Path protection algorithm with trade-off ability for survivable wavelength-division-multiplexing mesh networks.
We present a new path protection algorithm, called resource sharing degree constraints (RSDCs), for survivable wavelength-divisionmultiplexing mesh networks. We define a parameter k to adjust the resource sharing degree (RSD). When we compute the reserved backup wavelengths, if the RSD is larger than the value of k, more wavelengths are assigned until the RSD is not greater than the value of k. With respect to previous work, RSDCs, adds a valuable elasticity in resource assignment and is able to determine the appropriate trade-offs between the resource utilization ratio and the protection ability.
