The RC connection is established with the DGID of the router (it's the equivalent of a MAC address and its ok), the ServiceID + private data in the case of SDP or iSER (or NFS-R assuming the IBTA proposal will pass) also contains info on the REAL destination IP that can be used by the proxy. By the way there is a section on that in the IETF iSER draft talking about iSER to iSCSI routing, but it's a general solution just as applicable to someone doing HTTP proxy to SDP, or NFS/TCP to NFS/RDMA, or SDP to SDP, etc'. to route _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
