RPR protection with MPLS

Hi All,

I am new to RPR world and probably have not great
undrstanding of it yet.
I was thinking how the network will work when there is
mpls protection working over RPR network. Wouldn't
this double protection delay the traffic and probably
affect the throughput and speed. Is there any document
available which talks about this and what are the
thoughts of RPR gurus about it.

Regards,
Nitin
