# Network Connection Management
## Introduction
The Network Connection Management module provides basic network management capabilities, including management of Wi-Fi/cellular/Ethernet connection priorities, network quality evaluation, subscription to network connection status changes, query of network connection information, and DNS resolution.
> **NOTE**
> To maximize the application running efficiency, most API calls are called asynchronously in callback or promise mode. The following code examples use the callback mode. For details about the APIs, see [sms API Reference](../reference/apis/js-apis-net-connection.md).
## Basic Concepts
- Producer: a provider of data networks, such as Wi-Fi, cellular, and Ethernet.
- Consumer: a user of data networks, for example, an application or a system service.
- Network probe: a mechanism used to detect the network availability to prevent the switch from an available network to an unavailable network. The probe type can be binding network detection, DNS detection, HTTP detection, or HTTPS detection.
- Network selection: a mechanism used to select the optimal network when multiple networks coexist. It is triggered when the network status, network information, or network quality evaluation score changes.

# Ethernet Connection
## Introduction
The Ethernet Connection module allows a device to access the Internet through a network cable.
After a device is connected to the Ethernet through a network cable, the device can obtain a series of network attributes, such as the dynamically allocated IP address, subnet mask, gateway, and DNS. You can manually configure and obtain the network attributes of the device in static mode.

## Subscribes the status change of network device interfaces.
### How to Develop
1. Import the **ethernet** namespace from **@ohos.net.ethernet**.
2. Call the **on()** method to subscribe to **interfaceStateChange** events. It is up to you whether to listen for **interfaceStateChange** events.
3. Check whether an **interfaceStateChange** event is triggered when the interface state changes.
4. Call the **off()** method to unsubscribe from **interfaceStateChange** events.
```js
// Import the ethernet namespace from @ohos.net.ethernet.
import ethernet from '@ohos.net.ethernet'
// Subscribe to interfaceStateChange events.
ethernet.on('interfaceStateChange', ((data) => {
console.log(JSON.stringify(data));
}));
// Unsubscribe from interfaceStateChange events.
ethernet.off('interfaceStateChange');
```
# Network Sharing
## Introduction
The Network Sharing module allows you to share your device's Internet connection with other connected devices by means of Wi-Fi hotspot, Bluetooth, and USB sharing. It also allows you to query the network sharing state and shared mobile data volume.
> **NOTE**
> To maximize the application running efficiency, most API calls are called asynchronously in callback or promise mode. The following code examples use the callback mode. For details about the APIs, see [sms API Reference](../reference/apis/js-apis-net-sharing.md).
## Basic Concepts
- Wi-Fi sharing: Shares the network through a Wi-Fi hotspot.
- Bluetooth sharing: Shares the network through Bluetooth.
- USB tethering: Shares the network using a USB flash drive.
- Wi-Fi sharing: Shares the network through a Wi-Fi hotspot.
- Bluetooth sharing: Shares the network through Bluetooth.
- USB tethering: Shares the network using a USB flash drive.
## **Constraints**
- Programming language: C++ and JS
- System: Linux kernel
- The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.

# WebSocket Connection
## Use Cases
## When to Use
You can use WebSocket to establish a bidirectional connection between a server and a client. Before doing this, you need to use the **createWebSocket()** API to create a **WebSocket** object and then use the **connect()** API to connect to the server. If the connection is successful, the client will receive a callback of the **open** event. Then, the client can communicate with the server using the **send()** API. When the server sends a message to the client, the client will receive a callback of the **message** event. If the client no longer needs this connection, it can call the **close()** API to disconnect from the server. Then, the client will receive a callback of the **close** event.
If an error occurs in any of the preceding processes, the client will receive a callback of the **error** event.
## Available APIs
The WebSocket connection function is mainly implemented by the WebSocket module. To use related APIs, you must declare the **ohos.permission.INTERNET** permission. The following table describes the related APIs.
| API | Description |
| API| Description|
| -------- | -------- |
| createWebSocket() | Creates a WebSocket connection. |
| connect() | Establishes a WebSocket connection to a given URL. |
| send() | Sends data through the WebSocket connection. |
| close() | Closes a WebSocket connection. |
| on(type: 'open') | Enables listening for **open** events of a WebSocket connection. |
| off(type: 'open') | Disables listening for **open** events of a WebSocket connection. |
| on(type: 'message') | Enables listening for **message** events of a WebSocket connection. |
| off(type: 'message') | Disables listening for **message** events of a WebSocket connection. |
| on(type: 'close') | Enables listening for **close** events of a WebSocket connection. |
| off(type: 'close') | Disables listening for **close** events of a WebSocket connection. |
| on(type: 'error') | Enables listening for **error** events of a WebSocket connection. |
| off(type: 'error') | Disables listening for **error** events of a WebSocket connection. |
| createWebSocket() | Creates a WebSocket connection.|
| connect() | Establishes a WebSocket connection to a given URL.|
| send() | Sends data through the WebSocket connection.|
| close() | Closes a WebSocket connection.|

## How to Develop
1. Import the required WebSocket module.
1. Import the required webSocket module.
2. Create a **WebSocket** object.
3. (Optional) Subscribe to WebSocket open, message, close, and error events.
3. (Optional) Subscribe to WebSocket **open**, **message**, **close**, and **error** events.
4. Establish a WebSocket connection to a given URL.
5. Close the WebSocket connection if it is no longer needed.

You can use WebSocket to establish a bidirectional connection between a server and a client. Before doing this, you need to use the [createWebSocket](#websocketcreatewebsocket) API to create a [WebSocket](#websocket) object and then use the [connect](#connect) API to connect to the server. If the connection is successful, the client will receive a callback of the [open](#onopen) event. Then, the client can communicate with the server using the [send](#send) API. When the server sends a message to the client, the client will receive a callback of the [message](#onmessage) event. If the client no longer needs this connection, it can call the [close](#close) API to disconnect from the server. Then, the client will receive a callback of the [close](#onclose) event.
