1.1 overview
The following chart provides advanced overview of this architecture (when "-" means using XMPP communication, "=" means using other protocols)
C1 ---- S1 --- S2 --- C3
|
C2 ---- - g1 === fn1 === fc1
Symbol representation:
C1, C2, C3 = XMPP client
S1, S2 = XMPP server
G1 = gateway converted between XMPP and using an external message network (non-XMPP) protocol
Fn1 = external message network
FC1 = client of external message network
