On Next-Generation Metro and Access Networks

  1. 1. 1 www.eurosouthkorea-ict.org - info@eurosouthkorea-ict.org On Next-Generation Metro and Access Networks Kyeong Soo (Joseph) Kim Senior Lecturer Institute of Advanced Telecommunications (IAT) School of Engineering Swansea University Wales, UK An event organised by the European Commission (DG INFSO) & the South Korean Ministry of Knowledge Economy (MKE) December 1-2, 2008 Radisson SAS Royal Hotel Brussels, Belgium 2nd EU-Korea Cooperation Forum on ICT Research www.eurosouthkorea-ict.org - info@eurosouthkorea-ict.org Institute of Advanced Telecommunications (IAT), Swansea University A research-centred institute focusing on all aspects of telecommunication technologies. 13 academics and core research assistants with proven expertise and international profile Specialized and state-of-the-art labs with capital assets valued at over £4M Photonics research group DWDM transmission Advanced modulation techniques for 100+ Gbit/s Fiber optical parametric amplifiers (OPAs) Components and networks research Optical regeneration, wavelength conversion, and WDM sources Advanced Erbium-doped amplifier (EDWA) Organisation Profile & Activities
  2. 2. 2 www.eurosouthkorea-ict.org - info@eurosouthkorea-ict.org Wireless research group Signal processing for communications Smart antennas/MIMO, adaptive/iterative receiver design, space-time coding Digital communications Adaptive coding & modulation, multiple access (OFDM, CDMA, MC-CDMA) RF & Microwaves Systems e-Health, intelligent transportation systems Networks Research Group Wireless networking Mesh/ad-hoc/sensor networks, radio resource management Access & metropolitan area networks WiMAX, TDM/WDM PONs, hybrid optical-wireless networks Network security & QoS Internet security, multi-channel scheduling Organisation Profile & Activities www.eurosouthkorea-ict.org - info@eurosouthkorea-ict.org Current Network Limitations Bandwidth-hungry services (e.g., VOD, IPTV) Increase the amount of network infrastructure Increase the network energy consumption Increase the data-driven network crashes Due to: Unbalance in capacity between core and access Mismatch between service/usage models and network infrastructure Large number of power-hungry and error-prone electrical components/systems
  3. 3. 3 www.eurosouthkorea-ict.org - info@eurosouthkorea-ict.org Paradigm Shift in Optical Networking Changes in network architecture Performance →→→→ Energy Efficiency driven design Static →→→→ Dynamic, Reconfigurable network Dedicated →→→→ Shared resources Separate, complicated →→→→ Integrated, Simplified management layers/interfaces Unbalanced →→→→ Balanced bandwidth link utilization Enabled by rapid development in core technologies Burst-mode communications Optical packet/burst/flow switching Fast tunable optical components www.eurosouthkorea-ict.org - info@eurosouthkorea-ict.org Issues in Next-Generation Metro and Access Networks Optical-wireless convergence Mesh (multi-hop) networking and 4G will be key technologies Metro-access integration Common network architecture for both Strategy for upgrading existing optical infrastructure (e.g., SONET ring & TDM-PON) By introduction of WDM? Through either WDM or hybrid TDM/WDM (with tunable components) By extension of TDM? Through longer-reach, higher-speed, and higher-split TDM-PONs

Wi-Fi Cities Need good expertise in WiMAX (WiBro) base station in studying interfacing between WiMAX and WLAN mesh. MiSON Ongoing collaboration with BT KT and other network operators could collaborate with BT through this project.
