Re: Updated IPP Firmware Update Extensions figure slides posted[EXTERNAL]

Hi Smith,

Slide 9 and Slide 13 I have comments on.

Slide 13 the cloud only scenario. It should clarify that the cloud can’t reach the printer on the user’s network, so it is up to the printer to reach up to the cloud first.
Slide 9 seems to have a verbiage conflict between arrow 3 and 4?

Greetings,

We agreed that I should post the slides we were using to model the scenarios and think about them and decide. Here's the slides:

https://ftp.pwg.org/pub/pwg/ipp/slides/IPP-Firmware-Update-Extensions-Registration-Options-20240912.pptx<https://urldefense.com/v3/__https:/ftp.pwg.org/pub/pwg/ipp/slides/IPP-Firmware-Update-Extensions-Registration-Options-20240912.pptx__;!!Iq1d47XejX0!jWwe-5IqYVrU0K_mMoNc0-Bw5qK8j9lhYwJYXQMkLuWQyOqjoKhbLFcMH3ORr8yH6hhNP8LqtN-Lx0k$>

Here's PlantUML for Scenario #1:


@startuml



title
Firmware Update Scenario 1: Client Managed Firmware Update

autonumber

skinparam
sequenceMessageAlign direction



participant
Client

participant
Printer

participant
Repository



Client
-> Repository: Firmware update available?

Repository
-> Client: Download firmware update

|||

Client
-> Printer: Send firmware update to Printer

Client
-> Printer: Monitor firmware update progress

Here's PlantUML for Scenario #2:


@startuml



title
Firmware Update Scenario 2: Autonomous Printer Firmware Self-Update

autonumber

skinparam
sequenceMessageAlign direction



participant

Printer

Printer
-> Repository: Firmware update available?

Repository
-> Printer: Firmware Self-update



@enduml



Here's a longer PlantUML for Scenario #3, incorporating both Check-For-Firmware-Update and Update-Printer-Firmware but no scheduling:


@startuml

Firmware Update Scenario 3: Triggered Self-Update

Printer

Printer

Client
<- Printer: Firmware update is available

end
group





group
Client triggers
Printer to
self-update

Client
-> Printer: Update Firmware

Printer
-> Repository: Firmware Self-update

Repository
-> Printer: Firmware update

Client
--> Printer: Monitor firmware update progress

Printer
-> Printer: Update firmware

Client

Printer
-> Printer: Reboot

Client
--> Printer: Monitor firmware update progress

Printer
-> Printer: Update complete

end
group

Feel free to post updates to the slides or tweaks to the PlantUML UML sequences.
