Abstract
An optical switching control method and apparatus. The method includes generating an optical switching path corresponding to a destination node of service traffic flowing from an external service network, generating an optical frame corresponding to the generated optical switching path, transmitting, to a control server, a request message for requesting an allocation of a time slot to transmit the generated optical frame, generating an optical signal having a predetermined wavelength to transmit the optical frame in response to an admission message being received as a result of admission with respect to the request message, and transferring the optical frame to the destination node based on the optical switching path using the generated optical signal.
