Anritsu MT8820C - TCP;UDP Throughput

229
TCP/UDP Throughput 5.3.6.
This chapter explains TCP/UDP throughput measurement using the Iperf software for downlink throughput tests.
Uplink throughput measurement is supported by switching the application server and client PCs.
1. Open two Command Prompt windows on the Client PC and execute [cd c:¥] to change to the directory
containing Iperf.exe. (If the DUT is a smartphone type, open the iperf application)
2. Run the following command to put the client PC into the wait status.
TCP: [iperf -s -w 2M -i 1 -p 50000]
UDP: [iperf -s -u -w 2M -i 1 -p 50000]
(If the DUT is a smartphone, open the iperf application)
TCP: [-s -w 2M -i 1 -p 50000]
UDP: [-s -u -w 2M -i 1 -p 50000]
3. Open the Command Prompt window on Application Server 1/2 and execute [cd c:¥] to change to the
directory containing Iperf.exe.
[Case1:Linked EPS Bearer Identity = 5, Client IP Address = 192.168.20.11]
4. Run the following commands to send data from Application Server 1 and 2.
TCP from Application Server1: [iperf -c 192.168.20.11 -B 192.168.20.10 -w 2M -t 100000 -i 1 -p 50000]
TCP from Application Server2: [iperf -c 192.168.20.11 -B 192.168.20.100 -w 2M -t 100000 -i 1 -p 50000]
UDP from Application Server1: [iperf -c 192.168.20.11 -B 192.168.20.10 -b 300M -w 2M -t 100000 -i 1 -p
50000]
UDP from Application Server2: [iperf -c 192.168.20.11 -B 192.168.20.100 -b 300M -w 2M -t 100000 -i 1 -p
50000]
[Case2:Linked EPS Bearer Identity = 6, Client IPAddress2 = 192.168.20.12]
4. Run the following commands to send data from Application Server 1 and 2.
TCP from Application Server1: [iperf -c 192.168.20.12 -B 192.168.20.10 -w 2M -t 100000 -i 1 -p 50000]
TCP from Application Server2: [iperf -c 192.168.20.12 -B 192.168.20.100 -w 2M -t 100000 -i 1 -p 50000]
UDP from Application Server1: [iperf -c 192.168.20.12 -B 192.168.20.10 -b 300M -w 2M -t 100000 -i 1 -p
50000]
UDP from Application Server2: [iperf -c 192.168.20.12 -B 192.168.20.100 -b 300M -w 2M -t 100000 -i 1 -p
50000]
5. The IP data throughput is displayed by the iperf application on the client server.
Note: Refer to B.3, adjust the buffer size (“-w” option argument) to match the performance of the Application
Server and the data rate.
Change the port number (“-p” option argument) to match the Application Server. The same port number
may be used by other applications on the PC.
