{{APIRef("WebRTC")}}

The **`perDscpPacketsSent`** property
of the {{domxref("RTCOutboundRtpStreamStats")}} dictionary is a record comprised of
key/value pairs in which each key is a string representation of a Differentiated
Services Code Point and the value is the number of packets sent for that DCSP.

> **Note:** Not all operating systems make data available on a per-DSCP
> basis, so this property shouldn't be relied upon on those systems.

## Syntax

```js
var perDscpPacketsSent = RTCOutboundRtpStreamStats.perDscpPacketsSent;
```

### Value

A record comprised of string/value pairs. Each key is the string representation of a
single Differentiated Services Code Point (DSCP)'s ID number.

> **Note:** Due to network bleaching and remapping, the numbers seen on
> this record are not necessarily going to match the values as they were when the data
> was sent.
