The Fibre Channel standard is structured into FCP Function Levels, where “FCP” is “Fibre Channel Protocol”. There is a hierarchy of function levels, written
| Table 32. FCP Function Levels | |

FCP Level | Description | |
|
| |
This level defines the cable, transceivers, and connector. For example, the ZeusIOPS | ||
| ||
| This level defines the 8B/10B encoding of the basic word in the data stream. This | |
encoding consists of four characters. A word contains data or contains an ordered set | ||
| that serves as control information. | |
This level defines how the words are structured in frames, sequences, exchanges and | ||
packets. | ||
| ||
| This level defines the common services. All communication through a node passes | |
through the common service protocol level, allowing networking features such as | ||
| “stripping” data, and “multicasting” to many nodes. | |
Maps the lower protocols to the ULPs. | ||

ULP | This is the protocol that is transported by the Fibre Channel. For example, the | |
