[zeromq-dev] What exact networking problems ZMQ does solve?

[artemv zmq]

Okay. Thanks for your thoughts. Again, I read the guide, and I know on
practice what's pub/sub/push/pull/ .. and so on.

But let me ask one more time very concrete and simple question. I want to
develop a client/server appl. Okay. I pick dealer/router pattern. Fine. Now
my requirement is following:
if server is unaccessible (wrong ip address, server is not online, server
was online and then went offline, etc.)  -- in this case I want to get
(_instantly_) some indication that client can't send a message because
server is unaccessible.  It's clear?  Again, I don't want to await for
reply, I want to know right now that I can't send a message.

Realistically, this is very classic  networking issue :)   So, how can ZMQ
help me?  Or is it possible/eligible et al  to implement  transactional
(not batching!)  applications  on ZMQ?
