Abstract
In a communications network, which may be a broadband optical network, a packet is transmitted from a source node to a destination node on a looped signal path. A return signal, which may function as an acknowledgement of the original signal, is transmitted back to the source node from the destination node in the time slot which was occupied by the original packet.
