Token bucket and leaky bucket simulation
This script can only be used to simulate the behavior of a token bucket and leaky bucket. The paremeters have to be defined in the correct meassurments. They are available under the --help command.
Example executions:
python buckets.py --bucket-size=5000 --input-rate=10000000 --rate=100000 --packet-size=1000 --time-lapse=142 --exec-speed=0.2 --packet-dates 1 2 3 4 5 6 30 34 36 38 50 60 80 82 84 86 88 100
python buckets.py --leaky --bucket-size=5000 --input-rate=10000000 --rate=100000 --packet-size=1000 --time-lapse=142 --exec-speed=0.2 --packet-dates 1 2 3 4 5 6 30 34 36 38 50 60 80 82 84 86 88 100
Help command extract:

A python script that simulates the token bucket and leaky bucket algorithms
for flow control in computer networks.
optional arguments:
-h, --help show this help message and exit
--leaky set the bucket to leaky
--bucket-size BUCKET_SIZE
set the bucket size (in bytes) (default 5KB)
--input-rate INPUT_RATE
the rate at which packages arrive (in bytes per
second) (default 10MB/s)
--rate RATE the rate at which tokens arrive to the bucket (in
bytes per second) (default 100KB/s)
--packet-size PACKET_SIZE
the size of each incoming packet (in bytes) (default
1KB)
--time-lapse TIME_LAPSE
the time_lapse in which the bucket functions (in
millisecond) (default 100ms)
--exec-speed EXEC_SPEED
the execution speed of the simulation (in seconds)
(default 0.5seconds/millisecond)
--packet-dates PACKET_DATES [PACKET_DATES ...]
Set of packet dates in milliseconds (default [1, 2, 3,
4, 5, 6, 30, 34, 36, 38, 50, 60, 80, 82, 84, 86, 88,
100])
Feel free to correct it, play with it improve it, etc.
