Are they any REPs or other documentation describing retry strategies for topics and services?

I don't believe there are generic connection retries implemented at the moment. There was some logic to do so, but it's only experimental.

Thanks, Tully. I think maybe we can roll this into the ROS 2.0 SIG then. Or at least explicitly leave it out :)

The Technical Overview might be a good start. At least for services, retry is dependent if it is a persistent connection or not.

Unfortunately, it doesn't cover retry strategies other than to state that persistent service connections are not retried.

Yes, that is also important information, i.e. the user has to do it. It states (implictly) that non-persistent connections are reconnected on every service call.
