4 Karlstad University Computer Science 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 Karlstad University Computer Science 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 Karlstad University Computer Science 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 Karlstad University Computer Science 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
