[openib-general] [RFC] IB address translation using ARP

[Sean Hefty]

>I think the usage model is the following: you have some magic device
>that has an IB port on one side and "something else" on the other
>side.  Think of something like a gateway that talks SDP on the IB side
>and TCP/IP on the other side.

>You configure your IPoIB routing so that this magic device is the next

>Now someone tries to make an SDP connection to an IP address on the
>other side of the magic device.  Routing tables + ARP give it the GID
>of the IB port of this magic device.  It connects to the magic device
>and run SDP to talk to the magic device, and the magic device
>magically splices this into a TCP connection to the real destination.

Thanks for the clarification.
