4 DISCO: Projects SCTP for soft real-time applications Funding/Partners Tieto Enator AB (Karl-Johan Grinnemo)Continuation of 4 year cooperationPart of CMIT platformConsequences of SIGTRAN on transport performancePerformance of M3UA Failover MechanismsSee presentation by Karl-Johan GrinnemoGeneral performance evaluation of SCTPPartial Reliability in SCTPBuilds on previous work on partial reliability: PRTP, PRTP-ECN, Robust JPEG coder
5 DISCO: Projects cont. Protocol support for mobile environments Funding/PartnersTelia Mobile AB (Jan Gustafsson, Jonas Eriksson)Dr. Juan Rendon, UPF, SpainPart of CMIT platformMeasurements of TCP over GPRSGPRS testbedReal nodes and protocol implementationsEmulated radio environmentSee presentation by Annika Wennström
6 DISCO: Projects cont. Wireless IP Funding/Partners SSFUppsala University (Anders Ahlén, Mikael Sternad)Chalmer (Arne Svensson, Tony Ottosson, Mats Viberg)Saverio Mascolo, Bari, Italy, Torbjörn Ekman, Unik, Norway, Ericsson, NERAA 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 fairnessLeads 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 InformationFunding/PartnersVinnovaUppsala University (Anders Ahlén, Mikael Sternad)Chalmer (Tony Ottosson)Related to Wireless IP projectDevelop means to propagate soft information from the physical layer to the applicationJPEG 2000 decoder that utalizes soft informationTCP-L, protocol that lets biterrors throughDevelop efficient scheduling algorithms among multiple access points
8 DISCO: Projects cont. EU FP6 projects WINNER Wireless World Initiative New RadioIntegrated ProjectWireless IP partner with Chalmers as main contactCoordinator: Dr. Werner Mohr, Siemens AGNEWCOM Network of Excellence in Wireless CommunicationsNetwork of ExcellenceCoordinator: Prof. Sergio Benedetto, Istituto Superiore Mario Boella, Italy
9 DISCO: Projects cont. Other Activities Transport Layer Loss Differentiation and Loss NotificationDistinguish the cause of a packet lossInform transport sender of cause: explicitly or implicitlySee presentation by Johan GarciaMeasurement TechniquesImpact of the position for packet lossTime-driven versus data-driven biterrors

11 PriSec: Projects cont. Privacy enhancement in Mobile Internet Funding/PartnersHumanITEricssonEvaluation of privacy risks, especially those generated by the use of location data and user device specific CPI profilesMinimal Profile Conveyance concept for conveying only minimal CPI profiles to non P3P-compliant, non P3P-enabled web sites or Push initiatorsDevelopment 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 InternetFunding/PartnersSCINTKTH/IMITInvestigate the privacy threats in IPv6Analyzed how Mix net technologies can take advantage of the IPv6 architectureThe use of P3P in IPv6 networksImpact of proposal on lawful access to traffic data
13 PriSec: Projects cont.Dynamic Security Solutions for Networked ApplicationsFunding/PartnersVinnova funding decision pendingChalmers (Erland Jonsson)Part of CMITDevelop suitable security metrics for measuring and comparing the levels of various security parametersDefine, design, and implement more flexible and configurable security solutions that are based on a paradigm that allowsfor partial security.
