Generating Tokens after Received Packets¶

The PacketBasedTokenGenerator is a passive packet sink, and generates a configurable number of tokens into a token-based server when receiving a packet.

Packets are generated by an active packet source (ActivePacketSource), and pushed into the token generator (PacketBasedTokenGenerator). The generator generates tokens into a token-based server (TokenBasedServer). When the server has tokens, it pops packets from the connected packet provider (PassivePacketSource), and pushes them into a packet consumer (PassivePacketSink).
