# NDI Proxy and bandwidth optimization

By default, an NDI Sender has the capability to generate two types of streams: a full-quality stream and a proxy stream. A receiver can readily activate the [**proxy stream**](https://docs.ndi.video/all/developing-with-ndi/sdk/ndi-recv). A simple way to visualize a proxy stream is by utilizing NDI Studio Monitor and enabling the Low Bandwidth mode within the Video settings menu.

The Proxy stream serves as a means for an application to enhance the efficiency of NDI distribution across the network. For instance, an NDI-based Video Mixer can leverage the proxy stream for sources that are intended for use in a preview monitor rather than an actual output. Then, when a source is transitioned to an output, the application can seamlessly switch from the proxy stream to the full bandwidth stream.

This approach empowers receivers to effectively manage a more significant number of NDI sources while utilizing less network bandwidth.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ndi.video/all/getting-started/white-paper/bandwidth/ndi-proxy-and-bandwidth-optimization.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
