篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Android 移植iperf3.13 测试网络相关的知识,希望对你有一定的参考价值。

iperf,测试网络性能的,不同于 webrtc里面的gcc 算法预估网络带宽,iperf是实际占用网络来传输数据测量实际的网络性能。

官网:https://iperf.fr/
官方就有 android 的下载 https://iperf.fr/iperf-download.php#android, 但是看起来要访问 play.google. 墙。急用,怎么自己拿源码来ndk 编译一下。
1. 最适配的方式,应该是用 configure + make, configure来配置ndk编译器。 (ubuntu环境下) 没有环境,不想太折腾
2. 在AndroidStudio 上用cmake 编译
3. 还是用比较熟悉的 Android.mk , 在AS中编译
 

目录

一:下载源码

 二:AS 创建一个空的demo,src/main 目录下建一个jni, 把源码解压到这里, 然后编写 Android.mk 来编译。(如果直接使用ndk-build 命令,就不需要AS了。)

  在app 的build.gradle中手动指定Android.mk 文件位置,使用的ndk版本,以及要编译的平台

Android.mk

对源码需要做一点头文件的修改

1. 在src 中加上 iperf_config.h

2. src 目录下 version.h    同上,来源为version.h.in

3.修改源码里面一个 字符串,临时文件的路径

最后,build

1. 测试带宽

 2. 测试udp 丢包


一:下载源码

发布的只有3.1.3 iPerf - Download iPerf3 and original iPerf pre-compiled binaries

 二:AS 创建一个空的demo,src/main 目录下建一个jni, 把源码解压到这里, 然后编写 Android.mk 来编译。(如果直接使用ndk-build 命令,就不需要AS了。)


  在app 的build.gradle中手动指定Android.mk 文件位置,使用的ndk版本,以及要编译的平台

对源码需要做一点头文件的修改

本来这些头文件是 configure 命令自动添加上去的,我们没有configure,需要自己动手补上。

1. 在src 中加上 iperf_config.h

(来源是源码中的 iperf_config.h.in,  configure命令以这个为输入,定义了一些宏, 不确定的话,直接把这个iperf3搞到ubuntu上,运行一下./configure  可以得到一版,然参考修改) 可直接参考:
iperf_config.h

/* src/iperf_config.h.in.  Generated from configure.ac by autoheader.  */

/* Define to 1 if you have the `cpuset_setaffinity' function. */
#undef HAVE_CPUSET_SETAFFINITY

/* Have CPU affinity support. */
#undef HAVE_CPU_AFFINITY

/* Define to 1 if you have the <dlfcn.h> header file. */
#undef HAVE_DLFCN_H

/* Have IPv6 flowlabel support. */
#undef HAVE_FLOWLABEL

#undef HAVE_SCHED_SETAFFINITY

/* Have SCTP support. */
#undef HAVE_SCTP

/* Define to 1 if you have the `sendfile' function. */
#undef HAVE_SENDFILE

/* Have SO_MAX_PACING_RATE sockopt. */
#undef HAVE_SO_MAX_PACING_RATE

/* Define to 1 if you have the <stdint.h> header file. */
#undef HAVE_STDINT_H

/* Define to 1 if you have the <stdlib.h> header file. */
#undef HAVE_STDLIB_H

/* Define to 1 if you have the <strings.h> header file. */
#undef HAVE_STRINGS_H

/* Define to 1 if you have the <string.h> header file. */
#undef HAVE_STRING_H

/* Define to 1 if the system has the type `struct sctp_assoc_value'. */
#undef HAVE_STRUCT_SCTP_ASSOC_VALUE

/* Define to 1 if you have the <sys/socket.h> header file. */
#undef HAVE_SYS_SOCKET_H

/* Define to 1 if you have the <sys/stat.h> header file. */
#undef HAVE_SYS_STAT_H

/* Define to 1 if you have the <sys/types.h> header file. */
#undef HAVE_SYS_TYPES_H

/* Have TCP_CONGESTION sockopt. */
#undef HAVE_TCP_CONGESTION

/* Define to 1 if you have the <unistd.h> header file. */
#undef HAVE_UNISTD_H

/* Define to the sub-directory where libtool stores uninstalled libraries. */
#undef LT_OBJDIR

/* Name of package */
#define PACKAGE "iperf"

/* Define to the address where bug reports for this package should be sent. */
#define PACKAGE_BUGREPORT "https://github.com/esnet/iperf"

/* Define to the full name of this package. */
#define PACKAGE_NAME "iperf"

/* Define to the full name and version of this package. */
#define PACKAGE_STRING "iperf 3.1.3"

/* Define to the one symbol short name of this package. */
#define PACKAGE_TARNAME "iperf"

/* Define to the home page for this package. */
#define PACKAGE_URL "http://software.es.net/iperf/"

/* Define to the version of this package. */
#define PACKAGE_VERSION "3.1.3"

/* Define to 1 if you have the ANSI C header files. */
#define STDC_HEADERS 1

/* Version number of package */
#define VERSION "3.1.3"


2. src 目录下 version.h    同上,来源为version.h.in

#define IPERF_VERSION "3.1.3"

3.修改源码里面一个 字符串,临时文件的路径

iperf_aip.c::

 /tmp/ 这个是linux路径,android 上没有,直接改为 /data/ 或者就是当前运行目录。

最后,build

在app\\build\\intermediates\\ndkBuild\\debug\\obj\\local\\arm64-v8a  得到可执行文件, push 到/data/xx上去运行。

附上测试命令:

1. 测试带宽

服务端:#iperf3 -s -p 5001
                -s 表示作为服务端, -p 指定端口号

        
客户端:#iperf3 -c 127.0.0.1(服务器IP) -P 4 -t 30 -i 2 -p 5001
                -c 表示作为客户端, 后面跟服务端ip,  -P (大写) 表示process, 同时并发任务数,这里是4,  -t 表示测试持续时间,单位秒。   -i 表示每隔2秒报一次结果。  -p 端口号

 2. 测试udp 丢包

(udp无连接,发快网络带宽不够导致丢包,所以测udp在限制带宽的情况下丢包率)
服务端:#iperf3 -s -p 5001
客户端:
 #iperf3 -u -c 192.168.43.129 -p 8989 -b 100M -t 30
                -u 指定使用udp, -c 表示作为客户端   -b 限制在100Mbit
