  1. CS492 Lab Summary

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

  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. 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. 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 802.11g 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 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. 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. 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)
