Centralized performance control for datacenter networks
An ideal datacenter network should allow operators to specify policy for resource allocation between users or applications, while providing several properties, including low median and tail latency, high utilization (throughput), and congestion (loss) avoidance. Current datacenter networks inherit …

Opportunistic Packet Forwarding for Proactive Transport in Datacenters
Proactive transport protocols in datacenters are designed to avoid congestion by regulating flow sending rates via credit allocation. However, when a new flow starts, it takes one Round-Trip Time (RTT) before credits can be assigned to the new flow. To avoid stalling flows, modern proactive …
