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

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 –p 9901 –n 1000Mb –i 1 TCP server C:>iperf –s –p 9901 Ex) TCP connection between server and client

4 Lab#1 [1/3] (1) Measurement of the throughput of TCP link using iperf program in g 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 Lab#1 [2/3] (2) Measurement of link bandwidth using the UDP test of iperf program in g 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 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 Lab#2 (1) Starcraft gamming using the IPX protocol in g networks

8 Lab#3 [1/3] (1) Measurement of the throughput of the TCP link or link bandwidth using the two different LAN cards in b networks Measurement environment & scenario b 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 Lab#3 [2/3] (2) Measurement of the throughput of TCP link according to the different channel configuration in b 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 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)
