Client to Handle Conversation, Presence and Heartbeats

[Replicator]

Right, so given the protocol, I just described, some messages are
heartbeats, some presence, some raw data => all coming through the same
socket / port, what is the way to model this in Netty?

Is that a single Netty client with 2 different handlers ( upstream,
downstream ) that solve for all these different messages? Is it a single
Netty client with multiple handlers per [UP/DOWN] stream, each responsible
for different things, e.g. heartbeat, presence, consuming messages? Is it
something else?

Thank you.
