# Network GLB

Network Global Load Balancer (NGLB) is a networking solution that distributes Internet traffic across multiple servers located in different geographic regions. NGLB acts as a “traffic coordinator” on the Internet, ensuring that user requests are routed to the most appropriate server. This helps improve access speed, enhance reliability, and increase the scalability of applications.

#### Key Features of Network GLB:

* **Global Traffic Distribution:** NGLB distributes traffic across servers in multiple geographic locations, reducing latency and improving access speed for users worldwide.
* **Load Balancing:** NGLB evenly distributes incoming traffic among servers, preventing server overload and ensuring stable performance.
* **Geolocation routing:** NGLB identifies the geographic location of users and routes traffic to the nearest server to minimize latency.
* **Health check:** NGLB continuously monitors server health and automatically removes unhealthy servers from the traffic distribution process.
* **Failover:** If a server becomes unavailable, NGLB automatically redirects traffic to the remaining healthy servers, ensuring service availability.
* **Flexibility:** NGLB supports various load balancing algorithms (such as Round Robin and Least Connections), customizable routing policies, and multiple network protocols.
* **DNS Integration:** NGLB typically works closely with DNS systems to route requests to the appropriate server IP addresses.

## 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.vngcloud.vn/vng-cloud-document/glb/network-glb.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.
