An efficient and fast fault restoration mechanism based on m:n architecture with bandwidth constraints is proposed while three evaluating parameters are selected and formulated. The comparison of restoration performance, which is based on different protection range such as local restoration, partial path restoration and path restoration, is given. Also the proposed analytical algorithm can be applied to evaluate the restoration performance of MPLS networks when based on 1+1, 1:1 or 1:n architecture.
