FCIP Protocol The FCIP protocol encapsulates Fibre Channel frames (Fibre Channel or SCSI protocol) into IP packets and fabric domains to IP addresses. The initial goal of iFCP was to replace both FC-SW and SAN with Fibre Channel (FC) over IP network, or simply an IP network. It also discusses FCIP, including its topology and function of merging physically independent storage area network fabrics. These headers interrupt the network stream and reduce the ability of SDR to match large, contiguous data patterns. In FCIP, FC frames are encapsulated onto the IP payload and transported over an IP network. Fibre Channel FCIP - a tunnel protocol based on the TCP/IP which is designed for connection of geographically far FC SANs without affecting FC and IP protocols. This specification covers the TCP/IP requirements for transporting FC Frames; the Fibre Channel documents described in section 2. The FC protocol does allow for out-of-order delivery between FC exchanges however the delivery to the SCSI stack will always be in order. Fibre Channel Over TCP/IP (FCIP) describes mechanisms that allow the interconnection of islands of Fibre Channel storage area networks over IP-based networks to form a unified storage area network in a single Fibre Channel fabric.
