Resource Reservation Techniques in WDM Optical Networks: A Comprehensive Survey

Abstract

In WDM optical networks, wavelength is the critical resource for efficient communication of traffic. Hence, suitable protocols are required to allocate and use the wavelengths efficiently. We have studied the protocols already developed and reported in literature, for such networks, and considering the historical development, we have outlined some generalized classification for them. We have also provided comparison of their performances. Finally, on the basis of the previous works, we have discussed some future scopes, which may be explored for further improvement in performance of the protocols.
