NAME

zmq_tipc - 0MQ unicast transport using TIPC

SYNOPSIS

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

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.

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 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);
