NAME

       fast-discovery-server - centralized broker for DDS service discovery

SYNOPSIS

       fast-discovery-server -i ID [options]

DESCRIPTION

       eProsima  Fast DDS, as a Data Distribution Service (DDS) middleware implementation, offers
       the feature of dynamically discovering communication entities within a  network.  The  DDS
       standard  defines a Simple Discovery Protocol (SDP) to accomplish such a task, sharing the
       participants information using well known multicast addresses and ports. While this method
       has  the  advantage  of  out-of-the-box  participant discovery, it has the disadvantage of
       scalability, since  the  number  of  exchanged  packets  increases  exponentially  as  new
       participants  are added to the system. Furthermore, it requires multicasting capabilities,
       which may not work reliably (such as for the case of WiFi communication [1]), or  may  not
       even  be present at all. Therefore, eProsima Fast DDS implements the Discovery Server (DS)
       protocol, which is a new discovery mechanism based on a centralized communications  model.
       In  this,  a  core  participant,  referred  to  as  a  Server, handles all the information
       exchanged between participants on the network.

       fast-discovery-server accepts the following arguments:

       -i ID
       --server-id ID
              This is a mandatory argument for the unique server identifier.  Specifies the  zero
              based server position in the ROS_DISCOVERY_SERVER variable.

       -l IP
       --ip-address IP
              Server interface on which to listen to the clients. Defaults to any (0.0.0.0).

       -p PORT
       --port PORT
              UDP port on which to listen to the clients. Defaults to 11811

       -b, --backup
              Creates a server with a backup file associated
