# zmq\_tipc(7)

0MQ unicast transport using TIPC

## 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);
```
