__________________________________________________________
Intros
Anssi: from Intel - got involved as it was being set up,
helping with some practical aspects
... I'm also involved in other W3C work related to this IG: the
Devices and Sensors Working Group has an API to allow access on
network connections from Web apps
... the Network Information API - currently in incubation
... it would be useful to understand which use cases would
benefit from this API (if any)
... we're looking for guidance on this in the Devices and
SEnsors Working Group
... I'm also chairing the Machine Learning for the Web
Community Group
... this group has in scope an API for doing neural network
inferences in browsers
... here again, the IG is of interest for this effort - there
is a use case where a Web app might want to either do
inferencing in the browser or in the cloud depending on network
characteristics
... Beyond that, I'm involved in a bunch of other W3C groups -
less directly connected
Eric: Eric Siow from Intel
... I got involved in this group as I was asked to chair the
Web5G workshop in London in 2018
... a result of the workshop was that we needed to focus on
problem statements
... based on input from a number of operators and other
stakeholders, we were able to identify the need for better
cooperation between apps and networks
... we thus expanded the scope beyond 5G to cover networks
interactions in general
... I'm also a newly elected W3C Advisory Board member - with
that hat, I'm hoping to see renewed engagement from operators
Jonas: Jonas from Intel
... been working with base stations and 3GPP RAN
<surfufu> i am late ?
Jonas: working on 5G - we see the need for better awareness
from apps on network variations
... I was approached by Eric - this sounds like a good way to
bridge networks and apps
Picky: Picky Butani - consultant with Austin Energy
... my interest with Web & Networks arised when starting
working in a Web-based blockchain service
... I hope to get information from the group on how to support
this project
... I've been looking into phishing attacks in the context of
5G
... interests in AI, NN, Fuzzy networks, blockchain
Sudeep: from Intel as well :)
... I work primarily in the Comms domain, quite recently in the
virtualization space and machine learning
... started my carreer in signal processing
... stepped a few years ago in the standardization space, first
in India
... pretty new to W3C, got involved through Eric, Anssi, Dom
... trying to see how we can solve to enable the next
generation of developers
... how can we address some of the problems coming from the
elements in the network
... seeing quite a few use cases where offloading to the
network, to the cloud becomes interesting
... want to see how we can enable these new approaches
Song: work for China Mobile / Migu
... also delegate to 3GPP SA4 Codec WG
... and expert in 5G Joint WG from China Mobile; I have been
involved in standardization for quite a while
... I'm working for a China Mobile subsidiary, Migu, developing
exclusively internet-based services (gaming, media, etc)
Zoltan: from Intel, previously with Nokia, previously AI and
robotics researcher
... I have been involved in WebNFC, Web Bluetooth, Device and
Sensors, currently involved in Web of Things, esp Smart Cities
where issues around scalability and latency are most important
Jonathan: from Intel - working on the performance side of the
Web, e.g. JS or rendering
... also involved in WebRTC
Nicolas: working for 3DRudder, involved in gaming industry, was
involved in Khronos
... 3DRudder enables a new locomotion device for VR
... I'm interested in understanding how WebVR works on the
server-side
... which needs good transmission of 3D data
IG Intro
[10]Slides

Use cases and requirements
[11]Sudeep's slideset on use cases and requirements
[11]
http://lists.w3.org/Archives/Public/www-archive/2019Jun/att-0000/W3C_WnN_IG_26Jun_2019.pdf
Sudeep: [presenting slides on Use cases and requirements]
... we wanted everybody to bring use cases - lots of new things
happening around e.g. cloud gaming, containerization, etc
... we think a good first step is to document these use cases,
probably on github
... and based on that derive requirements
... we have TPAC in our roadmap where we could discuss these
use cases and requirements
zkis: it would be good to raise issues for use cases and
collate them into a separate directory in the github repo
[12]web-networks github repo
[12] https://github.com/w3c/web-networks/
Sudeep: makes sense - I'll provide a template to that end
... I hope we can manage to meet twice in the upcoming 2 months
before TPAC
... call to ACTION: please start thinking about and sharing use
cases
... I've created a one-pager slide that can serve as a template
for use cases
... we can derive requirements from a use-case by use-case
basis, and then we would collate them together
... I'll share a few examples of use cases based on that
template
... the use case can be shared as a slide first, before we
bring them into github content
Anssi: I think it may be easier to have one github issue per
use cases
... this allows for feedback, and enables adding images, etc
... can also be cross-linked from other repos
... I could use this to make a call-for-use-case in machine
learning cg
zkis: it's easier to comment on issues
Sudeep: I'll do this
Anssi: we could even create an issue template
... but the most important thing for now is to get input, in
any format
Sudeep: will follow up on this
... We have collected a few use cases as inspiration
... my colleague Jonathan has one on Cloud Gaming to share
Jonathan: Cloud Gaming can have 2 modes: game engine in the
cloud, which will depend on parameters of the network (latency,
data plan, etc)
... if the network parameters vary and make the cloud-based
approach no longer workable, it would be nice to fallback on a
local-mode engine
... you could switch back again as the network circumstances
evolve
... this leads to requirements on the UA to monitor network
parameters and notify changes through events
... you could also imagine a user agent sticking to a specific
network with the right parameters
Picky: could this be implemented by geo-settings instead?
<Eric> I lost audio. Is it just me?
Jonathan: good question
Picky: if the network is very slow or has too low performance,
we can fallback to another server based on geolocation
... you have to ensure transaction continuity in that case
Conclusions
Dom: Please send your use cases (to the list, to github, as you
see fit)
... make sure to register for TPAC if you're planning to attend
the F2F
... we will organize a Doodle to set up our next call end of
July
... and review use cases and requirements
