Figure 1 shows a three-stage Clos network with a system of overflow links in the first stage of the network.
Therefore, for a three-stage Clos network without overflow links, we can write
The 'Subnet Manager' - the software responsible for pre-calculating traffic paths within a subnet, - is currently limited to dealing with simple, regular topologies (such as Clos networks or hypercubes).
It is non-blocking for unicast and multicast traffic and can be configured in multi-stage Clos networks to deliver multiple terabit performance.
