如何安装？

可以参考官方说明文档，一步步带你安装、了解特性、开始测试

编译好的版本

可以直接在 Github 下载稳定编译好的版本：Github 版本发布页

自己构建

环境和背景条件要求

官方是支持在 Linux和Cygwin(Windows平台上运行的UNIX模拟环境)下可使用，其他环境未经测试，可能可以使用。

此外你需要具备：

• C++ 编译器
• curses or ncurses library
• For TLS 支持: OpenSSL >= 0.9.8 or WolfSSL >= 3.15.0
• For pcap play 支持: libpcap and libnet
• For SCTP 支持: lksctp-tools
• For distributed pauses: Gnu Scientific Libraries

常规如果你不需要支持TLS/SCTP/PCAP 的话，只需要

tar -xvzf sipp-xxx.tar
cd sipp
cmake .
make

4个步骤就可以开启编译

如何使用？

包含的参数属性很多：

Default is 1 second and defaultunit is milliseconds.  This allows you to have n calls every m milliseconds(by using -r n -rp m).Example: -r 7 -rp 2000 ==> 7 calls every 2 seconds.-r 10 -rp 5s => 10 calls every 5 seconds.-rate_scale      : Control the units for the '+', '-', '*', and '/' keys.-rate_increase   : Specify the rate increase every -rate_interval units (default is seconds).

The passed IPaddress depends on the 3PCC role.- When the first twin command is 'sendCmd' then this is the address of theremote twin socket.  SIPp will try to connect to this address:port to sendthe twin command (This instance must be started after all other 3PCCscenarios).Example: 3PCC-C-A scenario.- When the first twin command is 'recvCmd' then this is the address of thelocal twin socket. SIPp will open this address:port to listen for twincommand.Example: 3PCC-C-B scenario.-master          : 3pcc extended mode: indicates the master number-slave           : 3pcc extended mode: indicates the slave number-slave_cfg       : 3pcc extended mode: indicates the file where the master and slave addressesare stored*** Performance and watchdog options:-timer_resol     : Set the timer resolution.

No more new calls are placed and all ongoing callsare finished before SIPp exits.Example: kill -SIGUSR1 732USR2: Triggers a dump of all statistics screens in<scenario_name>_<pid>_screens.log file. Especially useful in background mode to know what the current status is.Example: kill -SIGUSR2 732Exit codes:Upon exit (on fatal error or when the number of asked calls (-moption) is reached, SIPp exits with one of the following exitcode:0: All calls were successful1: At least one call failed97: Exit on internal command. Calls may have been processed99: Normal exit without calls processed253: RTP validation failure-1: Fatal error-2: Fatal error binding a socket

About server

如何启动服务端，开启一个UAS

./sipp -sf example-server.xml -i host -p port  --max_socket 100000 -l 500000

服务端脚本一般如何设计：

一般根据实际生产情况，存在client-bye, server-bye, server-rejected, client-cancel, server-cancel等多种情况
以下展示最为常见的主叫挂断：client-bye，即被叫服务侧需要能够接受客服端的bye指令，并回复200ACK

<?xml version="1.0" encoding="UTF-8" ?>
<scenario name="Basic UAS scenario"><recv request="INVITE"><action><ereg regexp="sip:(.*)>.*" search_in="hdr" header="Contact" assign_to="trash"/>
</action></recv><!-- since SIPp complains about not used variable reference the trach var --><Reference variables="trash"/><send retrans="500"><![CDATA[SIP/2.0 200 OK[last_Via:][last_From:][last_To:];tag=[pid]SIPpTag01[call_number][last_Call-ID:][last_CSeq:]Contact: <sip:[local_ip]:[local_port];transport=[transport]>Content-Type: application/sdpContent-Length: [len]v=0o=user1 53655765 2353687637 IN IP[local_ip_type] [local_ip]s=-c=IN IP[media_ip_type] [media_ip]t=0 0m=audio [media_port] RTP/AVP 0a=rtpmap:0 PCMU/8000]]></send><recv request="ACK"></recv><recv request="BYE"></recv><send><![CDATA[SIP/2.0 200 OK[last_Via:][last_From:][last_To:][last_Call-ID:][last_CSeq:]Contact: <sip:[local_ip]:[local_port];transport=[transport]>Content-Length: 0]]></send></scenario>

1. 收到 INVITE 回200
2. 收到 ACK
3. 收到 BYE 回200

About client

如何启动服务端，开启一个UAC

指定送往的代理地址，指定并发量，指定总量级，指定被叫(含前缀)

./sipp proxyhost:port -sf example-client.xml  -r batchsize  -d 10000 -s caller -m totalcount

还有其他很多个指标页面

对于客户端的脚本，通常要与服务端对应，也可以模拟一些异常情况，随机回复到异常的情况，比如呼叫后取消、呼叫后保持、呼叫后挂起一段时间等

<?xml version="1.0" encoding="UTF-8" ?>
<scenario name="Basic UAC scenario"><send><![CDATA[  INVITE sip:[service]@[remote_ip]:[remote_port] SIP/2.0Via: SIP/2.0/[transport] [local_ip]:[local_port]From: sipp <sip:sipp@[local_ip]:[local_port]>;tag=[call_number]To: sut <sip:[service]@[remote_ip]:[remote_port]>Call-ID: [call_id]Cseq: 1 INVITEContact: <sip:sipp@[local_ip]:[local_port]>Content-Type: application/sdpContent-Length: [len]v=0o=user1 53655765 2353687637 IN IP[local_ip_type] [local_ip]s=-t=0 0c=IN IP[media_ip_type] [media_ip]m=audio [media_port] RTP/AVP 0a=rtpmap:0 PCMU/8000]]></send><recv response="100" optional="true"></recv><recv response="180" optional="true"></recv><recv response="200"></recv><send><![CDATA[ACK sip:[service]@[remote_ip]:[remote_port] SIP/2.0Via: SIP/2.0/[transport] [local_ip]:[local_port]From: sipp <sip:sipp@[local_ip]:[local_port]>;tag=[call_number]To: sut <sip:[service]@[remote_ip]:[remote_port]>[peer_tag_param]Call-ID: [call_id]Cseq: 1 ACKContact: <sip:sipp@[local_ip]:[local_port]>Content-Length: 0]]></send><send retrans="500"><![CDATA[BYE sip:[service]@[remote_ip]:[remote_port] SIP/2.0Via: SIP/2.0/[transport] [local_ip]:[local_port]From: sipp <sip:sipp@[local_ip]:[local_port]>;tag=[call_number]To: sut <sip:[service]@[remote_ip]:[remote_port]>[peer_tag_param]Call-ID: [call_id]Cseq: 2 BYEContact: <sip:sipp@[local_ip]:[local_port]>Content-Length: 0]]></send><recv response="200"></recv></scenario>

1. 发送 INVITE
2. 等待100、180的可选指令 ，200 的必要指令
3. 收到200后，发送 ACK
4. 而后发出 BYE指令，最终等待200返回

About testcase

根据以上描述的内容，需要构建好双端的测试脚本，生产情况需要覆盖尽可能多的业务场景，压测情况可以采用正常来回的脚本

successful call bye from client

./sipp -sf uas.xml -i host -p port  --max_socket 100000 -l 500000
./sipp proxyhost:port -sf uac.xml  -r 5  -d 10000 -s 20240715 -m 5

正常先开启服务端，再启动客户端，根据代理的能力，服务端可以多端口多开
