Jigsaw is a virtual classroom designed with engagement and learning in mind.  As groups are looking to do larger and larger sessions, we want to do a quick review of what you should plan for if you want to do these large sessions in Jigsaw.

 

As of now, Jigsaw can manage up to 1,000 people per session.  When doing these larger sessions, we recommend no more than one (1) mic and web cam be used at a time.  If you are doing large sessions that are less than 1,000 people, you should check the information below or contact your Account Manager for our recommendations on the number of mics, web cams, etc.

 

Because virtual events are becoming more popular and they are drawing larger audiences we are working to expand the number of people that our large session program can manage.  We expect these numbers to increase over the course of this year, but for now we do not want to negatively impact any of your virtual events.

 


Quick Guidance

Jigsaw considers a “large session” to be 100 participants or more.  When in a large session, some care must be taken when deciding how many live audios/videos you should turn on, at the same time.  This guidance only applies to live audios/videos, the other features of the application (whiteboard, presentations, chat, prerecorded audio/video, etc.) do not have limitations.

If you are using Break-Out Rooms, for the purposes of this document, each Room is considered to be its own session, so the guidance here would apply to each Room individually.

 

“Audios/videos” means Live:  Web Cams, Microphones, Screen Sharing.

 

We can calculate how many audios/videos can be used:
(# of people in room)  X  (# of live audios/videos)  =  must be less than 1,600

 


Here are some quick examples…

100 People in the Room
  8 Web Cams
  10 Open Microphones
  1 Screen Share

 

…or
  12 Web Cams
  5 Open Microphones
  No Screen Share

 

…or
  5 Web Cams
  18 Open Microphones
  No Screen Share

 

 

250 People in the Room
  3 Web Cams
  2 Open Microphones
  1 Screen Share

 

…or
  5 Web Cams
  2 Open Microphones
  No Screen Share

 

…or
  1 Web Cam
  10 Open Microphones
  No Screen Share

 

 

500 People in the Room

  No Web Cams
  2 Open Microphones
  1 Screen Share

 

…or
  2 Web Cams
  2 Open Microphones
  No Screen Share

 

…or
  1 Web Cam
  4 Open Microphones
  No Screen Share

 

 

1,000 People in the Room
  1 Web Cam
  1 Open Microphone
  No Screen Share

 

…or
  No Web Cams
  3 Open Microphones
  No Screen Share

 

 


General Guidance and Calculation Details

Definitions/Information:

“Consumer” = 1 Person receiving from 1 Microphone, Web Cam, or Screen Share

So, as a basic example, if you have 100 people in a Room…

5 Users turn on Web Cam
5 Open Microphones
1 Screen Share

This means (in round numbers) there are 1,500 “consumers” being used.
100 people  X  5 Web Cams = 500 consumers
  +
100 people  X  5 Web Cams = 500 consumers
  +
100 people  X  1 screen share = 500 consumers

 

However, Screen Share uses the most resources, Web Cams use less, Microphones use the least. This means our math gets a bit more complicated…

1 Web Cam = 1.5 open Mics

1 Screen Share = 1.5 Web Cams (or 4.5 open Mics)

This means, if you use 2 less Web Cams, you can use 3 additional Mics. If you stop Screen Sharing, you could use an additional 1 or 2 Web Cams (or an additional 4 or 5 open Mics).

 

So, to revisit our example from above and make a “more correct” calculation, there would only be 950 consumers (not 1,500). The more correct formula is:

# People  X  # Web Cams
  +
# People  X  (# Microphones / 2)
  +
# People  X  (# Screen Shares * 2)

100  X  (5 + (5/2) + (1*2)). This means there are 950 consumers for this room.

 

200 People in a Session
16 Open Microphones
Since Microphones use about ½ the resources, the calculation would be:
200 people * (16/2) = 1,600 “consumers”

 

250 People
3 Users turn on Web Cam
4 Open Microphones
1 Screen Share
The calculation would be:
250 people * (3 Web Cams + (4/2) Mics + (1*2) Screen Shares) = 1,750 “consumers”. This is over the 1,600 consumer limit, so 1 or 2 Microphones should be turned off.
