Imagine a full duplex network of brokers 1 created on "multicast1"
group.
They provide "Service1" functionnality, and all expose a transport
Connector
with "multicast1" discovery value.
A new broker (broker A) comes up and needs "Service1".So, it knows
that it
had to contact some brokers on multicast1 group. It creates a
networkConnector with "multicast1" group value. A full Duplex
connection is
created between this server and all servers of the "multicast1" group.
brokerA can send a request and receive an answer from one broker of
the
"multicast1" group.
Imagine that this new broker (A), provides "Service2", and belongs
itself to
a "multicast2" full duplex group and exposes a transport connector
with the
"multicast2" discovery value.
Imagine now, that one broker of the "multicast1" group (broker B)
needs
"Service2", so, knows that it had to contact the "multicast2" group
and
creates a full duplex networkConnector with "multicast2" group value.
My question is : between broker A, and broker B, how many tcp
connections
will be created ? 2, 3, or 4 ?
