Abstract
A ring-based switch has nodes with a link management logic having forward and reverse link outputs couplable to other nodes, forward and reverse link inputs adapted couplable to other nodes, and memory coupled to the link management logic. The link management logic has a first mode where packet bursts are received through the forward link input and transmitted on its forward link output. The link management logic has a second mode where packet bursts are received through the forward link input and transmitted on its reverse link output; and a third mode where packet bursts are received through the reverse link input and transmitted on its forward link output. The node transmits test packets over the forward link output and, if no acknowledgment is received over the reverse link input within a predetermined test-time interval, the link management logic configures in the second mode.
