Guaranteed cell sequence in nonblocking multi-channel switching

The paper investigates multi-channel switching as a promising alternative to traditional single-channel switching where virtual paths established in a switch are between a single input channel and a single output channel. Building on a particular nonblocking condition for the flip networks, a multi-channel switching architecture that supports an arbitrary number of channel groups is formulated. In multi-channel switching, cells belonging to a single session can traverse multiple channels. The architecture proposed in the paper provides the time ordering integrity among those cells without employing any resequencing mechanism
