[tsvwg] draft-ietf-tsvwg-nqb-15.txt - Definition of gaming/game traffic

[[e-mail]]

Hi Greg,

Please provide a definition of "games and gaming, respectively" and clarify to the reader, that you define this term in a technical sense for draft NQB, before you start using it. I've found:
- low-data-rate online gaming
- Current examples include many online games,..
- draft-ietf-tsvwg-aqm-dualq-coupled: Both Classic and L4S services can cope with a proportion of
      unresponsive ..traffic....(e.g. DNS, VoIP, game sync datagrams, etc.)
- https://www.rfc-editor.org/rfc/rfc9331.html: this document discusses the conditions for mixing other "'Safe' Unresponsive Traffic" (e.g., DNS, LDAP, NTP, voice, and game sync packets). 1 of 5 times, always "game sync packets"
- https://www.rfc-editor.org/rfc/rfc9332.html: unresponsive traffic.... (e.g., DNS, Voice over IP (VoIP), game sync datagrams, etc.).

I don't understand, why the definition of game related traffic differs between RFC's 9331, 9332 (where game related terminology is applied stringent as "game sync packets") and standards track draft NQB. In the latter, game/gaming appears twice, diverges for some untold reason from L4S terminology and isn't defined stringently within the doc. Please use "game sync packets" through draft NQB, as this is compliant with text of RFCs 9331 and 9332.

Regards,

Ruediger

        Title           : A Non-Queue-Building Per-Hop Behavior (NQB PHB) for Differentiated Services

Abstract:
   This document specifies properties and characteristics of a Non-
   Queue-Building Per-Hop Behavior (NQB PHB).  The purpose of this NQB
   PHB is to provide a separate queue that enables smooth, low-data-
   rate, application-limited traffic flows, which would ordinarily share
   a queue with bursty and capacity-seeking traffic, to avoid the
   latency, latency variation and loss caused by such traffic.  This PHB
   is implemented without prioritization and can be implemented without
   rate policing, making it suitable for environments where the use of
   these features is restricted.  The NQB PHB has been developed
   primarily for use by access network segments, where queuing delays
   and queuing loss caused by Queue-Building protocols are manifested,
   but its use is not limited to such segments.  In particular,
   applications to cable broadband links, Wi-Fi links, and mobile
   network radio and core segments are discussed.  This document
   recommends a specific Differentiated Services Code Point (DSCP) to
   identify Non-Queue-Building flows.
