Instructions for installing all the tooling needed to do Windows 10 1903 device driver development (Assuming Visual Studio is already installed). It also includes steps to get up and running with the 'inspect' sample for WFP Callout driver development.
In addition to getting the tooling installed for driver development on Windows 10 1903 I have also included instructions for getting up and running with the
Windows Filtering Platform sample Inspect which is a sample callout driver for doing packet inspection.
The first step is to install the Windows 10 SDK. This is required to build the drivers and needs to match the version of the WDK that you will install in the next step.
- Navigate to Windows 10 SDK Download Page
- Click on
Download The Installer

Results from some tracing into the calls to get_crandom in sch_netem.c
The function below is responsible for returning the delay value that is used by the qdisc. If no distribution is specified it is uniform, this is why I didn't see a uniform.dist file in /usr/lib/tc where the other distribution tables are.
mu == latency
sigma == jitter
You can see from the code below that if you don't specify a distribution then it uses the uniform one by default. return ((rnd % (2 * sigma)) + mu) - sigma; in this case rnd is our correlated random number from get_crandom so we take the jitter value sigma and multiply it by 2, then we modulo rnd by this value and add mu our base latency and then subtract sigma to center the jitter
