Note that Fast DDS v2.0.2 is currently only available when compiling ROS 2 Foxy from sources.

Then, configure the Clients (all your nodes) with:Įxport ROS_DISCOVERY_SERVER=127.0.0.1:11811 Open another terminal and source your ROS installation. This command launches a server with ID 0 in 127.0.0.1:11811.Ģ.

Open a new terminal and source your ROS installation.

This brings the easy-to-use ways of ROS 1 master to ROS 2, without the problems that `roscore` imposed in terms of single point of failure. Since Fast DDS v2.0.2, the Discovery Server protocol can be configured by running one executable for bringing up the Server, and setting an environment variable to configure the Clients.

Scarce network resources: The massive reduction of traffic enables the deployments of large systems in network constrained environments.

Heterogeneous networks : No multicast available.

Furthermore, Fast DDS v2.0.2 brings a new CLI that enables launching a Discovery Server with a simple command. No multicast dependency: All Client-Server communication is done using unicast, effectively avoiding discovery related problems on WiFi of heterogeneous networks.įlexibility: Every node can act as a Server or Client distinctively, no daemon process is needed.Įase-of-use: Configuration can be done using either an environment variable of XML files. Persistence : Discovery Servers can be configured to persist the discovery graph, which prevents a new discovery startup in case of a server shutdown. Reliabilit y : All discovery traffic is reliable when using this mechanism. Scala bility : Reduced network traffic and fastests discovery in large deployments.Īvailability : Multiple Discovery servers can be used to avoid a single point of failure. Both SDP and DS 2.0 experiments are performed using Fast DDS v2.0.2 DS 1.0 is performed using Fast DDS v2.0.1. Note: Network related discovery traffic generated by RMF Clinic Demo when using Fast DDS Simple Discovery Protocol (SDP), Discovery Server v1.0 (DS 1.0), and Discovery Server v2 (DS 2.0).

This strategy has reduced the network traffic by up to 93% when compared to the standard SDP, and by up to 83% when compared to the previous implementation of the Discovery Server. eProsima Fast DDS v2.0.2 further reduces the discovery related traffic when using the Discovery Server by only connecting those Clients which have something to say to each other. It does so by replacing the standard peer to peer discovery by one or several Discovery Servers to which the Clients connect.

Designed for large deployments with many nodes, Discovery Server reduces the discovery related network traffic while avoiding typical issues of heterogeneous networks such as package lossover Wifi, or multicast drops in network equipment. Since v1.9.0, eProsima Fast DDS features an alternative to the DDS Simple Discovery Protocol (SDP) mechanism: Discovery Server.
