## 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("received message--:" + str);
console.log("received address--:" + value.remoteInfo.address);
console.log("received family--:" + value.remoteInfo.family);
console.log("received port--:" + value.remoteInfo.port);

client.send({data: 'Hello, client!'}, err => {
if (err) {
console.log('send fail');
return;
}
console.log('send success');
});
// Close the connection between the client and the server.
client.close(err => {
if (err) {
console.log('close fail');
return;
}
console.log('close success');
});
// Unsubscribe from events of the TCPSocketConnection object.

### 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.

#### Rule: Name an SDK in the format of **domain\_keyword&lt;*other information 1*\_*other information 2*\_…&gt;\_sdk.so**. #### Rule: Name an SDK in the format of **domain_keyword<_other information 1_other information 2_...>_sdk.so**.
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. 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 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**.
#### Rule: Name a plug-in in the format of **domain\_keyword&lt;*other information 1*\_*other information 2*\_…&gt;.so**. #### Rule: Name a plug-in in the format of **domain_keyword<_other information 1_other information 2_...>.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. 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 NNRt architecture consists of three layers: AI applications at the application layer, AI inference framework and NNRt at the system layer, and device services at the chip layer. To use a dedicated acceleration chip model for inference, an AI application needs to call the dedicated acceleration chip at the bottom layer through the AI inference framework and NNRt. NNRt is responsible for adapting to various dedicated acceleration chips at the bottom layer. It opens standard and unified HDIs for various chips to access the OpenHarmony ecosystem. The NNRt architecture consists of three layers: AI applications at the application layer, AI inference framework and NNRt at the system layer, and device services at the chip layer.

### Application Scenario ### Application Scenario
Suppose you are connecting an AI acceleration chip, for example, RK3568, to NNRt. The following describes how to connect the RK3568 chip to NNRt through the HDI to implement AI model inference. Suppose you are connecting an AI acceleration chip, for example, RK3568, to NNRt. The following exemplifies how to connect the RK3568 chip to NNRt through HDI V2.0 to implement AI model inference. The process is similar for HDI V1.0.
> **NOTE**<br>In this application scenario, the connection of the RK3568 chip to NNRt is implemented by utilizing the CPU operator of MindSpore Lite, instead of writing the CPU driver. This is the reason why the following development procedure depends on the dynamic library and header file of MindSpore Lite. In practice, the development does not depend on any library or header file of MindSpore Lite. > **NOTE**<br>In this tutorial, the purpose of connecting the RK3568 chip to NNRt is to utilize the runtime and CPU operators of MindSpore Lite, instead of implementing the CPU driver. Therefore, the RK3568 chip depends on the dynamic libraries and header files of MindSpore Lite. In practice, the RK3568 chip does not depend on any library or header file of MindSpore Lite.

### Development Procedure ### Development Procedure
The following uses the RK3568 chip as an example to describe the development procedure.
To connect the acceleration chip to NNRt, perform the development procedure below.
#### Generating the HDI Header File #### Generating the HDI Header File
Download the OpenHarmony source code from the open source community, build the `drivers_interface` component, and generate the HDI header file. Download the OpenHarmony source code from the open source community, build the `drivers_interface` component, and generate the HDI header file.
1. [Download the source code](../get-code/sourcecode-acquire.md). 1. [Download the source code](../get-code/sourcecode-acquire.md).
2. Build the IDL file of the HDI. 2. Go to the root directory of OpenHarmony source code, and compile the IDL API file of NNRt.
```shell ```shell
./build.sh --product-name productname –ccache --build-target drivers_interface_nnrt ./build.sh --product-name rk3568 –ccache --build-target drivers_interface_nnrt
``` ```
> **NOTE**<br>**productname** indicates the product name. In this example, the product name is **RK3568**.
When the build is complete, the HDI header file is generated in `out/rk3568/gen/drivers/interface/nnrt`. The default programming language is C++. To generate a header file for the C programming language, run the following command to set the `language` field in the `drivers/interface/nnrt/v1_0/BUILD.gn` file before starting the build: After the compilation is complete, an HDI header file of the C++ language is generated in the `out/rk3568/gen/drivers/interface/nnrt/v2_0` directory. To generate a header file of the C language, run the following command to set the language field in the `drivers/interface/nnrt/v2_0/BUILD.gn` file before starting compilation:

10. Configure access permissions because SELinux uses the trustlist access permission mechanism. Upon service startup, run the `dmesg` command to view the AVC alarm,
which provides a list of missing permissions. For details about the SELinux configuration, see [security_selinux] (https://gitee.com/openharmony/security_selinux/blob/master/README-en.md).
```shell
hdc_std shell
dmesg | grep nnrt

### Commissioning and Verification ### Commissioning and Verification
On completion of service development, you can use XTS to verify its basic functions and compatibility. On completion of service development, you can use XTS to verify its basic functions and compatibility. The operation procedure is as follows:
1. Build the **hats** test cases of NNRt in the `test/xts/hats/hdf/nnrt` directory. 1. Compile the **hats** test cases of NNRt in the `test/xts/hats/ai/nnrt/hdi` directory.
```shell ```shell
# Go to the hats directory. # Go to the hats directory.
cd test/xts/hats cd test/xts/hats
# Build the hats test cases. # Compile the `hats` test cases.
./build.sh suite=hats system_size=standard --product-name rk3568 ./build.sh suite=hats system_size=standard product_name=rk3568
# Return to the root directory. # Return to the root directory.
cd - cd -
``` ```
The hats test cases are exported to `out/rk3568/suites/hats/testcases/HatsHdfNnrtFunctionTest` in the relative code root directory. The test case executable file `HatsHdfNnrtFunctionTest` is exported to the `out/rk3568/suites/hats/testcases/` directory.
2. Push the test cases to the device. 2. Push the test case executable file to the `/data/local/tmp/` directory of the RK3568 device.
```shell ```shell
# Push the executable file of test cases to the device. In this example, the executable file is HatsHdfNnrtFunctionTest. # Push the test case executable file to the device. In this example, the executable file is HatsHdfNnrtFunctionTest.
