Anritsu MT8821C - TCP;UDP Throughput

216
TCP/UDP Throughput 5.2.7.
5.2.7.1. MT8820C
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, open the iperf application.)
2. Run the following commands to put the client PC into the wait status.
TCP: [iperf -s -i 2 -w 2M -p 50000]
UDP: [iperf -s -u -i 2 -w 2M -p 50000]
(If the DUT is smartphone, open the iperf application.)
TCP: [-s -i 2 -w 2M -p 50000]
UDP: [-s -u -i 2 -w 2M -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: [iperf -c 192.168.20.11 -w 2M -t 100000 -i 1 -p 50000]
UDP: [iperf -c 192.168.20.11 -b 150M -w 2M -t 100000 -i 1 -p 50000]
5. The IP data throughput is displayed at the iperf application on the client server.
[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: [iperf -c 192.168.20.12 -w 2M -t 100000 -i 1 -p 50000]
UDP: [iperf -c 192.168.20.12 -b 150M -w 2M -t 100000 -i 1 -p 50000]
5. The IP data throughput is displayed by the iperf application on the client server.

3. Open the Command Prompt window on Application Server 1 and execute [cd c:¥] to change to the directory
containing Iperf.exe
4. Run the following commands to send data from Application Server 1.
TCP: [iperf -c 192.168.20.11 -B 192.168.20.10 -w 2M -t 100000 -i 1 -p 50000]
UDP: [iperf -c 192.168.20.11 -B 192.168.20.10 -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.
