Description and expertise of the organisation:
AGH University of Science and Technology, founded in 1919, is ranked as one of top Polish universities involved in research and education in information technologies.

The Department of Telecommunications is a part of the Faculty of Electrical Engineering, Automatics, Computer Science and Electronics. The Department staff consists of more than 40 people (including 5 full professors); about 20 Ph. D. students are affiliated at the Department.

Since 1996 the Department of Telecommunications has been involved in various European projects including 4th, 5th, 6th, and 7th Framework Programmes. It was also active in developing strategies and network planning for major Polish telecommunications operators. Professors and researchers of the Department served as consultants for network operators, equipment vendors, and regulatory bodies in Poland and abroad as well as were invited to reviewing European projects. Department members have been active in professional societies, organizing international and national conferences (including IEEE and IFIP events) and research workshops as well as holding important editorial positions in leading journals and magazines, such as IEEE Communications Magazine, IEEE Transactions on Communications, Computer Communications, or Security and Communication Networks.

Major research areas of the Department of Telecommunications include broad range of modern topics related to wireless and optical networks, security of telecommunication systems, multimedia services and others.

The optical networking group of Department of Telecommunications is interested in joining PIANO+ programme, especially it is interested in continuing research in the area of high data rate access networks, network reliability and survivability, overlay networking, optical networks for FTTP traffic aggregation. The group has proved the innovation of its research activities with the numerous publications at the most recognised conferences and in the most notable journals.

The optical networking group of Department of Telecommunications has got important experience in international research projects, cooperating with major European telecom operators and research centres. The list of the selected projects focused on optical networking the group has been involved follows.

• Euro-NF: Anticipating the Network of the Future - From Theory to Design, 2008-2010

• SmoothIT: Simple Economic Management Approaches of Overlay Traffic in Heterogeneous Internet Topologies, 2008-2010

• BONE: Building the Future Optical Network in Europe: The e-Photon/ONe Network, 2008-2010

• NOBEL 2: Next generation Optical network for Broadband European Leadership phase 2, Integrated Project, 2006-2008

• Euro-FGI: Design and Engineering of the Future Generation Internet - Towards convergent multi-service networks, 2006-2008

• NOBEL 1: Next generation optical network for Broadband in Europe, Integrated Project, 2004-2006

• Euro-NGI: Design and Engineering of the Next Generation Internet - Towards Convergent Multi-service Networks, 2003-2006

• E-PHOTON/One+, Optical networks: Towards bandwidth manageability and cost efficiency, Networks of Excellence, 2006 — 2008

• E-PHOTON/ONe Optical networks: Towards bandwidth manageability and cost efficiency, Networks of Excellence, 2004 — 2006

Optical networking group of AGH Department of Telecommunications has been contributing mainly to the research area of designing and performance monitoring of metro and core optical networks, including QoS provisioning, resilience assurance, techno-economic studies. Our experience can be used in the area of optical access networks.


Research interests / Project ideas
The optical networking group of AGH Department of Telecommunications is interested in the project of PIANO+ programme that aims at specification, verification and validation of new systems and architectures related to advanced optical access networks. Our focus is on CWDM PON technology, but GPON/EPON is still relevant. The group would like to contribute with a set of mechanisms that will allow autonomic reconfiguration of the access network at different (photonic, optical, electrical) layers subject to: changing traffic distribution resulting from end-user and business needs, network, node, component failures, as well as changes in a network environment (for example changed power supply source).

Optical access networks (GPON, EPON, CWDM PON) are expected to face dynamic changes in traffic flow distribution between residential and business areas – self adaptation of a network to current traffic flow would assure efficient resource utilization. Novel adaptive power supply solution is the next area of interest. Remote optical units facing power supply failure need to switch to battery mode and self reconfigure to optimize network and service availability. All major optical network elements (nodes) are expected autonomously apply the proper traffic engineering and resource management tools, and apply appropriate recovery procedures in the case of node/component failure. They will take decisions that allow for optimal or near-optimal use of available resources and lead to better performance of the network seen as a whole. The next issue the AGH optical group would like to address is self organization of an aggregation domain of optical access networks. Architectural aspects of a network interconnecting high speed (especially CWDM PONs) optical access are in the research area of the group.
The optical networking group of AGH Department of Telecommunications is ready to contribute to autonomous optical access network solutions at the architectural level. Close and effective cooperation with partner or partners focused on photonic issues is necessary to meet PIANO+ aims and assure feasibility of proposed solutions.
