Abstract
An enhanced Dense Wave Division Multiplexing (DWDM) network is optimized through bundling subchannel traffic in DWDM channels at network nodes and “hubbing” the DWDM channels at nodes receiving a relatively higher volume of aggregate traffic than other nodes. The optimization can eliminate low rate links and supporting network equipment. The bundling and hubbing may also be used independently from one another. The DWDM network may be enhanced with SONET, SDH, Ethernet, ATM, or other technology. The DWDM network may be a BLSR, UPSR, point-to-point, mesh, or other network configuration.
