DDSIRTP2 — Define default multicast Reader behavior

Source:
Real-Time Innovations, Inc. (Ken Brophy, ken@rti.com)
Summary:
Currently, the specification does not state whether a multicast DataReader must also have a unicast locator or not.
Resolution:
A unicast locator should be supplied for multicast DataReaders so that repair sessions can be sent over unicast. If one is not provided directly, then the Participant's locator can be assumed.

Revised Text:
Revise following entry in Table 8.77 - RTPS SPDPdiscoveredParticipantData attributes:

attribute type meaning
defaultUnicastLocatorList Locator_t[1..*] Default list of unicast locators (transport, address, port combinations) that can be used to send messages to the user-defined Endpoints contained in the Participant.These are the unicast locators that will be used in case the Endpoint does not specify its own set of Locators, so at least one Locator must be present.
