2. 2 Contents Outline of iperf program Lab#1 (1) Measurement of the throughput of TCP link using iperf program in 802.11g networks (2) Measurement of link bandwidth using the UDP test of iperf program in 802.11g networks Lab#2 (1) Starcraft gamming using the IPX protocol in 802.11g networks Lab#3 (1) Measurement of the throughput of the two different LAN cards in 802.11b networks (2) Measurement of the throughput of TCP link according to the different channel configuration in 802.11b networks (3) Measurement of the throughput of AODV routing protocol in ad-hoc networks

3. 3 Outline of iperf program TCP throughput or link bandwidth (using UDP) measurement program “iperf –help” command shows the usage of the program TCP client C:>iperf –c 143.248.134.26 –p 9901 –n 1000Mb –i 1 TCP server C:>iperf –s –p 9901 Ex) TCP connection between server and client

4. 4 Lab#1 [1/3] (1) Measurement of the throughput of TCP link using iperf program in 802.11g networks Measurement environment & scenario Scenario 1 > TCP throughput measurement between team#1 and TCP server Scenario 2 > TCP throughput measurement between team#1, #2, #3, #4, #5 and the TCP server Scenario 3 > TCP throughput measurement between all teams and the TCP server

5. 5 Lab#1 [2/3] (2) Measurement of link bandwidth using the UDP test of iperf program in 802.11g networks Measurement environment & scenario Scenario 1 > Measurement of link bandwidth using the UDP test between team#1 and UDP server Scenario 2 > Measurement of link bandwidth using the UDP test between team#1, #2, #3, #4, #5 and the UDP server Scenario 3 > Measurement of link bandwidth using the UDP test between all teams and the UDP server

6. 6 Lab#1 [3/3] (3) Measurement of the throughput of TCP link or link bandwidth using UDP test in the connection between team #1 and TCP server Other team’s lab-tops are power-off This scenario examines the effect of control message overhead of access point

7. 7 Lab#2 (1) Starcraft gamming using the IPX protocol in 802.11g networks

8. 8 Lab#3 [1/3] (1) Measurement of the throughput of the TCP link or link bandwidth using the two different LAN cards in 802.11b networks Measurement environment & scenario 802.11b setting of the SNU2 AP Scenario 1 > Measurement of the throughput of the TCP link or link bandwidth using LAN card 1 (Other procedure is the same as Lab#1’s (1) procedure) Scenario 2 > Measurement of the throughput of the TCP link or link bandwidth using LAN card 2 (Other procedure is the same as Lab#1’s (2) procedure)

9. 9 Lab#3 [2/3] (2) Measurement of the throughput of TCP link according to the different channel configuration in 802.11b networks Measurement environment & scenario Scenario 1 > Measurement of the throughput of TCP link with changing the physical channel number(1, 3, 6, 9, 11)

10. 10 Lab#3 [3/3] (3) Measurement of the throughput of AODV routing protocol in ad-hoc networks Configuration of ad hoc network Routing protocol : AODV Power management Scenario 1 > Measurement of the throughput of TCP link using routing path consists of some ad hoc nodes (#7, #6, #2, #1, #4) Team #7 is iperf TCP client and team #4 is iperf TCP server Scenario 2> Starcraft gamming in ad hoc networks (#7, #8, #9, #5, #4)
