ABSTRACT:
A path switching apparatus which performs high-speed switching for quick recovery of an entire network is provide. The apparatus in advance stores information on possibility that an error affects other paths and, upon detecting an error, investigates a possibility of the error affecting other paths with the use of the stored information, predicts further possible path error before it is actually detected, and based on predicted information, detection of error, switching judgment and/or switching are performed as necessary, thus recovering the entire network quickly.
