Displaying Network and Building Information in Call Quality Dashboard (CQD) Online

In this link we describe the schema for network and building information and how to upload it to CQD Online. In this post I wanted to include a file with some sample information and add some additional information.

In an on-premises Lync/Skype for Business deployment, the clients can be internal or external depending on whether they connect via the Edge or not. The location is written to the quality report sent by the clients and can be used when querying QoEMetrics and CQD. However in an Skype for Business Online deployments all clients are by definition external, since they all connect via the Edge. That has the implication that all clients by default are seen as Outside in CQD Online, no matter if the client was actually connected on an internal corporate network.

When you work with call quality you are interested in knowing the location of a client and whether it was using a network you can manage or a network you can't manage. The assumption being that you can only improve networks you can manage. By uploading network and building information to CQD Online you can enable CQD to determine, if the client was connect to an internal corporate/managed network or to an external/unmanaged network.

CQD use the Network and the NetworkRange to correlate the Lync/Skype for Business clients IP address to a network. When the clients sends it quality report (VQReport) to the server, it contains the actual IP address and subnet mask in use. CQD takes these two, calculates the subnet and correlates it to networks by using Network and the NetworkRange. The NetworkRange is expressed using CIDR. For example if the clients IP address is, CQD will be able to correlate that to the Lyngby Office network given the sample attached. You would also be able to see that this would fall in the Inside bucket, since the Lyngby Office network has InsideCorp = 1. Please note that if you use supernetting, you will have to specify Network and NetworkRange as your clients are configured, i.e. if you use as a supernet, but your clients see you need to have a record for in your building information.

The file format is a tab separated text file (TSV) as described in the link above. The easiest way to generate the file is to use Excel. You can add a header line with the fields from the schema and then just add rows with the information. When you're done, save the information as "Text (tab delimited)" and using the extension *.tsv from within Excel. Remember to remove the header line from the resulting file before you upload it to CQD.

When you upload the network information you specify a date range. You can look at the date range as the validity period of the network information.

CQD will start processing the information as soon as the upload happens. You can monitor the progress by using the Tenant Health option on the gear icon. This will show you how far CQD has come in the processing. An example is shown below

To validate that CQD has used the uploaded information, look at the Server-Client Summary Report. You should now see information in the Wired Inside and/or Wifi Inside categories, as shown in the example below:
