Detailed Description

Transport configuration for the ddsr:// RTI Connext DDS backend.

DdsrConf configures the RTI Connext DDS transport, a commercial-grade DDS implementation widely used in safety-critical and real-time embedded systems. It presents the same VLink API as DdsConf (Fast-DDS) but delegates to RTI Connext internally.

Supported Node Types

ddsr:// supports all six node types: kPublisher, kSubscriber, kServer, kClient, kSetter, and kGetter.

URL Format

ddsr://<topic>[?domain=<N>&depth=<N>&qos=<name>]
ddsr://<topic>[?domain=<N>&part=<v>&topic=<v>&pub=<v>&sub=<v>&writer=<v>&reader=<v>]

Component	Description
topic	RTI DDS topic name; formed from host + "/" + path
domain	DDS Domain ID (?domain=, default from VLINK_DDS_DOMAIN env var)
depth	History depth (?depth=, default 0)
qos	Named QoS profile registered via register_qos() (?qos=)
qos_ext	Extended QoS map: part, topic, pub, sub, writer, reader

Note

This header is compiled only when VLINK_SUPPORT_DDSR is defined.

qos and qos_ext are mutually exclusive.

Response topics for RPC are automatically registered with a "___resp" suffix.
