Abstract
A protection channel provisioning method includes: reserving a first protection channel corresponding to a first work channel and a second protection channel corresponding to a second work channel; provisioning a shared protection channel by configuring a circuit of node equipment provided on a shared route on which the first protection channel and the second protection channel are redundantly reserved so that a data signal of the first work channel or a data signal of the second work channel is transmitted via the shared route; and configuring a circuit of branch node equipment provided in a branch node at which the shared protection channel is guided to a first node corresponding to the first protection channel and a second node corresponding to the second protection channel so that the data signal transmitted via the shared protection channel is not guided to the first node and the second node.
