How do I limit the bandwidth used by TEM Clients or the TEM Server?

Technote (troubleshooting)


Problem(Abstract)

The following article discusses bandwidth throttling settings available to limit the bandwidth used by the TEM Clients or the TEM Server.

Symptom

Many network environments have limited bandwidth between certain geographic locations, between offices and home users using VPNs, etc. Deploying large Microsoft patches (the Windows XP SP2 update is 275 MB!) can easily overwhelm limited bandwidth connections and cause bandwidth problems for certain users or applications.

To avoid these types of problems, TEM provides a number of mechanisms to reduce bandwidth usage including the use of TEM Relays, distributing patch deployment over time, and the use of bandwidth throttling. Bandwidth throttling allows the TEM Console operator the ability to set the maximum number of bytes per second to be used to send files over a network connection. TEM can be configured to throttle bandwidth at the TEM Server, TEM Relay, or TEM Client level. Below are instructions on how to configure TEM to use bandwidth throttling.

Important Note: In BigFix/TEM 5.0 and above the bandwidth throttling settings were moved to the "Tasks" tab on the BigFix Support Fixlet site instead of using custom settings. Please view Tools > Show BigFix Client Settings Tasks and Tools > Show BigFix Server and BigFix Relay Settings Tasks in the TEM Console for more information. In addition, there is an Analysis that can be activated that will display the bandwidth throttling status of BigFix/TEM Clients.

Methods of Bandwidth Throttling

Throttling through TEM Relays (A)

TEM Relays downloading from the TEM Serve
r
TEM Relays can be configured to throttle file downloads when downloading from the TEM Server. When TEM Relay throttling is enabled, the TEM Relay will download from the TEM Server no more than the specified number of bytes per second. This setting is especially useful for TEM Relays that have a slow connection to the TEM Server (such as a TEM Relay in a remote location connected by a 56 kbps modem).

Configuration: TEM Client throttling can be configured by using the "_BESGather_Download_LimitBytesPerSecond" setting on the TEM Relays. Information on how to configure this setting can be found here.

Total outgoing download traffic for the TEM Relay:
The BigFix/TEM Relay in BigFix 4.0 and above can be configured to throttle the cumulative file downloads at any given time. When this throttling setting is enabled, a TEM Relay will send out no more than the specified number of bytes per second for all file downloads (including TEM Clients and child TEM Relays). This setting is especially useful if there is a concern in a local area network that too much bandwidth will be used when a patch is sent simultaneously to many TEM Clients.

Configuration: TEM Relay cumulative download throttling can be configured by using the "_BESRelay_HTTPServer_ThrottleKBPS" setting on the TEM Relay. Set this number to the total number of kilobytes that the TEM Relay will give to all of the TEM Clients combined per second.

Throttling through TEM Clients (B)

TEM Clients downloading files from the TEM Server or TEM Relay

TEM Clients can be configured to throttle file downloads when downloading from the TEM Server or TEM Relays. When TEM Client throttling is enabled, a TEM Client will download from the TEM Server or TEM Relays at no more than than the specified number of bytes per second. This setting is especially useful for individual computers that are on slow connections (such as travelling sales representatives or home users on dial-ups).

Configuration: TEM Client throttling can be configured by using the "_BESClient_Download_LimitBytesPerSecond" setting on the TEM Clients. Information on how to configure this setting can be found here.

Throttling through the BigFix Server/Relays (C/D)

Total outgoing download traffic for the BigFix Server/Relays

The TEM Server can be configured to throttle the cumulative file downloads at any given time. When this throttling setting is enabled, the TEM Server/Relays will send out no more than the specified number of bytes per second for all file downloads (including TEM Clients and child TEM Relays). This setting is especially useful if there is a concern in a local area network that too much bandwidth will be used when a patch is sent out to many TEM Clients simultaneously.

Configuration: TEM Server cumulative download throttling can be configured by using the "_BESRelay_HTTPServer_ThrottleKBPS" setting on the TEM Server. Information on how to configure this setting can be found here.
