Abstract

   To ensure an efficient data transport, meeting the requirements
   requested by today's IP-services the control and management of DWDM
   interfaces are a precondition for enhanced multilayer networking and
   for a further automation of network provisioning and operation.  This
   document describes use cases, requirements and solutions for the
   control and management of optical interfaces parameters according to
   different types of single channel DWDM interfaces.  The focus is on
   automating the network provisioning process irrespective on how it is
   triggered i.e. by EMS, NMS or GMPLS.  This document covers management
   as well as control plane considerations in different management cases
   of single channel DWDM interfaces.  The purpose is to identify the
   necessary information elements and processes to be used by control or
   management systems for further processing.
