NTT, NEC, Furukawa Electric, and Mitsubishi Electric have successfully tested interworking between an MPLS network and a GMPLS photonic network. The trial verified cooperation between GMPLS routing and signaling technologies and demonstrated that a GMPLS communication path could be set up based on routing information from the MPLS network The work was conducted by the jointly operated Photonic Internet Lab. The GMPLS domain consists of a photonic MPLS router (IP/wavelength) from NTT, a digital cross connect (TDM/wavelength) from NEC, a GMPLS supported...
