ABSTRACT
The effects of data center traffic characteristics on data cen-
ter traffic engineering is not well understood. In particu-
lar, it is unclear how existing traffic engineering techniques
perform under various traffic patterns, namely how do the
computed routes differ from the optimal routes. Our study
reveals that existing traffic engineering techniques perform
15% to 20% worse than the optimal solution. We find that
these techniques suffer mainly due to their inability to uti-
lize global knowledge about flow characteristics and make
coordinated decision for scheduling flows.
To this end, we have developed MicroTE, a system that
