About 1+1 T-MPLS path protection structure, which of the following are correct?

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.

Pat O’Burke was a poor Irishman with a large family, and one morning, waking up very ea
rly from cold and hunger, he decided to go shooting in a wood near his cottage(小屋,村舍). The wood belonged to Lord Northwood, a rich gentleman, and Pat had no right to go there, but in it there were swarms of rabbits and flocks of birds that were good to eat, and Pat determined to take the risk.

Then, looking at Pat with suspicion, he said, “But why are you out so early in the morning?” “Well, sir,” said Pat, “I just came out to see if I could get a breakfast for my appetite.” The whole crowd burst into laughter at Pat’s ready wit, and with a smile Lord Northwood walked on, leaving Pat to try his luck with the rabbits.
