  1. Computer Networking Research at Karlstad University Anna Brunström

  2. Research Organization • Dept. of Computer Science, Research Groups • DISCO – Distributed Systems and Communications Group • PriSec – Privacy and Security Group • Multidisciplinary University Platforms • CMIT • Communication: Media and information technology • HumanIT • Human value of IT • Research on mobile communication, multimedia

  3. DISCO: People • Research Manager • Assoc. Prof. Anna Brunström • Ph.D. Students • Stefan Alfredsson • Katarina Asplund, • Johan Garcia • Karl-Johan Grinnemo (Tieto Enator) • Hannes Persson • Annika Wennström • Project Employee • Torbjörn Andersson

  4. DISCO: Projects • SCTP for soft real-time applications • Funding/Partners • Tieto Enator AB (Karl-Johan Grinnemo) • Continuation of 4 year cooperation • Part of CMIT platform • Consequences of SIGTRAN on transport performance • Performance of M3UA Failover Mechanisms • See presentation by Karl-Johan Grinnemo • General performance evaluation of SCTP • Partial Reliability in SCTP • Builds on previous work on partial reliability: PRTP, PRTP-ECN, Robust JPEG coder

  5. DISCO: Projects cont. • Protocol support for mobile environments • Funding/Partners • Telia Mobile AB (Jan Gustafsson, Jonas Eriksson) • Dr. Juan Rendon, UPF, Spain • Part of CMIT platform • Measurements of TCP over GPRS • GPRS testbed • Real nodes and protocol implementations • Emulated radio environment • See presentation by Annika Wennström

  6. DISCO: Projects cont. • Wireless IP • Funding/Partners • SSF • Uppsala University (Anders Ahlén, Mikael Sternad) • Chalmer (Arne Svensson, Tony Ottosson, Mats Viberg) • Saverio Mascolo, Bari, Italy, Torbjörn Ekman, Unik, Norway, Ericsson, NERA • A flexible, low-cost general packet data system allowing wide area coverage and high mobility (vehicular velocities) • 100 Mbit/s Ethernet, high spectral efficiency, QoS and fairness • Leads to an extreme system based on adaptive resource allocation

  7. DISCO: Projects cont. • Providing Optimum Capacity and Flexible Quality of Service in Packet-based Wireless Systems Using Scheduling and Soft Information • Funding/Partners • Vinnova • Uppsala University (Anders Ahlén, Mikael Sternad) • Chalmer (Tony Ottosson) • Related to Wireless IP project • Develop means to propagate soft information from the physical layer to the application • JPEG 2000 decoder that utalizes soft information • TCP-L, protocol that lets biterrors through • Develop efficient scheduling algorithms among multiple access points

  8. DISCO: Projects cont. • EU FP6 projects • WINNER Wireless World Initiative New Radio • Integrated Project • Wireless IP partner with Chalmers as main contact • Coordinator: Dr. Werner Mohr, Siemens AG • NEWCOM Network of Excellence in Wireless Communications • Network of Excellence • Coordinator: Prof. Sergio Benedetto, Istituto Superiore Mario Boella, Italy

  9. DISCO: Projects cont. • Other Activities • Transport Layer Loss Differentiation and Loss Notification • Distinguish the cause of a packet loss • Inform transport sender of cause: explicitly or implicitly • See presentation by Johan Garcia • Measurement Techniques • Impact of the position for packet loss • Time-driven versus data-driven biterrors

  10. PriSec: People • Research Manager • Prof. Simone Fischer Hübner • Researcher • Dr. Thijs Holleboom • Ph.D. Students • Christer Andersson • Stefan Lindskog • Reine Lundin • Albin Zuccato

  11. PriSec: Projects cont. • Privacy enhancement in Mobile Internet • Funding/Partners • HumanIT • Ericsson • Evaluation of privacy risks, especially those generated by the use of location data and user device specific CPI profiles • Minimal Profile Conveyance concept for conveying only minimal CPI profiles to non P3P-compliant, non P3P-enabled web sites or Push initiators • Development of browser built-in and a proxy-based P3P user agent for mobile Internet

  12. PriSec: Projects cont. • Privacy enhancing technologies in the next generation Internet • Funding/Partners • SCINT • KTH/IMIT • Investigate the privacy threats in IPv6 • Analyzed how Mix net technologies can take advantage of the IPv6 architecture • The use of P3P in IPv6 networks • Impact of proposal on lawful access to traffic data

  13. PriSec: Projects cont. • Dynamic Security Solutions for Networked Applications • Funding/Partners • Vinnova funding decision pending • Chalmers (Erland Jonsson) • Part of CMIT • Develop suitable security metrics for measuring and comparing the levels of various security parameters • Define, design, and implement more flexible and configurable security solutions that are based on a paradigm that allowsfor partial security.
