DDS RTPS traffic on all interfaces

Hi,


I have inherited a large system which utilizes DDS as a pub/sub mechanism. This is a client/server based system which create domain participants and communicate with each other using various topics. The problem I am facing is that on the server, I see DDS traffic (unicast) going to ALL the interfaces on the client, even those which are not connected and should NOT have been used to create participants or join domains. Is this expected?

 

Wireshark snapshot


As you can see in the snapshot, the traffic is directed to an APIPA.

Hello Farooque,

Can it be that you have NDDS_DISCOVERY_PEERS set to some list of hosts?

Check your environment variables as well as the directory from which you are running the application.

 

Good luck,

Roy.
