The managed all-optical WDM transport network with the all- optical cross-connects is offering not only the high bandwidth, which can be shared between arbitrary clients accessing the network, by static allocation of the trails (also denoted as optical paths) or the virtual sub-networks, but also the service to perform reconfiguration of such virtual sub-networks and to reassign the capacity according to the demands and services required from the client, by the management actions. To fulfill the management task of providing the optical path, which is characterized by a set of optical parameters in the optical domain, the optical network management system must act upon the requirements of the different clients. This imposes that these requirements have their representation in the optical domain and vice versa. In this article we are investigating the possible approaches to WDM network management, first starting from the assumption that the capacity in the network can be arbitrarily shared between different transparent optical paths, and then introducing the analogous transmission parameters related to the transmission equipment and media which restrict this capability and make the management of the optical path dependent on the different types of the clients and different utilization of the capacity in the network. It is shown how those parameters are to be assigned to the different layers in the proposed layered architecture model of the optical network. This model is also discussed from the view point of the management integration and the optical QoS parameters mapping to the client QoS parameters are proposed.
