The network impact of a Windows 8 RT device on your network.

The network impact of a Windows 8 RT device on your network.

So someone had this question.  It’s a good one.  I didn’t know the answer so I found out….

 

Articles here and here would indicate that network traffic should be both intermittent and light.  So….lets check it out.

The Test:  I built a Windows 8 VM in my lab.  Updated it, updated default Windows Store Applications, created a new user account that I had never logged in as and then setup a netsh trace session from an elevated command prompt:

 

mkdir c:\trace

cd c:\trace

netsh trace LAN capture=yes report=yes tracefile=c:\trace\file.etl

 

And then I logged out and logged into the new ID.  The plan was to run it for 20-30 minutes but I went downstairs to talk to the wife and you know how that goes so an hour or so later I remembered my test!  Went upstairs and logged out, logged in as my administrator user and opened an elevated command prompt and did:

 

cd c:\trace

netsh trace stop

It looked like this:

Which isn’t horribly exciting, but the etl file and file.cab file are Smile

So I put them on my debugging machine via SkyDrive and went to town.

The Results:

Very little traffic, most of it in spurts, every 5 minutes as expected.

You can see it in the graphic above.  I’ll actually need to do a longer trace to get a better feel for statistics, but I wouldn’t sweat a Windows 8 RT or Pro device on your network.

  • How can i know the impact only in trace?

    is not safe...

  • The question that got me looking into this in particular was how many proxy connections does a single Windows RT device create.  From looking at a default configuration of live tiles updating, it appears to be one session from the WNS.

    The debate will shift then to how each application impacts performance of the network I suppose.

  • Nice post!  The proof is in the puddin'.
