Hi Savdekar,
Some big differences are:
FCIP uses a tunnel to transfer data between networks. It relies on SCSI.
FCoE was developed to simplify switches and consolidate I/O in comparison with FCIP. It replaces FC links with high speed ethernet links between the devices that support the network.
iFCP is a new standard that broadens the way data can be transferred over the internet. It combines the FCIP and iSCSI protocols.
Let me know if you have further questions. I hope this helps!

As far as I know an FCIP link between 2 switches will cause a fabric merge, where iFCP does not. Both protocols have been around for many years now (I learned about them back in 2005 already). Nevertheless FCIP is the most popular one of the two and I never encountered iFCP so far, where FCIP is the main tcp/ip tunneling solution for FC in most storage routers like the Cisco MDS 9216i/9222i and the MDS95xx series. Furthermore the Brocade FR7500 and the newer DCX series layer 3 switches all use FCIP and not iFCP.
In some routers you will see iSCSI as well, which is also SCSI, but not FC..

This presentation from EMC World, "FC/FCoE: Topologies, Protocols, and Limitatons," may also be helpful!
