java 网络检测工具 java测网速源码

I'm Shendi

最近搞了台服务器,于是就想测试一下网速(与用户之间的速度)

上传速度 客户端发数据给服务端,服务端接收到多少字节就是速度

下载速度 服务端发数据给客户端,客户端接收到多少字节就是速度

避免偏差过大,两个步骤执行时间都为10秒

代码如下

package shendi.test.dos;

import java.io.InputStream;
import java.io.OutputStream;
import java.net.ServerSocket;
import java.net.Socket;

	public volatile static boolean upYes;

				}
				System.out.println("下载速度:" + (downNum / 10 >> 10) + "kb/s");
				socket.close();
			} catch (Exception e) {
