Introduction:

There are many items in the configuration policy that can impact the network utilization of the product. This is a list of the most substantial of these along with details of when and if they should be used or not used. Here we list the most common of those and in what situations you may want to or not want to change them.

Background:
If you are operating within network bandwidth constraints and need to reduce network load from CA ITCM/ITCA, then these items may help you.
Environment:
These can be leveraged from any system running a DSM Explorer with admin rights to the product.
Instructions:
Component: CFFTPLUGIN
SETTING: DSM->Common Components->File Transfer Server->Throttling
CFFTPLUGIN
This setting can be used any time there is a need and will tell the native file transfer plugin what is the maximum amount of bandwidth it can use when performing a file transfer.
 
Component: NATIVE DTS AGENT
SETTING: DSM->Data Transport Service (DTS)->Data Transport Agent Plugin->Discreet Mode
User-added image
This feature can be turned on to tell DTS Agent to perform files transfers in a ‘low priority mode’ which essentially say “If there is no network utilization, use all available bandwidth, but if not, use only a small portion until bandwidth becomes available. This must be used with caution because it can greatly increase the amount of time DTS file transfers (typically to the Scalability Server systems) will take and can cause unacceptable delays in an environment with jobs that need to be run quickly.
 
Component: Software Delivery Based DTS
SETTING: DSM->Software Delivery->File Transfer-> (settings shown below)
User-added image
This controls the way DTS will transfer files when used by Software Delivery. The Maximum Parcel Size is a value in bytes that defines the largest ‘chunk’ of data that will be transmitted per send. The Throttle Factor defines how many twentieths of a second the DTA agent will ‘pause’ between sends. In this case we have values of 131072 or 128KB and 2/20 of a second pause between each parcel send. The pauses provide a window for other applications to use bandwidth before DTS continues the next ‘chunk’ of data sends. These can be used almost any time but must be tested and experimented with in each environment to find the best combination of settings to use.
 
Component: Remote Control
SETTING: DSM->Remote Control->Host->General->Force Bandwidth Limiter
User-added image
This setting can be safely used almost any time. It will allow you to cap the network usage of remote control sessions by defining a maximum bandwidth utilization value. Since this can reduce responsiveness or the RC session when using high quality modes, it is recommended to select a reduced number of colors in the RC connection dialog, to work better depending on how much you reduce the available bandwidth.
User-added image
Component: Transfer Object Server (DTS)
SETTING: DSM->Data Transport Service (DTS)->Transfer Object Server->Enable Wakeup On LAN
User-added image
If you do not need to use or rely on WAKE ON LAN functionality in your environment, turning this off is an easy way to reduce network chatter.
***NOTE: This setting must be changed IN CONJUNCTION with the next item below!
 
Component: Scalability Server SD Server
SETTING: DSM->Software Delivery->Scalability Server->Job Check: Disable Wake-On-Lan
User-added image
Along with the previous item, this can easily set to disable Wake-On-Lan if unneeded. Note that here you set the value to ‘TRUE’ to disable Wake On Lan, where in the previous setting, you set ‘FALSE’ to ‘not enable’ it.
