FC-4: ULPs—Application Protocols
The layers FC-0 to FC-3 serve to connect end devices together by means of a Fibre Channel network. However, the type of data that end devices exchange via Fibre Channel connections remains open. This is where the application protocols (Upper Layer Protocols, or ULPs) come into play. A specific Fibre Channel network can serve as a medium for several application protocols—for example, SCSI and IP.
The task of the FC-4 protocol mappings is to map the application protocols onto the underlying Fibre Channel network. This means that the FC-4 protocol mappings support the Application Programming Interface (API) of existing protocols upward in the direction of the operating system and realize these downward in the direction ...
