Communicating across multiple computers with CycloneDDS#

Configuring CycloneDDS#

Within the ~/cyclonedds.xml file, Interfaces section can be set in various ways to communicate across multiple computers within a network.

With this setting, CycloneDDS will automatically determine the most suitable network interface to use.

<Interfaces>
  <NetworkInterface autodetermine="true" priority="default" multicast="default" />
</Interfaces>

With this setting, you can manually set the network interface to use.

<Interfaces>
  <NetworkInterface autodetermine="false" name="enp38s0" priority="default" multicast="default" />
</Interfaces>

Warning

You should replace enp38s0 with the actual network interface name.

Note

ifconfig command can be used to find the network interface name.

To ensure that the nodes on different computers are synchronized, you should synchronize the time between the computers.

You can use the chrony to synchronize the time between computers.
