Generator.py – Generator

Main Module of the project. The configuration from config/config.ini is parsed. All needed devices (client, server, attacker) are initialized and started as seperate processes.

Functions

start

Generator.start()

Starts the Generator. Reads needed Configurations and initializes Clients, Servers and Attackers. Starts Client, Server and Attackers as seperate processes.

writer

stop

Generator.stop(q, clientCounts, servers, serverQueues)

First Level of stopping all processes. This function is running as a process and waits for all clients to be done (all required messages are sent and no state). In this case, a DONE message is sent to all servers to indicate that no more clients requests will arrive and they can shut down.

Parameters:

• q – Own Queue to listen on incomming DONE messages.
• clientCounts – Number of expected DONE messages.
• servers – List of server instances.
• serverQueues – List of server queues.

stop2

Generator.stop2(q, serverCounts, attackers, attackerQueue)

Second Level of stopping all processes. This function is running as a process and waits for all servers to be done (server got a DONE message previously). In this case, a DONE message is sent to all attackers to indicate that no more packets will arrive and they can shut down.

Parameters:

• q – Own Queue to listen on incomming DONE messages.
• serverCounts – Number of expected DONE messages.
• attackers – List of attacker instances.
• attackerQueue – List of attacker queues.
