Abstract

The present invention provides methods and systems for managing matrices of connections within digital switching fabrics. The methods and systems include means for defining one or more of sources and sinks in a matrix of connections as one or more of unidirectional connection termination points and novel unidirectional virtual connection points, where each of the unidirectional virtual connection points is a logical object that is maintained in software that defines connections between one or more of network resources and logical objects. The virtual connection points selectively act as origination points for one or more of other virtual connection points and termination points in a cross-connect; termination points for one or more of other virtual connection points and origination points in a cross-connect; origination points for a multicast set of connections; intermediate points within a cross-connect for the addition of new connections; selectors for two or more inputs; simultaneously as selectors for two or more inputs and as origination points for a multicast set of connections; one or more of bridges, selectors, and bridge/selectors in a protection application; one or more of origination points and termination points in a signaled network connection; local test access points; and/or remote test access points.
