    Greetings thrinath.seelam.  I'd suggest starting with our SAN glossary for reference.  its a bit dated (2008), but does provide a great intro on many of the fibre channel terms. 

    http://www.brocade.com/downloads/documents/glossaries/Brocade_SAN_glossary.pdf

    For the 10-bit addressing, please reference the Admin Guide which can be found at:

    The primary port types are covered in the glossary.  M_port is a mirror port.  Backend ports are basically the internal ports (ie ASIC to ASIC).  10-bit addressing is very much addressed in the 2nd link.  Please see "10-bit addressing mode" in the Admin Guide.  The primary point i was trying to make in my original reply is your questions are actually covered in our existing documentation, but for your BB_credit question can also reference:

    http://www.brocade.com/downloads/documents/html_product_manuals/FOS_AG_710/wwhelp/wwhimpl/js/html/wwhelp.htm#href=xfabs.30.6.html

    You will find helpful topics such as Buffer credit management, Buffer-to-buffer flow control, Optimal buffer credit allocation, Buffer credit allocation based on full-sized frames, Fibre Channel data frames, etc, etc.
