gosh! thanks for the great replies.
i have a new pattern which seems significantly faster.
s4 is the high volume socket
plist = zpoller_new(s1, s2, s3, s4)
for(;;){
read up to 50 msgs NOBLOCK from s4
sock = zpoller_wait(plist)
if(sock == s1 or s2 or s3) process sock

Hi Devs,
In socket_base.cpp, there is this code:
// If required, send the identity of the local socket to
the peer.
if (peer.options.recv_identity) {
msg_t id;
rc = id.init_size (options.identity_size);
errno_assert (rc
Thanks very much for your clear answer.
On my side, I have digged a little. The ROUTER initializes randomly a id
variable, then increments it each time a new peer connects. This ensures
that for 2^32 connections, the IDs are different. So, to answer my own
question, I1a != I1b.

Hi Laurent,
The RFC is authoritative. If you read the section "Detecting ZMTP 1.0

It might be that your libjzmq.so and jzmq.jar are out of sync.
Like Pieter mentioned, use JeroMQ unless you specifically need JZMQ.

Yeah, that is what is worrying me as well (no commits).
Thanks, Matt !

I haven’t had any problems. I recently switched from clrzmq to NetMQ and I’m
talking to ruby processes using the rbczmq gem (which I chose because it was
faster and more ruby-like in its implementation than the ruby-ffi zmq gem).
I can’t speak for the maintainers of clrzmq. There have been no co
Is it compatible with zeromq? I mean i can interop from C# side using netmq
to ruby-ffi with native zeromq and vice versa?
Officially it means native zeromq binding to CLR is dead?

i’ve just switched to using poller and wanted to verify my “pattern”.
i have 4 incoming sockets. 3 are (very) low volume but need low latency
the other socket is high volume where (almost) any latency will do.
my pattern is to initialize the poller with the high volume socket last,

Artem,
There is no way to know that a node on the network went down without the lack
of receiving acknowledgements that the message was received — either with TCP
ACKs or a messaging pattern in 0MQ such as REQ/REP.
If the the server is not up yet, and you have not established a session, then
hi Justin. Thanks for heads up.
Ok. Clear. Especially about steady stream.
But, again, let me make it very clear.
I imagine following situations and desired outcomes:
- Server is not up yet, and client tries to send a message. Desired
outcome: big red alarm -- "fail" w/o waiting for reply.
- Serv
There is a new feature on 4.x called ZMQ_IMMEDIATE that will, depending on the
socket type, prevent the message from being queued if the pipe (tcp socket) is
not yet established.
With this option enabled, the send will block until a connection is
established, or a send(DONTWAIT) will return fal
Artem,
This is a problem that every network developer faces. Did my message make it to
its destination? If I send a message, is it likely to make it to the recipient?
Fortunately, there are patterns to use to increase reliability, but even then
there is no way to be 100% sure that when a mes
Took a look at the high level C++ binding. It already does all that my
single file template does.
I use some modules of czmq under C++ and felt that it didn't make sense to
be using zframe, zmsg, zstr under C++.

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:

for me.
