5.4. Test Scenario 3 (TS3)

This is the high load scenario. The point of this test is to provide a very high load on the system to see the real-time response of the critical path.

5.4.1. Host

Table 5-5. TS3 Host

Component	Parameters	Instances	Frequency	Payload
httpblast.sh	�	1	2/min	10 KB
latency-server	/dev/ttyS0 infifo -p500000 -i 3000 -l logfile &	1	�	�
echo	"{00000000111111111122222222223333333333444444444455555555556666}" > infifo	1	�	�

5.4.2. Target

Table 5-6. TS3 Target

Component	Parameters	Instances	Frequency	Payload
serialblast	/dev/ttySN	3	2/second	100 bytes
udpblast	host IP	3	100/second	25 bytes
udpblast	host IP	1	100/second	8 bytes
latency-drone	-d [a]	3 sets of 20	�	~10k
latency-client	/dev/ttyS0[b] 10	10 drones	�	�
Notes: a. opens and closes FIFOs after each read/write cycle b. this is an on-board serial port

This test can be easily started by issuing the following commands:

# TS-target.sh <host IP> <serial device>
# dolots.sh <host IP>
