NAME¶
zmq_tcp - 0MQ unicast transport using TCPSYNOPSIS¶
TCP is an ubiquitous, reliable, unicast transport. When connecting distributed applications over a network with 0MQ, using the TCP transport will likely be your first choice.ADDRESSING¶
A 0MQ endpoint is a string consisting of a transport:// followed by an address. The transport specifies the underlying protocol to use. The address specifies the transport-specific address to connect to.Assigning a local address to a socket¶
When assigning a local address to a socket using zmq_bind() with the tcp transport, the endpoint shall be interpreted as an interface followed by a colon and the TCP port number to use.•The wild-card *, meaning all available
interfaces.
•The primary IPv4 or IPv6 address
assigned to the interface, in its numeric representation.
•The non-portable interface name as
defined by the operating system.
•A numeric value, usually above 1024 on
POSIX systems.
•The wild-card *, meaning a
system-assigned ephemeral port.
Connecting a socket¶
When connecting a socket to a peer address using zmq_connect() with the tcp transport, the endpoint shall be interpreted as a peer address followed by a colon and the TCP port number to use.•The DNS name of the peer.
•The IPv4 or IPv6 address of the peer,
in its numeric representation.
EXAMPLES¶
Assigning a local address to a socket.// TCP port 5555 on all available interfaces rc = zmq_bind(socket, "tcp:/// :5555"); assert (rc == 0); // TCP port 5555 on the local loop-back interface on all platforms rc = zmq_bind(socket, "tcp://127.0.0.1:5555"); assert (rc == 0); // TCP port 5555 on the first Ethernet network interface on Linux rc = zmq_bind(socket, "tcp://eth0:5555"); assert (rc == 0);
// Connecting using an IP address rc = zmq_connect(socket, "tcp://192.168.1.1:5555"); assert (rc == 0); // Connecting using a DNS name rc = zmq_connect(socket, "tcp://server1:5555"); assert (rc == 0);
