Abstract
This paper presents a detailed examination of a
novel data center network (DCN) that can satisfy the high capacity
and low latency requirements of modern cloud computing
applications. This reconfigurable architecture called AgileDCN
uses fast-switching optical components with a centralized control
function and workload scheduler. By providing a highly flexible
network fabric between racks that can be reconfigured to provide
all-optical paths, network efficiency can be improved significantly.
The simulation results show that the AgileDCN network can
deliver TCP flow completion times significantly shorter than an
equivalent electronic leaf-spine topology at high (70%) loads.
