adding rsockets support into JDK

[Lu, Yingqi]

Hi Alan and Paul,

Thank you for your quick responses. I will add the Java.net support for rsockets and submit the webrev for review. That way, it might be easier for you to provide feedback ☺

I think rsockets today does not support SSL.

Thanks,
Lucy

The proposed API changes are:

Hi Lucy,

This sounds like a good project

Agreed, and i think an important in cloud-like infrastructure environments.

Lucy, do you know if RDMA supports SSL or something equivalent?



but it will need discussion on how to integrate into the APIs. It might better to start out with factory methods on a JDK-specific class in the jdk.net<http://jdk.net/> example. Alternatively, we could look at slotting it in as a new protocol family implementation along the lines of the DatagramChannel.open(ProtocolFamily) method.


Peeling the open methods and consolidating into a separate specific RDMA class or classes is i think better than spreading around the existing nio classes.

It’s hard to provide more concrete guidance without a webrev, looking forward to that.

Paul.
