Optical network management

Multiwavelength technology is expected to play a vital role in the next-generation transport networks. The enormous intrinsic bandwidth of the fiber and the promise of recent advances in wavelength rearrangement techniques offer exciting possibilities for novel applications in both the backbone and access networks. Despite the advances in physical layer technologies, considerable effort is still required in the operation and network management areas for the practical deployment of multiwavelength optical networks. In this tutorial, we will begin with an introduction to basic network management concepts. We will then describe management and control needs specific to reconfigurable WDM nets. Topics to be covered include: telecommunications management network (TMN) principles; management protocols; information modeling; embedded management channel; alarm surveillance; fault correlation; connection management; OA&M features to support survivable optical network architectures; and integration of optical network management with ATM/SONET network management
