Network Assessment Tool-Skype for Business online

We are in cloud era and moving most of technologies into cloud such as Exchange Online, Lync Online aka Skype For Business, Share Point etc. before moving to cloud we have to check some pre-requisite task such as required Network, System Security etc.

In series of assessment tool Microsoft have released a Skype for Business Network Assessment Tool and it is free for public download from here

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

Installing and running the tool

First download the tool from here, it will be as zip file you need to unzip the files to directory



We need to use Windows Power Shell the run the tool from any of the computer such as Windows 7 etc.

Before we run this we have to have familiar with the configuration file that sets up the options for the tool to run.

The configuration file is called “NetworkAssessmentTool.exe.config” and is located in the same directory as the other files. You can edit the file if required. The defaults are as shown below:



Now time to run the tool with using the Power Shell command

now you can check the output from here :



The key configuration components are explained in the following table:

Configuration
Description
If Not Specified
Relay.IP
IP address to reach the relay server. MUST be a valid IP address string.
Tool will fail.
Relay.UDPPort
UDP port to reach the relay server for relay allocations. MAY be omitted if the user wishes to test TCP allocations only. If both UDP and TCP are configured, UDP will be preferred if the relay is reachable via UDP.
If UDP and TCP are not specified, tool will fail. Otherwise, allocate on TCP only.
Relay.TCPPort
TCP port to reach the relay server for relay allocations. MAY be omitted if the user wishes to test UDP allocations only.
If UDP and TCP are not specified, tool will fail. Otherwise, allocate on UDP only.
WMAFilePath

Number of audio calls to make. These will be made serially (no concurrency).
Takes value of 1.
ResultsFilePath
Location to output the results to. This is typically a tsv or csv. The delimiter is specified by the “Delimiter” setting. The first line of the output describes what each column is.
Results will not be output to a file.
Delimiter
For the output file in “ResultsFilePath” (if specified), this is the separator for each column in the output file.
Takes value of .
IntervalInSeconds
Time to wait between consecutive calls.
Takes value of 5.0s.
WMAOutputFilePath
Path to where the audio received will be written.  If file exists it will be overwritten
Tool will fail.

Configuration

Following is the sample for configuration of the tool:

This the concludes a summary of installing and running the network requirements tool for Skype Online, hope it will help you to analyze the Network requirement for Skype for Business.
