The level that encompasses the mapping of upper layer protocols (ULP) such as IP and SCSI to lower protocol layers (FC-0 through FC-3).
Examples of FC-4 standards are the mapping of SCSI commands to Fibre Channel (FCP), mapping of Single-Byte Command Code Sets (FC-SB), and the mapping of NVMe to Fibre Channel (FC-NVMe-3).
