1 doc.: IEEE 802.11-13/0728r1 SubmissionSlide 1 Network Optimization for Expected HEW Traffic Patterns Date: 2013-07 Authors: W.Carney, K.Agardh, H.Suzuki (Sony) July 2013

2 doc.: IEEE 802.11-13/0728r1 Submission Abstract This presentation discusses the need for optimization of HEW networks for both video services and bursty data with short packets. To account for high QoE for these expected traffic types, we suggest two criteria for the evaluation of HEW proposals. July 2013 Slide 2W.Carney, K.Agardh, H.Suzuki (Sony)

3 doc.: IEEE 802.11-13/0728r1 Submission Data Traffic Patterns What kind of data will flow through HEW networks? Video –Expected to drive the main data volume “Two-thirds of the world’s mobile data traffic will be video by 2017” –Support video traffic in both UL and DL Social networking, including OTT (e.g. Skype, Facebook) and IMS –Always active background traffic –Minor part of total data volume –Including Voice over IMS (VoLTE / VoWiFi) Web –Bursty data of all sizes –Real time (E.g. WebRTC) and non-real time applications (Browsing) July 2013 Slide 3W.Carney, K.Agardh, H.Suzuki (Sony) Ref: Cisco Visual Networking Index: Global Mobile Data Traffic Forecast Update, 2012–2017

4 doc.: IEEE 802.11-13/0728r1 Submission Video Content Characteristics Display resolution increase in all CE devices –E.g., support for 4K & 8K/Ultra-HD by time of HEW completion Video typically uses the available bandwidth to increase resolution/fps and decrease compression losses Active session during a defined time period Utilizing full Ethernet frames 1500B Allows long aggregated frames Allows buffering Short transport level ACKs in opposite direction July 2013 W.Carney, K.Agardh, H.Suzuki (Sony)Slide 4

5 doc.: IEEE 802.11-13/0728r1 Submission VoIP (OTT and IMS) Characteristics Voice over 3GPP and 802.11 will be seamless Packet inter arrival times typ. 20 - 40 ms Packet sizes 35-70 Bytes for VoIP High latency requirements Frames can not be aggregated Data can not be buffered Small raw data volume, but high number of individual packets July 2013 W.Carney, K.Agardh, H.Suzuki (Sony)Slide 5

6 doc.: IEEE 802.11-13/0728r1 Submission Web Traffic Packet Size Distribution Figure shows distribution of UL and DL packet size for random web browsing Ref: Anatomy of Wi-Fi Access Traffic of Smartphones and Implications for Energy Saving Techniques, R Palit et al. Research and network statistics show that a large part of traffic is <100 Bytes. For example transport ACKs, web browsing and social networking traffic July 2013 W.Carney, K.Agardh, H.Suzuki (Sony)Slide 6

7 doc.: IEEE 802.11-13/0728r1 Submission Burst Size per Traffic Type Distribution of UL burst size Ref: Anatomy of Wi-Fi Access Traffic of Smartphones and Implications for Energy Saving Techniques, R Palit et al. Looking at bursts of packets For all traffic types, absolute majority of UL bursts are < 1500 Bytes Social networking (like voice, Skype, Facebook) bursts are < 100 Bytes UL video expected to increase, so no clear asymmetry between STA and Infrastructure Distribution of DL burst size July 2013 W.Carney, K.Agardh, H.Suzuki (Sony)Slide 7

8 doc.: IEEE 802.11-13/0728r1 Submission Data Traffic Patterns - Conclusions Data characteristics Video –Causes the main data volume in one direction –Small ACK packets in the other direction –Similar network requirements, regardless of the data direction Social networking, including IMS –Always active background traffic –Minor part of total data volume, but major amount of data packets –Streaming real time voice and video disallows buffering and aggregation July 2013 Slide 8W.Carney, K.Agardh, H.Suzuki (Sony)

9 doc.: IEEE 802.11-13/0728r1 Submission Evaluation Criteria: Summary and Next Steps HEW system must prioritize not only maximizing capacity for bulk data and high throughput, but also highest efficiency for short packets <100 Bytes –Comparison/evaluation of header overhead and efficiency of packet sequencing/prioritization Capabilities of MAC protocol proposals need to be demonstrated for a distribution of packet sizes and bursts, not only 1500 Bytes –An appropriate network traffic model is needed July 2013 Slide 9W.Carney, K.Agardh, H.Suzuki (Sony)
