Definition: switch fabric
(1) The interconnect architecture used by a switching device, which redirects the data coming in on one of its ports out to another of its ports. The word "fabric" comes from the resulting criss-crossed lines when all the inputs on a switch with hundreds of ports are connected to all possible outputs.
(2) The combination of interconnected switches used throughout a campus or large geographic area, which collectively provide a routing infrastructure.
