8.4. Metro Fibre Channel Protocol (mFCP)
mFCP is a UDP/IP variant of iFCP. mFCP shares iFCP's architecture for support of FCP over IP, transparent and translational addressing modes, and accommodation of native Fibre Channel initiators and targets. Unlike iFCP, however, mFCP does not have an integral flow control mechanism such as TCP. Instead, mFCP relies on the link-layer flow control of 802.3x to pace traffic over the IP SAN.
There are several immediate benefits to the mFCP implementation, and several cautionary notes are attached. The most obvious benefit is speed. Like Fibre Channel, mFCP simply streams frames from source to destination. There is no prior connection setup as in TCP/IP, and no transmission ramp to test bandwidth availability. ...
