Does ZeroMQ ROUTER socket maintain order when using TCP as transport?

I went through some examples using ZeroMQ and found this asynchronous messaging example using a ROUTER socket at the frontend of the server. The documentation states that on incoming requests this socket type will "fair-queue" incoming requests. However, if TCP is used, does that socket maintain order of incoming requests from the same client? For example if client A sends a Message M1 and then M2, the socket will forward M2 after M1 right?

Yes, you can assume that the ordering a client ØMQ sends messages will be received in the same order on the other side. Conceptually, you think of ØMQ Sockets as a message queue.
