This paper proposes a layered network architecture for optical transport networks and the concept of optical path network management. First, the WDM (wavelength division multiplex) based optical path network concept and realization techniques such as the WP (wavelength path) and the VWP (virtual WP) are presented. Second, a new layered architecture for WDM based transport networks is proposed. The proposed network architecture retains maximum commonality with existing B-ISDN networks. Finally, optical transport network management functions such as configuration, performance and fault management, are discussed
