Fibre Channel over IP ( FCIP ) is a transport protocol which Fibre Channel packets in TCP wraps around them through standard TCP / IP networks to transport. FCIP is described as an open standard in RFC3821 and is supported by various manufacturers. FCIP means can be used, for example, the existing Ethernet infrastructure for transmission of the Fibre Channel data.

Fibre Channel is used primarily for use in storage area networks and is characterized by link -based flow control and loss of freedom. These two characteristics ( flow control and loss of freedom ) to ensure usually about hardware implementations. In the tunneling of Fibre Channel over IP networks, these characteristics must also preserved. It is not possible to pack FC directly in IP, because IP does not guarantee any flow control or freedom from loss. Therefore, FC can be tunneled via TCP.

FCIP is not very common. In recent years, increasingly Fibre Channel over Ethernet ( FCoE ), where again no simple Ethernet Nets Witche be used, but those that can map ( flow control and loss of freedom ).
