2. Implement Router: 11Mbps & 54Mbps
Distance: close-in & 2 meters & 10 meters
TCP only & UDP only & TCP-UDP & UDP-TCP

3. Implement Wireshark: Capture packets/Analyse
VSFTPD: FTP server running on iPhone
gFTP: FTP client running on Linux
UDP Tool: iPhone app/generate UDP
ircv: receive UDP ptk on linux

4. Implement-TCP stream VSFTPD/ gFTP File name Size iTunesSetup.exe 98mb
testfile.rmvb
190.57mb
VSFTPD/ gFTP

5. Implement-UDP packet UDP Tool/ircv.c
ircv: irregular packets(not ‘loss’)
Irregular = lost or bursty arrival

6. Implement-wireshark
wireshark
Capture packets & plot IO graphs

7. Implement-workplace
Linux (ubuntu 11.04)

8. TCP

9. UDP 11Mbps-close,Irregular=0,rate=7packets/s
11Mbps,10M,Irregular!=0,rate=7packets/s

10. TCP-UDP 11MBps,2M 538kb/s 560kb/s 515kb/s UDP 54MBps,CLOSE 889kb/s

11. UDP-TCP
11Mbps,2M
Irreguler=84
54Mbps,CLOSE
Irreguler=0
