Hi Dirk,

Thanks for the suggested additional dimension for the use cases.  The use case referenced is an interesting one indeed (user interactivity and personalization added on top of https://www.kcl.ac.uk/news/the-worlds-first-5g-low-latency-3-way-distributed-orchestra-at-kcl)! Could not find a link however to haptic communication aspect. Maybe can provide a haptic experience that is in sync with music for users who are disabled and can't perceive audio and/or video? 

By dynamicity do you mean how different user profiles and user interactions are taken into consideration, in multi-user scenarios? And how the resulting user-specific information (of the same experience) being transferred to users  (audio-video-haptic) ? If yes, certainly it is another dimension of the use cases, e.g., Entertainment (gaming), Training (training simulations). For example, in scenarios where virtual simulation environments used for training, where multiple users act upon the same virtual objects, the information received by individual 'trainee users' may differ due to 1) user preferences (e.g., with haptic feedback vs without) 2) individual user's perception (e.g.., audio, video haptic) of objects and actions/events within the virtual environment (e.g., based on viewpoint, distance to objects/events, and properties of virtual objects [different users may receive different haptic feedback depending on the type of actions performed], experiences may differ per each user). Moreover, the trainer (human or virtual) may choose to provide corresponding feedback (using audio-visual or audio-visual-haptic mediums) to an individual or a group/subset of trainees in real-time. Such an experience must be provided while meeting stringent latency requirements imposed by haptic. We may add the aforementioned aspects related to dynamicity into the use cases in the next version of the draft.

Best regards,
Chathura

Hi Chathura,

Interesting draft, indeed, to start a discussion here on this list. Adrian's responded with a piece I'd also recommended, namely the SARAH list, where this contribution may well contribute to possible discussions on addressing and routing aspects related to the Tactile Internet. 

Apart from that, I wonder about the degree of dynamicity that you foresee in your scenarios (of Section 4)? The use case draft in the COIN RG (https://datatracker.ietf.org/doc/draft-irtf-coinrg-use-cases/) outlines an entertainment use case with a personalized and interactive nature, where dynamic relations, e.g., between (parts of the) performers and (parts of the) audience are foreseen. The tactile notion is not emphasized here, leading to higher acceptable latencies maybe (although when mixing distributed music, you are still down at few ms latency). But it's the dynamic relations that I wanted to point out, which pose additional requirements. This may also be the case for industrial use cases, BTW. Maybe something to consider as a possible dimension?

Best,

Dirk

Dear all,

Please find below our new draft submission on Tactile Internet Service Requirements.

This draft introduces tactile internet use cases and service requirements potentially to be used as input for further discussions and/or to be directly addressed by IETF.

Comments and feedback are warmly welcome!

Best regards,
Chathura

A new version of I-D, draft-sarathchandra-tactile-internet-00.txt
has been successfully submitted by Chathura Sarathchandra and posted to the IETF repository.

Name:		draft-sarathchandra-tactile-internet
Revision:	00
Title:		Tactile Internet Service Requirements
Document date:	2021-06-25
Group:		Individual Submission
Pages:		11
URL:            https://www.ietf.org/archive/id/draft-sarathchandra-tactile-internet-00.txt

Abstract:
   The Tactile Internet refers to a new communication and networking
   paradigm, which can provide low-latency, reliable and secure
   transmission for real-time information such as control, touch, and
   sensing/actuation in emerging tactile internet applications like
   teleoperation, immersive virtual reality,and haptics communications.
   The main goal of this document is: 1) to briefly introduce tactile
   internet background and typical applications; 2) to identify
   potential service requirements that can be addressed at the IETF or
   researched at the IRTF.
