Connect Default Bandwidth Adjustments for On Premise Deployments

In addition to other parameters (like chat pod character limits, connection light thresholds,  etc.) you can adjust the default bandwidth and performance settings for your Adobe Connect meeting room experience via the configuration file reference below. This is applicable for On-Premise installations of Adobe Connect only, and is not for Hosted Adobe Connect accounts.

The location of the internal configuration file on Adobe Connect 9.1.1:
{InstallDir}\9.1.1\comserv\win32\conf\originhost\_defaultVHost_\Application.xml

You can throttle these up or down to suit the needs and requirements of your network or infrastructure.
Note: You must cycle the Connect services after making any changes to this file on every node in your cluster (if more than one origin server).

Room Bandwidth Settings:

bw-room

The first setting you can modify relates to the Optimize Room Bandwidth setting inside of the Meeting > Preferences > Room Bandwidth area of the Meeting UI.  This option gives you the three  Room bandwidth options of ‘LAN’, ‘DSL/Cable’, and ‘Modem’.  These settings throttle production based on the room settings and their associated values below.

These contain the bandwidth settings for ‘Client to Server’ as ‘C2S’ and ‘Server to Client’ as ‘S2C’.

  • ‘Up’ values are the C2S values (‘Client to Server’).  This is most important for screen sharing.
  • ‘Down’ values are the S2C values (‘Server to Client’).

All clients in the room will utilize this single setting.

In Connect 9.1.1 these options correlate to the following values (default):

Room Bandwidth Client to Server Server to Client
LAN 100000 KB/Sec 100000 KB/Sec
DSL/Cable 600 KB/Sec 800 KB/Sec
Modem 200 KB/Sec 200 KB/Sec

Room Bandwidth Settings in Application.xml: 

<BW_C2S_MODEM>200</BW_C2S_MODEM>
<BW_C2S_DSL>600</BW_C2S_DSL>
<BW_C2S_LAN>100000</BW_C2S_LAN>
<BW_S2C_MODEM>200</BW_S2C_MODEM>
<BW_S2C_DSL>800</BW_S2C_DSL>
<BW_S2C_LAN>100000</BW_S2C_LAN>

Camera Settings:

bw-video

The next values you can modify, correlate to the video settings at Meeting > Video > Video Settings > Video Quality, in the Meeting UI. This option gives you the ability to adjust the slider from the ‘Low’ to ‘High’ values.  The in-between values are actually ‘Medium’ and ‘Standard’.  All of these 4 options actually determine values for Quality, Frames Per Second (FPS), Max Resolution, and Max Widescreen Resolution.  As the menu in the UI indicates, the 4 quality settings are actually also affected by the previous Room Bandwidth setting as shown below:

9.1.1 Adobe Connect Camera Pod Settings (Default):

Screen Share Settings:

bw-ss

The last applicable setting is for Optimizations with Screen sharing.  In the UI, you can set it to ‘Low’, ‘Medium’, ‘Standard’, and ‘High’.  The below chart indicates what each of the values for these settings (for the ON2 SS Codec) actually are.

SS_ON2 Setting BW Limit Quality FPS Worst Quality Minimum Worst Quality
Low 500 65 2 1 1
Medium 800 80 4 30 15
Standard 1200 90 6 70 30
High 2000 100 8 90 50

Notes: 
SS_ON2_BW_LIMIT is in kb/sec.
SS_ON2_QUALITY defines the compression level (size vs quality).
SS_ON2_FPS defines the target number of frames per second to generate.
