Abstract
In recent years, several techniques have been suggested
for routing and traffic engineering in data centers. How-
ever, not much is known about how these techniques per-
form relative to each other under realistic data center traf-
fic patterns. Our preliminary study reveals that existing
techniques can only achieve 80% to 85% of the ideal so-
lution in terms of the number of bytes delivered. We find
that these techniques suffer due to their inability to utilize
global knowledge of the properties of traffic flows and
their inability to make coordinated decision for schedul-
ing flows at fine time-scales. Even recent traffic engi-
