ØMQ Manual - ØMQ/4.1.5

Name

zmq_tipc - ØMQ unicast transport using TIPC

Synopsis

TIPC is a cluster IPC protocol with a location transparent addressing scheme.

Addressing

A ØMQ 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.

For the TIPC transport, the transport is tipc, and the meaning of the address part is defined below.

Assigning a port name to a socket
When assigning a port name to a socket using _zmq_bind()_ with the 'tipc'
transport, the 'endpoint' is defined in the form:
{type, lower, upper}

  • Type is the numerical (u32) ID of your service.
  • Lower and Upper specify a range for your service.

Publishing the same service with overlapping lower\/upper ID's will
cause connection requests to be distributed over these in a round-robin
manner.

Connecting a socket

When assigning a port name to a socket using _zmq_bind()_ with the 'tipc'
transport, the 'endpoint' is defined in the form:
{type, lower, upper}

* Type is the numerical (u32) ID of your service.
* Lower and Upper specify a range for your service.

Publishing the same service with overlapping lower/upper ID's will
cause connection requests to be distributed over these in a round-robin
manner.

Connecting a socket

When connecting a socket to a peer address using zmq_connect() with the tipc transport, the endpoint shall be interpreted as a service ID, followed by a comma and the instance ID.

The instance ID must be within the lower/upper range of a published port name for the endpoint to be valid.

Examples

Assigning a local address to a socket

//  Publish TIPC service ID 5555
rc = zmq_bind(socket, "tipc://{5555,0,0}");
assert (rc == 0);
//  Publish TIPC service ID 5555 with a service range of 0-100
rc = zmq_bind(socket, "tipc://{5555,0,100}"); assert (rc == 0);

Connecting a socket

//  Connect to service 5555 instance id 50
rc = zmq_connect(socket, "tipc://{5555,50}"); assert (rc == 0);
