sipp学习(二)

利用编译成功的sipp，先模拟两个命令，在两个终端上面分别运行：

./sipp -sn uas //服务端
./sipp -sn uac 127.0.0.1　　//客户端

两个终端会建立连接，发送INVITE 、100、180、200 OK、ACK、PAUSE、BYE、200 OK命令。
可以通过 +、-、*、/来改变发送频率，q 退出。

• 在服务端显示的第一个列表项：

  监听端口 Port	总的时间长度 Total-time	总的发送次数 Total-calls	协议类型Transport
  5060	1217.46 s	4175	UDP

• 在客户端显示的第一个列表项：

  发送频率 Call-rate(length)	端口 Port	总的时间长度 Total-time	发送次数Total-calls	远程端的ip Remote-host
  10.0(0 ms)/1.000s	5061	417.52 s	4175	127.0.0.1:5060(UDP)

sipp内部定义了默认以下几种场景：

"uac",
"uas",
"regexp",
"3pcc-C-A",
"3pcc-C-B",
"3pcc-A",
"3pcc-B",
"branchc",
"branchs",
"uac_pcap",
"ooc_default",
"ooc_dummy",

每个场景其实对应一个xml，sipp程序内部已经帮我们添加了该xml。要想研究xml的使用规则，我们从这些系统默认的xml开始学起。

想查看每个场景所对应的xml，可以用命令:
./sipp -sd uac
./sipp -sd uas
将会打印出默认的场景对应的xml。
