The invention relates to a package starting control device determining a moment and a sequence of starting a package corresponding to an individual wavelength to be wavelength-division-multiplexed in a wavelength division multiplex transmission device. An object of the invention is to provide a package starting control device capable of effectively increasing or decreasing the number of wavelengths at low cost without changing a basic structure drastically. The package starting control device is constructed such that operational states of optical modules that generate optical signals wavelength-division-multiplexed into wavelength division multiplexed optical signals are monitored, the optical signal output by packages that generate the optical signals wavelength-division-multiplexed into the wavelength division multiplexed optical signals during a period when any of the operational states is not in a steady state is restricted and the restriction of the optical signal output by one package of the packages each time the period elapses is released.

Package starting control device

A method for controlling associations in time of executing an application layer in OSI (Open Systems Interconnection) between one communication equipment and the faced communication equipment is disclosed. An association confirmation request from one communication equipment is sent to the faced communication equipment. A reason of the rejection is identified when the faced communication equipment rejects the association confirmation request, and then, the association confirmation request is retransmitted according to the reason of rejection. The times of retransmission is counted to finish retransmitting the association confirmation request in the case where the count value exceeds a predetermined value.
