Din uppkoppling är okej! Mäta uppkoppling?

Utmaningar med nätverksmätning Prestanda? Datarate/kapacitet (megabit/s) Fördröjning/latens (ms) Tillförlitlighet (?) Säkerhet (?) Energiförbrukning (watt?) QoS / QoE … Tillförlitlighet till datan? Verktyg Repetitioner Vantage points C X X X X t

Utmaningar med mobilt bredband Radiokanal… Signal varierar med avstånd till basstation Signal varierar med hastighet Överlämning Störningar, interferens, skugga Öka kodning Gör omsändningar / H-ARQ … men överliggande protokoll då?

5GENESIS PROJECT PARTNERS The 5GENESIS project has received funding from the EU Horizon 2020 research and innovation programme under grant agreement No815178. More info at www.5genesis.eu

Example Experiment: Roaming Roaming is a complex procedure

Roaming – Impact on Performance 16 MNOs 6 countries Traceroute: path discovery Dig: DNS lookup Curl: data transfer Scenario You live in Sweden and decide to travel to Italy. In Italy, you can use your Swedish (Roaming) SIM or buy an Italian (Visited) SIM You then surf to a home server in Sweden, or Visited server in Italy. What’s the latency impact?

Example Experiment: Web browsing Motivation: Find out the major factors affecting web performance and quantify their impact Run large-scale, repeatable and reproducible experiments with intertwining technologies, protocols, and setups. Compare 3G/4G MBB performance of browser and different protocols, operators, networks Open-data for further analysis

Web browsing – Key Findings 3G and 4G HTTP/2 and QUIC Firefox and Chrome QoE metrics: FP, PLT, SI 11 MNOs 4 countries 100+ locations Stationary, Mobile, Eth 2,000,000+ page visits Distribution of FP for Chrome Distribution of SI for Chrome

“Web” – Key Findings Significant penalties for MBB users Network impact: Significant penalties for MBB users Mobile nodes suffer further penalties due to changing channel conditions and handovers Protocol impact: Marginal benefit of using HTTP/2 QUIC does not improve performance Machine Learning: Used to identify the most influential factors Highlighted features: RAT, mobility, browser, webpage composition, etc.

5GENESIS HIGH LEVEL OBJECTIVES 5GENESIS is one out of three selected projects in the 5GPPP ICT-17 call for building the 5G testbeds that will be used to validate the KPIs and the performance of verticals. The Project just started in July 2018.

The five platforms of the 5GENESIS Facility Athens Platform. An edge-computing-enabled shared radio infrastructure (gNBs and small cells), with different ranges and overlapping coverage that are supported by an SDN/NFV enabled core, to showcase secure content delivery and low latency applications in large public-events. Málaga Platform. Automated orchestration and management of different network slices over multiple domains, on top of the 5G NR and fully virtualised core network to showcase mission critical services in the lab and in outdoor deployments. Limassol Platform. Radio interfaces of different characteristics and capabilities, combining terrestrial and satellite communications, integrated to showcase service continuity and ubiquitous access in underserved areas. Surrey Platform. Multiple radio access technologies that can support massive Machine Type Communications (mMTC), including 5G NR and NB-IoT, combined under a flexible Radio Resource Management (RRM) and spectrum sharing platform to showcase massive IoT services. Berlin platform: Ultra dense areas covered by various network deployments, ranging from indoor nodes to nomadic outdoor clusters, coordinated via advanced backhauling technologies to showcase immersive service provisioning.
