[GGIE] DRAFT bof proposal for IETF 98 in Chicago

["Leslie Daigle" <[e-mail]>]

Hi,

Please find below a proposal for a GGIE BoF (WG-forming) at IETF 98 in 
Chicago.  We will be submitting the proposal by the deadline this 
Friday, but would be happy to have suggestions to improve the proposal 
before then.

One of the things we’ve beed advised is that 
GGIE-proponents-other-than-Glenn-and-Leslie are pretty invisible to the 
IESG.  If there doesn’t seem to be other interest, there won’t be 
much justification for a BoF.

Now is the time, and here is the place, to voice your support for 
furthering this discussion!

Thanks,
Leslie.

Name: Glass to Glass Internet Ecosystem (GGIE)

Description:

Video is without rival the top use of Internet bandwidth, and its ever 
growing demand for more bandwidth easily out paces the new capacity 
being added both globally and regionally with no let up in sight.   
Users are frustrated by quality, buffering, and stuttering problems. 
Video providers and access networks are investing heavily to keep up 
with demand.  Significant work has be done at the application layer 
producing more efficient codecs and innovative adaptive bitrate 
transports like MPEG-DASH.  These access investments and application 
layer work have helped but they alone have not been enough.

This BoF will introduce the Glass to Glass Internet Ecosystem (GGIE) 
which focuses on network level innovations to compliment the efforts at 
the application layer and access networks.  The proposed GGIE work 
includes enabling adaptive bitrate transports like MPEG-DASH to use IPv6 
as their video segment addressing scheme which in turn permits use of 
advanced IPv6 network features such as Segment Routing.  A GGIE goal is 
to enabling video and network routing and management to work more 
cooperatively and efficiently to transport video, and to do so in a 
backward compatible ways to permit exiting devices and players to take 
advantage of the improved network efficiencies.

Glass to Glass Internet Ecosystem (GGIE) -- Draft Charter

Due to its size and sensitivity to network conditions, the transport of 
video over the Internet has highlighted a significant scalability 
problem for the Internet.  Addressing this scalability problem requires 
better integration between application transport and networking 
technologies and leveraging IPv6.  The GGIE working group will define a 
set of fundamental building blocks bridging video application use of the 
network and core network services of addressing, routing, and naming. 
Through standardization, of such fundamentals, a common base platform 
for new interoperable innovation on video transport efficiency and 
scalability will be enabled.

The scalability problem is driven by both professional and user 
generated content, fortunately both types of content use the same 
transport technologies which permits the working group’s output to 
apply equally to them. Likewise, in addition to the use the network to 
transport video for viewing, the network is extensively used in video 
creation workflows of capture and editing, and distribution workflows of 
encoding, packaging, and distribution to edge caches for playback.   The 
working group will address both viewing and creation/distribution 
workflows.

To that end, the GGIE working group will define missing pieces of 
Internet technology standards, as well as provide pointers to use of 
existing standards.

Specifically, the GGIE working group will:

+ complete an overview document outlining the GGIE problem statement and 
general solution approach
+ develop a set of use cases representative of GGIE problem scope
+ develop a standardized URI for referring to specific media objects 
within a domain
+ develop a standardized means for mapping IPv6 addresses to video data
+ develop a media address resolution service protocol (MARS) to map URIs 
and addresses for video
+ provide a mechanism for discovering media address resolution services
+ document integration methods with lower level fundamental network 
services (eg. routing)
+ develop media encoding network (MEN) definitions for video packaging 
such as MPEG-DASH
+ illustrate how these technologies address the use cases already 
developed for GGIE

Out of scope are:  video technologies including codecs, digital rights 
management, and DRM enforcement technologies.
