CoreDX DDS Tips & Tricks

Welcome to this month's edition of CoreDX DDS Tips & Tricks, where our engineers provide quick bits of information to help our customers.

Which port numbers are used by DDS?

CoreDX DDS applications don't need to configure IP addresses or port numbers. However, if your system is securing unused ports, it's important to know which are used by DDS. DDS port numbers are determined by an algorithm specified i the DDS standards, which allows interoperability between different DDS implementations.

This algorithm is based on Domain ID, and generated 4 port numbers: one for multicast discovery data, one for unicast discovery data, one for multicast user data, and one for unicast user data. For example, DDS applications using Domain ID 0 will use the following port numbers:

  • Discovery - multicast: 7400
  • Discovery - unicast: 7410
  • User - multicast: 7401
  • User - unicast: 7411

CoreDX DDS Tips & Tricks are intended to be useful for engineers using CoreDX DDS. If you have any questions, please contact us here.
