Ring Protection : ウィキペディア英語版 | Ring Protection
In Telecommunication networks, ring topology is often used. These ring networks can be self healing which is necessary to ensure up time in the telecommunication industry. There are two widely used protection architectures. == 1+1 Ring Protection ==
In one plus one (1+1) architecture, a single protection path is used to protect the signal. In this case the bridge at the head of the path is permanent. It is at the tail end where the switching occurs. In this architecture traffic is sent over two parallel routes, and the destination or the receiving end selects the better of these two signals. In case of any failure, the destination switches onto the alternative path/route. This architecture is simple for implementation and results fast restoration. Its major drawback is the wastage of bandwidth, since no traffic travels through the redundant path.
