Overview of the Work Programme
The work program consists of 6 research work packages (WP 2,4,5,6,7, and 8), one management work package (WP1), and one dedicated to dissemination (WP3), which includes interaction with standardization and regulatory bodies.
WP1 - Management of the project and communication with EC
WP1 will coordinate the management and reporting activities of the IP through a Coordinator, a project manager, technical leaders, an administrator, in addition to a supervisory board, a management committee and a technical committee.
WP2 - Architecture design and modelling
WP2 will conduct all architectural modeling including overall design, network resilience, techno- economic studies, power consumption modeling and traffic and service modeling, and thus will feed all other technical work packages (WP4, 5, 6, 7 and 8). Work packages 4, 5, 6 and 7 will progress the research in the access, core and backbone parts of the network.
WP3 - Policies, Standardisations and Regulations, Impact and Dissemination
Project dissemination will be carried out in WP3. Besides academic publications, two workshops and other public dissemination, DISCUS aims at bringing a strong impact to standardization and regulation activities. In particular DISCUS aims at steering decisions of the national and European telecoms regulator on the use of the newly deployed fibre infrastructure.
WP4 - Long reach access network and wireless integration
WP4 will look into the details of the Long-reach access part of the network, considering study and deployment of novel LR-PON protocols, integration with the wireless access network, technical management of the PON and optimized deployment strategy. Study and development of physical layer component technologies to improve the long-reach access network will be dealt with in WP5.
WP5 - LR-PON critical physical hardware implementation
The main objective of this Work Package is the realisation of the critical component technologies required for the proposed network architecture and are not yet available today. This includes development of novel tuneable filters and sources for dynamic bandwidth allocation in the wavelength in addition to the time domain; systems with higher dynamic range to allow a more flexible layout of the distribution network; higher-rate, low cost PON systems (40Gb/s); and an integration of coherent systems into the long-reach access. The control of tuneable devices will be closely developed with the protocol in WP4 and the control plane in WP6.
WP6 - Metro/core node design
WP6 will develop the architecture and technology for the metro/core node. In addition to architectural design that will follow the studies initiated in WP2, this work package will progress the development of two main node elements. One is the development of the technology for ultralow loss, high port count fibre switches: DISCUS will look at the development of large switching matrices and 3-stage switching architectures to enable switches with over 12000 ports. The second is the development of a highly integrated control plane for the metro/core node, able to enable wavelength services on demand, and efficient layer2 and 3 packet and flow switching.
WP7 - Backbone network design
WP7 will look at the backbone network, considering overall design, control plane and resilience. One important task will be the study and optimization of “optical islands”, which define the boundary of the flat optical core, due to the physical impairment of the optical signal. The backbone control plane will be closely developed with that of the metro/core node in WP6.
WP8 - Critical systems test and verification
All the developed hardware and software components will finally be tested and verified in WP8 in an integrated testbed experiment.
