A multi-interface point-to-point switching system, including a plurality of IO ports coupled to a plurality of respective devices, a switching fabric, a controller that determines the fixed, low latency signal path for each connection and commands the switching fabric to establish the determined signal path for each connection. According to one aspect of the invention, the switching fabric includes a plurality of discrete switch modules, at least selected ones of which are hot-swappable with permission of the controller. According to another aspect of the present invention, a switching fabric that selectively delivers each of a plurality of different signals from a selected one of the IO ports coupled to a sending one of the devices to another selected one of the IO ports coupled to a receiving one of the devices, to thereby establish respective connections between the sending and receiving devices, wherein the switching fabric provides a fixed, low latency signal path for each connection between a sending and receiving device for the duration of that connection, whereby the latency of that connection is deterministic and predictable, and a data content of the signal delivered via that connection is not analyzed by the switching fabric, whereby the switching fabric operates in a content-independent manner.
