Abstract

To isolate service queues in data centers, recent solutions assume Explicit Congestion Notification (ECN)-enabled end-hosts. However, this assumption is not valid in multi-tenant environments where tenants own the network stack. This letter presents BarberQ, a multi-queue management scheme that isolates service queues without dependency on transport protocols. At the heart of BarberQ lies dynamic buffer sharing through packet eviction. Our benchmark results demonstrate that BarberQ not only achieves minimum guarantees and work conservation, but also provides low latency.
