In brief: IPoIB treats an IB fabric as a LAN. As such it has UD semantics. SDP essentially treats the HCA as a TOE and leverages IB's RC semantics to emulate TCP/IP SOCK_STREAM sockets. This protocol implements the interface to communicate to the SilverStorm VEx Ethernet Virtual IO Controllers. The VEx card presents a true Ethernet NIC to the host and essentially treats IB as an IO bus to allow a host CPU to use the VEx card as its NIC.
