## Implementing Data Transmission over TCP Socket Server Connections
### How to Develop
The TCP socket server connection process is described as follows:
1. Import the required **socket** module.
2. Create a TCP socket server connection. A **TCPSocketServer** object is returned.
3. Bind the local IP address and port, and listen for and accept TCP socket connections established over the socket.
4. Subscribe to **connect** events of the **TCPSocketServer** object to listen for client connection status changes.
5. Set up a connection between the client and the server. A **TCPSocketConnection** object is returned.
6. Subscribe to events of the **TCPSocketConnection** object, and send data to the client through the **TCPSocketConnection** object.
7. Close the connection between the client and the server.
8. Unsubscribe from events of the **TCPSocketConnection** and **TCPSocketServer** objects.
```js
import socket from '@ohos.net.socket'
// Create a TCP socket server connection. A TCPSocketServer object is returned.
let tcpServer = socket.constructTCPSocketServerInstance();
// Bind the local IP address and port number for listening.
tcpServer.listen({ address: "192.168.xx.xxx", port: xxxx, family: 1 }, err => {
if (err) {
console.log("listen fail");
return;
}
console.log("listen success");
})
// Subscribe to connect events of the TCPSocketServer object.
tcpServer.on('connect', function(client) {
// Subscribe to events of the TCPSocketConnection object.
client.on('close', () => {
console.log("on close success");
});
client.on('message', function(value) {
let buffer = value.message;
let dataView = new DataView(buffer);
let str = "";
for (let i = 0; i < dataView.byteLength; ++i) {
str += String.fromCharCode(dataView.getUint8(i));

console.log('send fail');
return;
}
console.log('send success');
});
// Close the connection between the client and the server.
client.close(err => {

console.log('close fail');

### Introduction ### Introduction
The AI subsystem is the part of OpenHarmony that provides native distributed AI capabilities. At the heart of the subsystem is a unified AI engine framework, which implements quick integration of AI algorithm plug-ins. The AI subsystem is the part of OpenHarmony that provides native distributed AI capabilities. At the heart of the subsystem is a unified AI engine framework, which implements quick integration of AI algorithm plug-ins.
The framework consists of the plug-in management, module management, and communication management modules, fulfilling lifecycle management and on-demand deployment of AI algorithms. Specifically, plug-in management implements lifecycle management, on-demand deployment, and quick integration of AI algorithm plug-ins; module management implements task scheduling and client instance management; communication management manages inter-process communication (IPC) between the client and server and data transmission between the AI engine and plug-ins. Under this framework, AI algorithm APIs will be standardized to facilitate distributed calling of AI capabilities. In addition, unified inference APIs will be provided to adapt to different inference framework hierarchies.

### Code Management ### Code Management
The AI engine framework consists of three modules: **client**, **server**, and **common**. The client module provides the server connection management function. The SDK needs to encapsulate and call the public APIs provided by the client in the algorithm's external APIs. The server module provides functions such as plug-in loading and task management. Plug-ins are integrated using the plug-in APIs provided by the server. The common module provides platform-related operation methods, engine protocols, and tool classes for other modules.

The AI subsystem exposes its capabilities through external APIs of SDKs. According to API management requirements of OpenHarmony, store all external APIs of SDKs in the **interfaces/kits** directory of the subsystem. Currently, the external APIs of plug-ins of the AI subsystem are stored in the **//foundation/ai/engine/interfaces/kits** directory. You can add a sub-directory for each newly added plug-in in this directory.

You are advised to use the commonly known abbreviations for domains. For example, use **cv** for image and video, **asr** for voice recognition, and **translation** for text translation. Add one if there is no available abbreviation for a domain. Use keywords that accurately describe the algorithm capability of the plug-in. For example, use **keyword\_spotting** for wakeup keyword spotting (KWS). Add other information, such as the supported chip type and applicable region, between **keyword** and **sdk**, with each of them separated by an underscore (\_). Note that the name of a SDK must end with **\_sdk**. You are advised to use the commonly known abbreviations for domains.

Note that the name of an SDK must end with **\_sdk**.
For example, if the SDK for the KWS plug-in supports only the Kirin 9000 chipset and is applicable only in China, then name the SDK as follows: **asr\_keyword\_spotting\_kirin9000\_china\_sdk.so**. For example, if the SDK for the KWS plug-in supports only the Kirin 9000 chipset and is applicable only in China, then name the SDK as follows: **asr\_keyword\_spotting\_kirin9000\_china\_sdk.so**.

There is a one-to-one mapping between plug-ins and SDKs. Therefore, the definitions and requirements of terms such as the domain, keyword, and other information in plug-in names are the same as those in SDK names. The only difference is that the name of the SDK ends with **\_sdk** additionally. For example, if the plug-in is named **asr\_keyword\_spotting.so**, the corresponding SDK is named **asr\_keyword\_spotting\_sdk.so**. There is a one-to-one mapping between plug-ins and SDKs.
