Data center fabrics are built today using spine and leaf fabrics, lots of fiber, and a lot of routers. There has been a lot of research in all-optical solutions to replace current designs with something different; MegaSwitch is a recent paper that illustrates the research, and potentially a future trend, in data center design. The basic idea is this: give every host its own fiber in a ring that reaches to every other host. Then use optical multiplexers to pull off the signal from each ring any particular host needs in order to provide a switchable set of connections in near real time. The figure below will be used to explain.
In the illustration, there are four hosts, each of which is connected to an electrical switch (EWS). The EWS, in turn, connects to an optical switch (OWS). The OWS channels the outbound (transmitted) traffic from each host onto a single ring, where it is carried to every other OWS in the network. The optical signal is terminated at the hop before the transmitter to prevent any loops from forming (so A’s optical signal is terminated at D, for instance, assuming the ring runs clockwise in the diagram).
