B.nIn 1+1 T-MPLS path protection structure, if a unidirectional fault (transmission direction from node A to Z) occurs to working connection, it will be detected at sink node Z of protecting domain and then node Z selector will switch to protection connectio
C.n1+1 T-MPLS path protection is of unidirectional switching type -- that is to say, only the affected end needs to switch to the protection path and selectors at the two ends are relatively independent.
D.nIn 1+1 T-MPLS path protection structure, to avoid single-point fault, working connection and protection connection should run along isolated routes.
