Delay analyses of wavelength reservation methods for high-speed burst transfer in photonic networks

It is possible to offer a high-speed data transfer capability by employing WDM technology. One promising method is to transfer the data through a fast wavelength reservation. However, the wavelength reservation time, including the propagation delay between source and receiver nodes, becomes large, which may lead to performance degradation. We develop a new approximate analytical method, which incorporates wavelength reservation times. We consider two methods for wavelength reservation; a forward method in which wavelength reservation is performed along the forward path from source to receiver, and a backward method in which it is performed along the backward path. Based on our approximate analysis, we investigate the effects of propagation delays on both methods.
