Guide to Large Sessions

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, pre-recorded 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.
