A networking device that typically lives at the top of a rack and 
performs routing (i.e. it acts as the default gateway) for hardware 
devices in that rack is called a "top of rack switch" or TOR [1]. When 
the phrase "top of rack switch control" is used, it means that Neutron's 
ML2 plugin can control that TOR switch directly via the switch's native 
management interfaces.
