pHost – Distributed Near-Optimal Datacenter Transport Over Commodity Network Fabric

The importance of minimizing flow completion times (FCT) in datacenters has led to a growing literature on new network transport designs. Of particular note is pFabric, a protocol that achieves near-optimal FCTs. However, pFabric’s performance comes at the cost of generality, since pFabric requires specialized hardware that embeds a specific scheduling policy within the network […]
