Abstract
A switch fabric system and network element based thereon include a N×M switch fabric with M Trail Termination Points (TTPs) each with N timeslots there through in a bidirectional manner, a first connection in the switch fabric, wherein the first connection includes a unidirectional asymmetric connection of X timeslots, wherein X<N, and a second connection in the switch fabric in an opposite direction as the first connection, wherein the second connection includes a unidirectional asymmetric connection of Y timeslots, wherein Y<N, and wherein at least one of the Y timeslots overlaps with one of the X timeslots on a same TTP of the M TTPs, wherein N, M, X, and Y each include an integer. A method includes establishing unidirectional asymmetric connections with overlapping portions therein as well as merging, splitting, and converting connections in-service and minimizing blocking probabilities.
