version:6.0.8970.161     FileName: network-assessment-lib-6.0.8970.161.zip

The Skype for Business Network Assessment Tool provides the ability to perform a simple test of network performance to determine how well the network would perform for a Skype for Business Online call. It’s aimed specifically at testing your connectivity to Skype for Business Online

The tool tests the connection to Microsoft Network Edge by streaming a set of packets to the nearest edge site and back for approximately 20s for a configured number of iterations. The tool reports:

    • Packet loss
    • Jitter
    • Round-trip latency
    • Reorder packet percentage

It runs on Windows 7 or later.

The tool uses the same real-time media technology as a Skype for Business Online client.

The results from using this tool can be used as part of a network assessment to determine if a network connection meets the targets

It’s a simple exe command line tool with a .config file

The results get output in a Tab Separated Values file (looks like my hotel wifi is not the best)

Nicely, there is then a results Analyser exe to do the maths for you :-)

Testing from my home fibre connection, works fine (better than the hotel wifi above :-) ):

Misc Notes:

  • You can change the Audio File that is played
  • You can change the file delimiter from a Tab to a comma, but the resultsanalyzer.exe will not parse the file unless you also manually define the delimiter
  • The Relay IP in the config file is an Anycast IP, it will route to the nearest ingress point on the Microsoft network from wherever you run the tool
