Hi all,

        I think that for the MPLS-TP, the better protection scheme to be used is fast-reroute - FRR. Comparing to SDH-like ring protection it can works like MS-SPring, where is possible to achieve less than 50ms switching time, and the use of the protection side of the ring to carry extra-traffic. There are already equipment in the market that works with this idea.

Ciao Alessandro,
                           I think you made a good point.

If, as stated in sveral documents, mpls-tp is going to replace sdh we
have to consider that most of the metro and metro core topology are ring
based.

Diego
