/cib

both in generator and in queue

Calculating average number of packets in queue and average waiting time from saved packet times files

Add table of packets

data_reader should print reports in JSON to screen

/cib

We create all packets from all sources with time and boolean if they go to the 2nd server. When packets arrive in 1st server we sort them and add handling time. We create a new stream of all not dropped packets and save their sending time. We create all packets from new sources that go to the 2nd server. We sort all packets from all streams by time and add handling time to all.

I've got results:

{"avg_queue_length_Q1": 147.51875248706725, "avg_queue_waiting_time_Q1": 145.32611467328152, "avg_delay_Q1": 146.3261146732814, "avg_load_Q1": 1.017560884567374, "avg_queue_length_Q2": 0.0, "avg_queue_waiting_time_Q2": 0.0, "avg_delay_Q2": 1.0, "avg_load_Q2": 0.20167202655218355}

for params:

python3 main.py -l 2 -t 10000.0 -g 1 -q 0.5 -n 5 -d 4

Right now, when there's no packets in the second queue, there's an error:

Traceback (most recent call last):

It should be handled so that it doesn't crash
