This section describes the supported protocols and includes the following topics:

Protocol here refers to software in the networking layer in kernel space. 

The IPoIB protocol passes IP traffic over the IB network. Configuring IPoIB requires similar steps to 
configuring IP on an Ethernet network. SDP relies on IPoIB to resolve IP addresses. (See the 

.)

To configure IPoIB, you assign an IP address and subnet mask to each IB port. IPoIB automatically adds 
IB interface names to the IP network configuration. To configure IPoIB, see 

SRP runs SCSI commands across RDMA-capable networks so that IB hosts can communicate with Fibre 
Channel storage devices and IB-attached storage devices. SRP requires an SFS with a Fibre Channel 
gateway to connect the host to Fibre Channel storage. In conjunction with an SFS, SRP disguises 
IB-attached hosts as Fibre Channel-attached hosts. The topology transparency feature lets Fibre Channel 
storage communicate seamlessly with IB-attached hosts (known as SRP hosts). For configuration 
instructions, see 

SDP is an IB-specific upper- layer protocol. It defines a standard wire protocol to support stream sockets 
networking over IB. SDP enables sockets-based applications to take advantage of the enhanced 
performance features provided by IB and achieves lower latency and higher bandwidth than IPoIB 
running sockets-based applications. It provides a high-performance, data transfer protocol for 
stream-socket networking over an IB fabric. You can configure the driver to automatically translate TCP 
to SDP based on a source IP, a destination, or an application name. For configuration instructions, see
