About byte-level checkpoint restart and dynamic bandwidth throttling

Endpoint Manager 8 and later versions support distribution byte-level checkpoint restart and dynamic bandwidth throttling. Checkpoint restart works with distribution jobs that SWD first copies to the device cache folder (by default, C:\Program Files (x86)\LANDesk\LDClient\SDMCACHE). When a bandwidth controlling option is selected, the files get copied to the device cache first, and checkpoint restart allows interrupted distributions to resume at the point where they left off.

Dynamic bandwidth throttling specifies that the network traffic a device creates has priority over distribution traffic. This option also forces a full download of the file into the device's cache, which also enables byte-level checkpoint restart, where downloads resume where they left off if interrupted. If you select this option and leave the Minimum available bandwidth percentage at 0, once the device initiates network traffic, the distribution cuts back to about one packet per second until the traffic stops. Increasing the minimum available bandwidth preserves approximately the amount of device bandwidth you specify for distribution if the distribution needs network bandwidth and there is contention for bandwidth on the device.

If you're reinstalling or repairing an SWD package or an MSI package, you may not want to use the dynamic bandwidth throttling option, because these package types normally only download the files they need. Using dynamic bandwidth throttling in this case would force a full download of the package when a repair might normally only require a small portion of the package.

You can configure collective bandwidth throttling so that only one device from the multicast domain will download from the remote source. You can also configure the amount of bandwidth used when downloading from the source.
