Incast variable
WebWhile modern datacenter topologies provide high bisection bandwidth to support all-to-all traffic, incast is fundamentally a many-to-one traffic pattern, and therefore, requires deep buffers or high bandwidth at the network edge. We propose Superways, a heterogeneous datacenter topology that provides higher bandwidth for some servers to absorb ...
