NDDS_Transport_Plugin * | NDDS_Transport_UDPv4_new (const struct NDDS_Transport_UDPv4_Property_t *property_in) |
Create an instance of a UDPv4 Transport Plugin. | |
Built-in transport plug-in using UDP/IPv4.
This transport plugin uses UDPv4 sockets to send and receive messages. It supports both unicast and multicast communications in a single instance of the plugin. By default, this plugin will use all interfaces that it finds enabled and "UP" at instantiation time to send and receive messages.
The user can configure an instance of this plugin to only use unicast or only use multicast, see UDPv4Transport_Property_t::unicast_enabled and UDPv4Transport_Property_t::multicast_enabled.
In addition, the user can configure an instance of this plugin to selectively use the network interfaces of a node (and restrict a plugin from sending multicast messages on specific interfaces) by specifying the "white" and "black" lists in the base property's fields (Transport_Property_t::allow_interfaces_list, Transport_Property_t::deny_interfaces_list, Transport_Property_t::allow_multicast_interfaces_list, Transport_Property_t::deny_multicast_interfaces_list).
RTI Connext can implicitly create this plugin and register with the dds::domain::DomainParticipant if this transport is specified in rti::core::policy::TransportBuiltin.
To specify the properties of the builtin UDPv4 transport that is implicitly registered, you can either:
Note that all properties should be set before the transport is implicitly created and registered by RTI Connext. Any properties set after the builtin transport is registered will be ignored. See Built-in Transport Plugins for details on when a builtin transport is registered.
The following table lists the predefined property names that can be set in rti::core::policy::Property of a dds::domain::DomainParticipant to configure the builtin UDPv4 transport plugin.

self | NOT USED. May be NULL. |

NDDS_Transport_Plugin* NDDS_Transport_UDPv4_new | ( | const struct NDDS_Transport_UDPv4_Property_t * | property_in | ) |
Create an instance of a UDPv4 Transport Plugin.
An application may create and register multiple instances of this Transport Plugin with RTI Connext. This may be to partition the network interfaces across multiple RTI Connext domains. However, note that the underlying transport, the operating system's IP layer, is still a "singleton". For example, if a unicast transport has already bound to a port, and another unicast transport tries to bind to the same port, the second attempt will fail.
The transport plugin honors the interface/multicast "white" and "black" lists specified in the NDDS_Transport_UDP_Property_t::parent:
The format of a string in these lists is assumed to be in standard IPv4 dot notation, possibly containing wildcards. For example:
property_in | <<in>> Desired behavior of this transport. May be NULL for default property. |
