Abstract: As overlay networks in the data center become more common place,
everyone is trying to build the best possible underlay using CLOS
fabrics. A key issue with large 5-stage CLOS fabrics are the
provisioning and management. This presentation proposes a method to
simply the management of a 5-stage CLOS fabric by collapsing three
stages into a logical entity called a vSpine. By creating a
multi-stage CLOS using a vSpine in the middle stage, it effectively
reduces the operational overhead of a five-stage CLOS down to a
three-stage CLOS, but with the benefit of having the scale of a five-
state CLOS.
