Packet delay is a key indicator of network health. Traditional packet delays focus on coarse-grained per-hop or end-to-end delays. However, this paper focuses on Intra-Flow Packet Delay (IFPD). It is ...

Clos-based networks including Fat-tree and VL2 are being built in data centers, but existing per-flow based routing causes low network utilization and long latency tail. In this paper, by studying the ...
