+使用gRPC接口，Client端可以在Win/Linux/MacOS平台上调用不同语言。gRPC 接口实现结构如下：
 
-## 与bRPC接口对比
+![](https://github.com/PaddlePaddle/Serving/blob/develop/doc/grpc_impl.png)
 
-1. gRPC Server 端 `load_model_config` 函数添加 `client_config_path` 参数：
+## 1.与bRPC接口对比
 
-   ```python
+#### 1.1 服务端对比
+
+* gRPC Server 端 `load_model_config` 函数添加 `client_config_path` 参数：
+
+   ```
    def load_model_config(self, server_config_paths, client_config_path=None)
    ```
+    在一些例子中 bRPC Server 端与 bRPC Client 端的配置文件可能不同（如 在cube local 中，Client 端的数据先交给 cube，经过 cube 处理后再交给预测库），此时 gRPC Server 端需要手动设置 gRPC Client 端的配置`client_config_path`。
+    **`client_config_path` 默认为 `<server_config_path>/serving_server_conf.prototxt`。**
 
-   在一些例子中 bRPC Server 端与 bRPC Client 端的配置文件可能是不同的（如 cube local 例子中，Client 端的数据先交给 cube，经过 cube 处理后再交给预测库），所以 gRPC Server 端需要获取 gRPC Client 端的配置；同时为了取消 gRPC Client 端手动加载配置文件的过程，所以设计 gRPC Server 端同时加载两个配置文件。`client_config_path` 默认为 `<server_config_path>/serving_server_conf.prototxt`。
+#### 1.2 客服端对比
 
-2. gRPC Client 端取消 `load_client_config` 步骤：
+* gRPC Client 端取消 `load_client_config` 步骤：
 
    在 `connect` 步骤通过 RPC 获取相应的 prototxt（从任意一个 endpoint 获取即可）。
 
-3. gRPC Client 需要通过 RPC 方式设置 timeout 时间（调用形式与 bRPC Client保持一致）
+* gRPC Client 需要通过 RPC 方式设置 timeout 时间（调用形式与 bRPC Client保持一致）
 
    因为 bRPC Client 在 `connect` 后无法更改 timeout 时间，所以当 gRPC Server 收到变更 timeout 的调用请求时会重新创建 bRPC Client 实例以变更 bRPC Client timeout时间，同时 gRPC Client 会设置 gRPC 的 deadline 时间。
 
    **注意，设置 timeout 接口和 Inference 接口不能同时调用（非线程安全），出于性能考虑暂时不加锁。**
 
-4. gRPC Client 端 `predict` 函数添加 `asyn` 和 `is_python` 参数：
+* gRPC Client 端 `predict` 函数添加 `asyn` 和 `is_python` 参数：
 
-   ```python
+   ```
    def predict(self, feed, fetch, need_variant_tag=False, asyn=False, is_python=True)
    ```
 
-   其中，`asyn` 为异步调用选项。当 `asyn=True` 时为异步调用，返回 `MultiLangPredictFuture` 对象，通过 `MultiLangPredictFuture.result()` 阻塞获取预测值；当 `asyn=Fasle` 为同步调用。
+1.    `asyn` 为异步调用选项。当 `asyn=True` 时为异步调用，返回 `MultiLangPredictFuture` 对象，通过 `MultiLangPredictFuture.result()` 阻塞获取预测值；当 `asyn=Fasle` 为同步调用。
+
+2.    `is_python` 为 proto 格式选项。当 `is_python=True` 时，基于 numpy bytes 格式进行数据传输，目前只适用于 Python；当 `is_python=False` 时，以普通数据格式传输，更加通用。使用 numpy bytes 格式传输耗时比普通数据格式小很多（详见 [#654](https://github.com/PaddlePaddle/Serving/pull/654)）。
+
+#### 1.3 其他
+
+* 异常处理：当 gRPC Server 端的 bRPC Client 预测失败（返回 `None`）时，gRPC Client 端同样返回None。其他 gRPC 异常会在 Client 内部捕获，并在返回的 fetch_map 中添加一个 "status_code" 字段来区分是否预测正常（参考 timeout 样例）。
+
+* 由于 gRPC 只支持 pick_first 和 round_robin 负载均衡策略，ABTEST 特性还未打齐。
+
+* 系统兼容性：
+    * [x]  CentOS
+    * [x]  macOS
+    * [x]  Windows
+
+* 已经支持的客户端语言：
+
+   -  Python
+   -  Java
+   -  Go
+   
+   
+## 2.示例：线性回归预测服务
+
+以下是采用gRPC实现的关于线性回归预测的一个示例，具体代码详见此[链接](https://github.com/PaddlePaddle/Serving/tree/develop/python/examples/grpc_impl_example/fit_a_line)
+#### 获取数据
+
+```shell
+sh get_data.sh
+```
+
+#### 开启 gRPC 服务端
+
+``` shell
+python test_server.py uci_housing_model/
+```
+
+也可以通过下面的一行代码开启默认 gRPC 服务：
+
+```shell
+python -m paddle_serving_server.serve --model uci_housing_model --thread 10 --port 9393 --use_multilang
+```
+注：--use_multilang参数用来启用多语言客户端
+
+### 客户端预测
+
+#### 同步预测
+
+``` shell
+python test_sync_client.py
+```
+
+#### 异步预测
+
+``` shell
+python test_asyn_client.py
+```
+
+#### Batch 预测
+
+``` shell
+python test_batch_client.py
+```
 
-   `is_python` 为 proto 格式选项。当 `is_python=True` 时，基于 numpy bytes 格式进行数据传输，目前只适用于 Python；当 `is_python=False` 时，以普通数据格式传输，更加通用。使用 numpy bytes 格式传输耗时比普通数据格式小很多（详见 [#654](https://github.com/PaddlePaddle/Serving/pull/654)）。
+#### 通用 pb 预测
 
-5. 异常处理：当 gRPC Server 端的 bRPC Client 预测失败（返回 `None`）时，gRPC Client 端同样返回None。其他 gRPC 异常会在 Client 内部捕获，并在返回的 fetch_map 中添加一个 "status_code" 字段来区分是否预测正常（参考 timeout 样例）。
+``` shell
+python test_general_pb_client.py
+```
 
-6. 由于 gRPC 只支持 pick_first 和 round_robin 负载均衡策略，ABTEST 特性还未打齐。
+#### 预测超时
 
-7. 经测试，gRPC 版本可以在 Windows、macOS 平台使用。
+``` shell
+python test_timeout_client.py
+```
 
-8. 计划支持的客户端语言：
+#### List 输入
 
-   - [x] Python
-   - [ ] Java
-   - [ ] Go
-   - [ ] JavaScript
+``` shell
+python test_list_input_client.py
+```
