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 MPLS router (IP/TDM/wavelength) from Furukawa Electric, and optical cross connect (wavelength/fiber) from Mitsubishi Electric. All the equipment runs a GMPLS-compliant routing protocol (GMPLS OSPF-TE). Each active component advertises the function and the layer that it handles. This allows all GMPLS equipment to recognize the layers handled by other equipment.
The interworking experiment will be demonstrated at this week’s MPLS2003 exhibition in Washington, D.C.
