1 VTT TECHNICAL RESEARCH CENTRE OF FINLAND DEMONSTRATIONS in Joint Easy Wireless and MAGELLAN Workshop "Quality of Service and Multimedia Communications for Heterogeneous Networks" Marko Jurvansuu, PhD Group Manager, Wireless Services VTT Electronics, Oulu

2 VTT TECHNICAL RESEARCH CENTRE OF FINLAND Timetable 12:00 Lunch VTT QoS Demos QoS-aware Gaming on Demand, Magellan, Ms. Tiia Sutinen Phone-based Mobile Service Testing, Easy Wireless, Mr. Marko Palola Application QoS Monitoring, Easy Wireless, Mr. Mikko Hanski QoS Support in 4G Networks -- The Daidalos Case Study, Antonio Cuevas Casado, Universidad Carlos III de Madrid, Spain DEMOS ARE SHOWN IN THE NEARBY HALL 10 meters from lecture hall

3 VTT TECHNICAL RESEARCH CENTRE OF FINLAND DEMO CATEGORIES NETWORK QoS MEASUREMENT APPLICATION ADAPTATION IMPROVED USER EXPERIENCE NETWORK QoS MEASUREMENT RESULTS ANALYSIS EVALUATED USER EXPERIENCE FACTORS DEMO 1: QoS-aware Gaming on Demand DEMO 2: Phone-based Mobile Service Testing DEMO 3: Application QoS Monitoring

4 VTT TECHNICAL RESEARCH CENTRE OF FINLAND DEMO 1: QoS-Aware Gaming-on-Demand Real-time video coding adaptation method for game service Network monitoring tool Real-time video encoding parameter optimisation Partners: G-Cluster, Maxisat

5 VTT TECHNICAL RESEARCH CENTRE OF FINLAND DEMO 2: Phone Based Mobile Service Testing VTT has developed a novel method for GPRS/EDGE/3G cellular network QoS testing Real phones, networks and services under test - user experience is evaluated GPRS EDGE 3G Internet

6 VTT TECHNICAL RESEARCH CENTRE OF FINLAND Major differences in end- to-end round-trip-delay GPRS operators Phone models Significant differences found in 3G network end- to-end goodput First connection vs. next Content size Operator A Operator B

7 VTT TECHNICAL RESEARCH CENTRE OF FINLAND DEMO 3: Application QoS monitoring Tool for monitoring network traffic in end- devices Application independent - now VoIP is used Service development for VoIP operators and video conferencing service providers Development for mobile environment

8 VTT TECHNICAL RESEARCH CENTRE OF FINLAND Workshop material will be available tomorrow in :

9 VTT TECHNICAL RESEARCH CENTRE OF FINLAND Network monitoring: Measurements: throughput, RTT, RTT jitter, and packet loss Thresholds for congestion detection Rate adaptive video encoding: Changeable parameters: frame rate and quantization Stream’s throughput is adjusted to the available bandwidth User-perceived video quality is taken into account in adaptation  The service will be available over heterogeneous networks and links with varying QoS, thus providing better end-user experience

10 VTT TECHNICAL RESEARCH CENTRE OF FINLAND Application QoS monitoring Measures one way delay, jitter, packet loss and throughput Passive end-to-end method (possibility for multi-point measurements) Captures packets from data link layer and records information on network traffic Collected data is shared between monitoring ends to enable real-time monitoring Clock synchronization by GPS Application and transport layer independent Development to mobile phone environment
