Fat-FREE Topologies
Ankit Singla · 2016
With the growing size of data center networks, full-bandwidth connectivity between all pairs of servers is becoming difficult and expensive to scale. Thus, numerous recent topology proposals incorporate reconfigurable wireless and optical connectivity, allowing the topology to adapt to the traffic demands --- only servers that require bandwidth at any given time receive such dynamic connections. Implicitly, this work has suggested that statically wired topologies are fundamentally inflexible, and would need to be built at full capacity to handle unpredictably skewed traffic.
