Hi Nagaraj,
It sounds like you have a good start, and also some tight performance
requirements.
I suggest you ask your company to hire a signal integrity consultant to go
through
this layout with you. I can recommend Teraspeed and Mentor Graphics as two of
many good companies which could help you.
best regards,

Hi,
generally, the layers should be symmetrical. The details of the layout
depend on the
details of the board.
