pathrate用于测试两点之间的最大带宽；
pathrate和pathload基本安装和用法一样

仍旧分为服务器端和客户端，用法几乎与pathload一样

服务器端启动
[root@server2 pathrate]# ./pathrate_snd


Waiting for receiver to establish control stream =>

在客户端进行测试
[root@server1 pathrate]# ./pathrate_rcv -s 10.10.10.131
        pathrate run from 10.10.10.131 to server1.org on Wed Jul 29 05:11:30 2009
        --> Average round-trip time: 0.4ms

-------------------------------------------------
Final capacity estimate :  712 Mbps  to  725 Mbps   带宽大小
-------------------------------------------------
[root@server1 pathrate]#

服务器端的状态
[root@server2 pathrate]# ./pathrate_snd


Waiting for receiver to establish control stream => OK
Unknown receiver starts measurements on Wed Jul 29 09:45:05 2009
Measurements are in progress. Please wait..
Receiver terminates measurements on Wed Jul 29 09:45:30 2009
