Abstract: By extending MPAS technology to subcarrier domain, a novel broadband op-tical network scheme to fuse TV networks and optical internet with high efficiency-multi-protocol subcarrier/lambda label switching networks based on subcarrier label and switching interfaces, is proposed. By utilizing new compound label and basing on two-layer subcar-rier/lambda switching frame, a multi-layer dynamic Traffic Engineering(TE) and a flexible QoS guarantee are realized, which use wavelengths in a economical way. The structure of two-layer label switching router and its performance are analyzed and some key problems facing by this scheme and related solutions are presented. -
