Abstract: OBS(Optical Burst Switching) is a transitional solution from electrical switch to packet switch, G-LOBS(GMPLS-based Optical Burst Switching Network) is a combination of MPLS(Multi-Protocol I_abcl Switching) technology and OBS technology,which is an effective solution for the evolvement of present optical network to optical internet. The idea of building a uniform G-LOBS network simulator was put forward. The signaling module of RSVP-TE(Resource Reservation Protocol-Traffic Engineering) was designed, and the simulation analysis of RSVP-TE by OPNET was done.
