Management issues in transparent optical networks

All-optical networks (AONs) are emerging as a promising technology for very high data rate communications, flexible switching and broadband application support. They contain only optical components and vary to a large extent from traditional optical networks. Due to this specific variation, AONs have unique features and requirements in terms of security and quality of service (QoS) that require a very targeted approach in terms of network management. The paper discusses management issues and requirements that arise from using optical components in communication systems. It then proposes a management framework for the realization of an appropriate network management system (NMS) that can meet the challenges posed by AONs.
