[STDS-802-11] Example use of the term "reliability" in a completed 802 amendment

--- This message came from the IEEE 802.11 Working Group Reflector ---

Laurent and all,

The information below re: use of the term “reliability” in a completed 802.1 amendment may be of use in UHR SG resolution of comments on the draft P802.11bn PAR.

Thanks,

Dorothy

==========================

IEEE 802.1CB-2017 (available in the 2023 IEEE-SA download), Frame Replication and Elimination for Reliability provides one definition of reliability that corresponds to packet loss rates. The project’s PAR is here: https://development.standards.ieee.org/myproject-web/public/view.html#pardetail/4897 .

From the amendment: 1.2 Rationale

 “The reason for Frame Replication and Elimination for Reliability (FRER) is to increase the probability that a given packet will be delivered. It is expected that, in many applications, other means to increase the probability of delivery are likely to be used as well. When FRER is used over paths that are fixed to a specific topology, and that are protected against congestion loss (e.g., by using techniques described by IEEE Std 802.1BA™ [B1]), FRER can substantially reduce the probability of packet loss due to equipment failures.

 

From the amendment: 7.1.1 Goals and objectives

FRER, as specified in this clause, provides increased reliability (reduced packet loss rates) for a Stream by sequence numbering and replicating every packet, in the source end system and/or in relay systems in the network, and eliminating those replicates in the destination end system and/or in other relay systems.
