摘要
光突发交换技术(OBS,Optical Burst Switching)是电路交换到分组交换的过渡技术,G-LOBS网络是通用多协议标记交换(GMPLS,Generalized Multi-Protocol Label Switching)技术和OBS技术结合的产物,后者是将现有光网络技术向光因特网过渡的有效途径。提出了基于OPNET软件的G-LOBS通用仿真平台的设计,设计出了基于流量工程的资源预留(RSVP-TE,Resource Reservation Protocol-Traffic Engineering)信令模块,并用OPNET软件对RSVP-TE协议进行了仿真分析。
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 Label Switching) techno-logy and OBS technology,which is an effective solution for the evolvement of present optical network to optical inter-net.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 OP-NET was done.
