A.nIn 1+1 T-MPLS path protection structure, each working connection has a specific protection connection; working connection and protection connection are bridged at source end of protecting domain. 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. 此题为多项选择题。
