Micro Load Balancing in Data Centers with DRILL

The trend towards simple data center network fabric strips most
network functionality, including load balancing capabilities, out of
the network core and pushes them to the edge. We investigate a
different direction of incorporating minimal load balancing
intelligence into the network fabric and show that this slightly
smarter fabric significantly enhances performance. We provide a very
simple in-network load balancing scheduling algorithm called DRILL
which is purely local to each switch. DRILL leverages local load
sensing and randomization concepts to distribute load among multiple
paths. Through simulation, we show that this simple approach
outperforms CONGA, a recent global edge-based load balancing scheme
for data centers. We also formally prove the switch-level stability
and throughput-efficiency of DRILL’s scheduling algorithm.
