# Network Rate Limit

Network Rate Limit controls how quickly content is delivered to clients by applying a transfer speed limit after a configurable amount of data has been transferred. 

{% hint style="success" %}
This feature can be used alongside [Rate Limiting](/products/security/rate-limiting.md) to control both request volume and content delivery speed.
{% endhint %}

This feature can be used to manage bandwidth consumption and control the delivery rate of large files or streaming content.

### How Network Rate Limit Works

Network Rate Limit is configured using two parameters:

<table data-header-hidden><thead><tr><th width="236.4000244140625"></th><th></th></tr></thead><tbody><tr><td>Parameter</td><td>Description</td></tr><tr><td>Rate Limit</td><td>Maximum transfer speed applied after the threshold is reached.</td></tr><tr><td>Threshold</td><td>Amount of data transferred before the rate limit is enforced.</td></tr></tbody></table>

Content is delivered at normal speed until the configured threshold is reached. Once the threshold is exceeded, the CDN limits the transfer rate according to the configured value.

### Configuration

Enable **Network Rate Limit** and configure the following settings:

#### Rate Limit

Defines the maximum transfer speed applied to content delivery after throttling begins.

Supported units:

* KB/s
* MB/s

#### Threshold

Defines how much data can be transferred before the configured rate limit takes effect.

Supported units:

* KB
* MB

### Example

The following configuration:

* Rate Limit: **1 MB/s**
* Threshold: **512 MB**

Allows the first 512 MB of content to be delivered without restriction. After 512 MB has been transferred, the CDN limits delivery speed to 1 MB/s.

### Common Use Cases

{% hint style="info" %}
Network Rate Limit can also be combined with [Geo Blocking](/products/security/geoblocking.md), [IP Restriction](/products/security/ip-restriction.md), and Security Token to apply bandwidth controls only to specific audiences or protected content.
{% endhint %}

#### Large File Delivery

Prevent excessive bandwidth consumption when distributing large software packages, backups, or downloadable assets.

#### Media Distribution

Allow video playback or file downloads to start quickly while controlling sustained transfer rates for long-running sessions.

#### Bandwidth Management

Reduce the impact of high-volume transfers on overall resource consumption.

### Important Notes

* Rate limiting is enforced at the CDN edge.
* Content is delivered at full speed until the configured threshold is reached.
* Lower rate limits may increase download completion times.
* Threshold values should be configured carefully to balance user experience and bandwidth control.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://clients.medianova.com/products/security/network-rate-limit.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.
