AR/VR applications need both low latency and high throughput. We shall see that
the ratio of peak to mean bit-rate makes it extremely challenging to hit both
targets, even as a niche managed service. The greater challenge is how to hit
both targets routinely - for the mass-market. This either needs both low
latency and highly variable bandwidth to be feasible as part of the regular
unmanaged Internet service, or it needs simpler managed QoS services that would
be available routinely for everyone.

We look forward, quantifying the possible scale of the problem in about
5-10 years (2022-2027). The problem for the transport community can be reduced
by innovations at the application layer in coding, compression, and prediction.
Also, it would help if access networks were designed for a higher degree of
multiplexing between users. This first draft sizes the worst-case problem for
the transport community (which seems near-impossibly hard). The aim is to use
the first draft to draw out experts in application-layer and access-network
design to quantify how much of the problem they can absorb. This will help us
improve our estimate of the size of the residual transport layer problem in
future draft(s).
