+# VPN Management
+
+## Overview
+
+A virtual private network (VPN) is a dedicated network established on a public network. On a VPN, the connection between any two nodes does not have an end-to-end physical link required by the traditional private network. Instead, user data is transmitted over a logical link because a VPN is a logical network deployed over the network platform (such as the Internet) provided by the public network service provider.
+
+> **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 [Traffic Management](../reference/apis/js-apis-net-vpn.md).
+
+The following describes the development procedure specific to each application scenario.
+
+## Available APIs
+
+For the complete list of APIs and example code, see [VPN Management](../reference/apis/js-apis-net-vpn.md).
+
+| Type| API| Description|
+| ---- | ---- | ---- |
+| ohos.net.vpn | setUp(config: VpnConfig, callback: AsyncCallback\<number\>): void | Establishes a VPN. This API uses an asynchronous callback to return the result.|
+| ohos.net.vpn | protect(socketFd: number, callback: AsyncCallback\<void\>): void | Enables VPN tunnel protection. This API uses an asynchronous callback to return the result.|
+| ohos.net.vpn | destroy(callback: AsyncCallback\<void\>): void | Destroys a VPN. This API uses an asynchronous callback to return the result.|
+
+## Starting a VPN
+
+1. Establish a VPN tunnel. The following uses the UDP tunnel as an example.
+2. Enable protection for the UDP tunnel.
+3. Establish a VPN.
+4. Process data of the virtual network interface card (vNIC), such as reading or writing data.
+5. Destroy the VPN.
+
+This example shows how to develop an application using native C++ code. For details, see [Simple Native C++ Example (ArkTS) (API9)] (https://gitee.com/openharmony/codelabs/tree/master/NativeAPI/NativeTemplateDemo).
+
+The sample application consists of two parts: JS code and C++ code.
+
+## JS Code
+The JS code is used to implement the service logic, such as creating a tunnel, establishing a VPN, enabling VPN protection, and destroying a VPN.
+
+```js

+  }
+
+  // 2. Enable protection for the UDP tunnel.
+  Protect() {
+    VpnConnection.protect(TunnelFd).then(function () {
+      console.info("vpn Protect Success.")

+  Destroy() {

+    VpnConnection.destroy().then(function () {
+      console.info("vpn Destroy Success.")
+    }).catch(function (err) {
+      console.info("vpn Destroy Failed " + JSON.stringify(err))
+    })
+  }
+
+  build() {
+    Row() {
+      Column() {
+        Text(this.message)
+          .fontSize(50)
+          .fontWeight(FontWeight.Bold)
