Matrix-switch meaning

A switch comprising an array of internal buses or circuits laid out in a grid of rows and columns so that connections can be set up anywhere the circuits intersect, and a path can be established between any input port and any output port.There are physical matrixes (with metallic contacts) such as voice crossbar switches, and logical matrixes used in packet switches. A matrix switch can provide full bandwidth to multiple, simultaneous transmissions on a port-to-port, point-to-point basis. If there are congestion issues in a matrix switch, it may have the ability to subdivide its capacity, with the buses becoming shared buses through a process of time division multiplexing (TDM). See also bus, circuit, crossbar, cutthrough switch, LAN switch, port, shared bus switch, switch, and TDM.
