Throttling Android Simulator via Custom Networking Parameters
~ 4 min read. Published 22 Mar 2015This is how you can easily throttle Android networking interface on the emulator. You can go via telnet or netcat.
##TL;DR To set the network interface to have throughput of 6000 bits/s (0.7 KB/s) and 2000 ms latency you would use these commands (for the first emulator that usually defaults to port 5554)
echo "network delay 2000" | nc localhost 5554
echo "network speed 6 6" | nc localhost 5554
For more details and samples read on…
Latency
echo "network delay 8000" | nc localhost 5554
Sample output:
➜ ~ echo "network delay 8000" | nc localhost 5554
Android Console: type 'help' for a list of commands
OK
OK
➜ ~ echo "network status" | nc localhost 5554
Android Console: type 'help' for a list of commands
OK
Current network status:
download speed: 0 bits/s (0.0 KB/s)
upload speed: 0 bits/s (0.0 KB/s)
minimum latency: 8000 ms
maximum latency: 8000 ms
OK
Throughput
echo "network speed 6 6" | nc localhost 5554
Sample output:
➜ ~ echo "network speed 6 6" | nc localhost 5554
Android Console: type 'help' for a list of commands
OK
OK
➜ ~ echo "network status" | nc localhost 5554
Android Console: type 'help' for a list of commands
OK
Current network status:
download speed: 6000 bits/s (0.7 KB/s)
upload speed: 6000 bits/s (0.7 KB/s)
minimum latency: 8000 ms
maximum latency: 8000 ms
OK
