiency. We propose CBM, a packet delay-based buffer sharing scheme that manages buffer space and controls queue drain rates using a single configurable parameter. Preliminary evaluation shows that CBM improves advanced transport protocol performance, such as PowerTCP, reducing Flow Completion Times (FCTs) by up to 45.07% compared with ABM.
