We present the design, implementation, and evaluation of B4, a private WAN connecting
Google's data centers across the planet. B4 has a number of unique characteristics: i) …

Although there is tremendous interest in designing improved networks for data centers, very
little is known about the network-level traffic characteristics of data centers today. In this …

Today's data centers offer tremendous aggregate bandwidth to clusters of tens of thousands
of machines. However, because of limited port densities in even the highest-end switches …

To be agile and cost effective, data centers should allow dynamic resource allocation across
large server pools. In particular, the data center network should enable any server to be …
