络测速软件IPERF

實驗目的：
使用網路測量軟體iperf，並藉由改變其參數來觀察無線網路的產出量或封包遺失率等變化。

實驗環境配置：
使用iperf 時必須有iperf server 端與iperf client 端，因此，我們以一部架設無線基地台的桌上型電腦做為server 端(作業系統為windows)，再以一部簡易型電腦(Eee PC)(作業系統為Linux)做為client 端。

實驗步驟：
server 端：
首先，server 端必須先啟動iperf server 服務。程序為開啟Dos 視窗，並參考下列參數說明啟動server 服務『iperf –s –參數』。注意要做的題目是UDP 或TCP，不同的傳輸模式在開啟server 時所下的參數亦不同。

Client 端：
開啟Eee PC 中的「無線網路」選項，並選擇與SSID 為「WN_Lab」的基地台聯結，接著開啟一終端機程式(Ctrl+Alt+t)，並輸入『iperf –c X.X.X.X(server IP) –參數』與server 聯結，並依題目改變所下的參數。若須更改基地台設定(如：Channel No.)，請在server 端可開啟網頁並在網址欄輸入192.168.1.1 進入無線基地台設定頁面，並由其中改變設定，進入設定頁面預設帳密皆為”admin”，請不要更改。更改完後client 端可能要重新聯結。

參數說明：
Usage: iperf [-s|-c host] [options]
iperf [-h|–help] [-v|–version]

Client/Server:
-f, –format [kmKM] format to report: Kbits, Mbits, KBytes, MBytes
-i, –interval # seconds between periodic bandwidth reports
-l, –len #[KM] length of buffer to read or write (default 8 KB)
-m, –print_mss print TCP maximum segment size (MTU – TCP/IP header)
-o, –output output the report or error message to this specified file
-p, –port # server port to listen on/connect to
-u, –udp use UDP rather than TCP
-w, –window #[KM] TCP window size (socket buffer size)
-B, –bind bind to , an interface or multicast address
-C, –compatibility for use with older versions does not sent extra msgs
-M, –mss # set TCP maximum segment size (MTU – 40 bytes)
-N, –nodelay set TCP no delay, disabling Nagle’s Algorithm
-V, –IPv6Version Set the domain to IPv6

Server specific:
-s, –server run in server mode
-D, –daemon run the server as a daemon
-R, –remove remove service in win32

Client specific:
-b, –bandwidth #[KM] for UDP, bandwidth to send at in bits/sec
(default 1 Mbit/sec, implies -u)
-c, –client run in client mode, connecting to
-d, –dualtest Do a bidirectional test simultaneously
-n, –num #[KM] number of bytes to transmit (instead of -t)
-r, –tradeoff Do a bidirectional test individually
-t, –time # time in seconds to transmit for (default 10 secs)
-F, –fileinput input the data to be transmitted from a file
-I, –stdin input the data to be transmitted from stdin
-L, –listenport # port to recieve bidirectional tests back on
-P, –parallel # number of parallel client threads to run
-T, –ttl # time-to-live, for multicast (default 1)

Miscellaneous:
-h, –help print this message and quit
-v, –version print version information and quit
