Hi,

For #2 below just wanted to add that at Intel we are looking at some use-cases for XR with EDGE over a wifi link. Hence, it will be good to get answers to some of these questions below for wifi.

Dibakar

Subject: [Mops] Some questions regarding draft Media Operations Use Case for an Augmented Reality Application on Edge Computing Infrastructure

Hi Everyone,

Picking up the discussion from 115 about our draft titled "Media Operations Use Case for an Augmented Reality Application on Edge Computing Infrastructure", we are trying to identify issues in XR media delivery in an operational sense that would be within the scope of the MOPS WG and it would be great to get some pointers from the WG.

1) The first issue is - is offloading to the edge the only solution to deal with the problems of heat dissipation of the XR devices and their limited battery power as they run computationally intensive tasks in our use case?

  *   Our draft focusses on leveraging the edge devices but we would welcome inputs from the WG that discuss other pertinent operational ways that could be solutions.
2) For the Edge computing solution for our use case, what kinds of underlying tech do we envisage- 5G, WiFi?

  *   How will the XR media delivery scale if we increase the number of users?
  *   How to ensure that the edge servers are adequately provisioned- how many servers;  what topology to connect them, where to place them, what capacity to assign to the links etc?
  *   How to migrate user's XR media state as they move?
  *   How to operationally  respond to changes in BW ,creation and destruction of logical associations between software components etc?
This is of course not an exhaustive list, but we wish to prioritize the most important issues that the WG feels are appropriate for inclusion in the draft, so it would be great to have everyone's feedback please!

Regards,
Renan
