Cel
MOON is a project in the scope of the second ACTS call and aims at the development of a framework for the management of the photonic layer of the future pan-European transport network. Key functionalities will be implemented in a field demonstrator network, called MOONET. Management of wavelength division multiplexing (WDM) optical cross connects and WDM transmission links, spanning some hundreds of kilometres using optical in-line amplifiers, will be included.
The objectives of the project are:
To identify network elements of the optical network, such as optical cross connects (OXCs), optical amplifiers and optical terminal multiplexers (OTMX), which need to be addressed in the context of network management and operation and maintenance.
To examine the applicability of concepts for existing transport networks regarding operation, administration and maintenance (OAM) and management of the network by a telecommunication management network (TMN).
To adapt and develop OAM, TMN and network protection concepts for optical transport networks including protocols, managed objects and their defined attributes.
To demonstrate and validate these concepts in a field trial network, called MOONET.
In the first project period, the requirements for the network management system of optical networks and the TMN requirements for the optical network elements have been defined. Drafts of the underlying TMN concepts and the management information model have been generated.
The configuration of the field trial will give a sound basis for the test of the functionality of a managed network. Moreover, its structure will allow for the introduction of a sufficient variety of induced failures for a critical evaluation of the network functionalities.
As an example the failure of a fibre link connecting two OXC's can be simulated, in order to test the fault notification services supplied by the fault management functional area of the management system. Failure scenarios include the failure of an OXC, of optical amplifiers, and the occurrence of excessive signal attenuation. Examples for configuration management will include the routing process and adjustment of the optical power level.
Easy access will be possible for applications because SDH equipment is connected, which permits connection to the public transport network. For both configuration and fault management functional areas, interworking between the corresponding features of fault and configuration management of SDH access equipment will be investigated.
Expected Impact
Contributions will be made to standardisation bodies, in particular ITU-T and ETSI, as well as to concertation activities within ACTS. In the other direction, substantial input about network management is expected from the ACTS concertation chain NIM, "Interoperability of network management systems".
Photonic overlay networks should bring cost effective transport of large data streams. Network management will enhance their effectiveness. The proposed work will form a further important step towards the future optical transport network in the core area of the European integrated broadband communications network (IBCN).
Main contributions to the programme objectives:
Main deliverables
Developed a framework for the management of the photonic layer in the future pan-European transport network, including FDM cross-connects and transmission.
Contribution to the programme
Cost-effective transport of large data streams, as required in future photonic networks.
Technical Approach
The all-optical transport network is decomposed into three layers located between the regenerator section layer of its client (e.g. SDH) and the physical media layer. The characteristic information and the transport processing functions for each layer is to be defined to ensure proper OAM functionality. The OAM functionality is supported by an overhead channel using an additional frequency added to each link.
For the management of optical transmission (amplifier) sections a supervisory channel will be implemented using WDM techniques. An optical 1R regenerator consists of an in-line amplifier and, where necessary, a dispersion compensating module. A single out-of-band signal (with respect to the gain profile of the amplifiers) will be used as supervisory channel. Such a solution guarantees a clear separation between OAM and customer information streams. The supervisory signal will be terminated at each regenerator site, dropped in front of the amplifier device, converted, processed and optically re-inserted again after the amplifier device. At the OXC nodes the supervisory channel is finally terminated and a suitable interface towards network management is provided.
Network providers expect their system suppliers to deliver system solutions rather than only network components. Furthermore, they expect to get a solution compatible to their existing TMN applications. For this purpose mediation devices are used in many applications. These mediation devices provide a standardised interface (Q3) to the TMN. However, there may be different interfaces to the system components (network elements) of the application. One of the MOONET OXCs will have a Q3-interface, while a mediation device will be implemented for connecting the other two OXCs to the TMN.
Summary of Trial
The MOONET field trial will be based on the WDM links and the OXC of the ACTS project PHOTON. The PHOTON demonstrator network PHOTONET, configured as a star network, will be extended within MOON:
In a first step two additional OXCs will be supplied as background equipment by different partners. The OXCs will be adapted to the network and upgraded to provide a network management interface. These two OXCs will be integrated with the management application based on a TMN-OS and the manageable optical in-line amplifiers.
Finally, the two node supplement will be integrated with the existing network and the enhanced OXC of PHOTON and MOONET will enter its operating phase. At this time MOONET will be a fully meshed network with three OXCs and two optical terminal multiplexers.
Key Issues
Key issues are the management of optical cross connects and of optical amplifiers. The definition of an appropriate management information model for the managed objects of these network elements is very important, in order to achieve a management solution which fits smoothly into the existing management infrastructure of electrical networks.
The main focus is on fault and configuration management. The optical nature of the signals will impact most on the implementation of these management functions. The technical challenge to meet is twofold: to restrict the significant and necessary parameters for presentation to the network management level, and to get as much information as possible from the optical signals without having bit-level access to their payload.
