Abstract:
1. A data transmission system including a resource holding main traffic, and a resource holding sub-traffic different from said main traffic, said data transmission system comprising: a self-healing function of, when a failure related to said main traffic has occurred, detouring said main traffic to the resource of said sub-traffic to salvage said main traffic; a means for suppressing said self-healing function for a specific unit defined in the system; a service line transmitting said main traffic, a protection line which is capable of transmitting sub-traffic different from said main traffic, self-healing function control means for, when a failure related to said main traffic has occurred, carrying out a switching process which switches the transmission path of said main traffic to said protection line to detour said main traffic to said protection line; and switching inhibit control means, when a segment sandwiched between adjacent pieces of node equipment is specified arbitrarily, inhibiting the main traffic set in the transmission path including the specified segment of said service line from being detoured to said protection line by said switching process at said self-healing function control means.
