Custom routing table format
[
[X, Y, Z, [A, B, C], ...],
[U, V, W, ...]
...
]
Each row in table corresponds to one router. Each value in that row represents port or id of the router (or array of those) in which packet must be sent on routing stage.
4. Routing table format

TRAFFIC_TABLE_BASED - traffic distribution based on table from file
6. Configuration of hotspots
traffic_hotspots: [[N, S, R], ...]
N - node index
S - send probability multiplier
R - receive probability multiplier
7. Traffic table file path
