Data Center Network TrendsThe Problem
Flat Topologies No Oversubscription Large machine-machine data
flows (e.g. VM Migration, Hadoop)
75% of Traffic is East-West Low latency required Scale to 100G & beyond
75 % Traffic
Data Center Aggregation
Places huge demand on Cluster Aggregation layer • Doesn’t scale well• Expensive in $, power,
space, & adds latency• Replace or Upgrade
regularly
