In wavelength division multiplexing transmission, nonlinear effects such as cross phase modulation between the pulses of channels with different wavelengths due to overtaking causes pulse distortion and timing jitter. In particular, deterioration of

In WDM single-hop networks, a data channel reservation protocol to transmit variable-sized messages efficiently has been proposed. Networks have some data channels and a control channel to assign a data channel in the protocol. A timeslot of the cont
