1. A method of flowing traffic through an enhanced Dense Wave Division Multiplexing (DWDM) network, the method comprising:
bundling subchannel traffic in a DWDM channel to forward from a first node to a second node in a DWDM network if the subchannel traffic volume is above a first threshold; and
if aggregate traffic volume in DWDM channels received by the second node is below a second threshold, routing the subchannel traffic in the DWDM channels from the second node to a third node in the DWDM network receiving more aggregate traffic in DWDM channels than the second node to flow the traffic through the DWDM network.
