“…The WS strategies presented have conflicting optimization objectives (i.e., maximization of regenerator sharing versus maximization of wavelength sharing) that give rise to a trade-off with respect to the resource sharing [34] (e.g., the SW strategy has lower wavelength overbuild than SR but higher regenerator overbuild). In DISTR, this trade-off is reduced and becomes negligible in the considered scenarios.…”

To exploit the sharing benefits, the scarce regenerators are used for both regeneration and wavelength conversion (WC) leading to a sharing of functionalities. Also, the shared path protection mechanism is exploited to ensure survivability against single-link failures and make the sharing of network resources (regenerators and wavelengths) possible. The paper presents a novel distributed scheme (DISTR) for reservation of regenerators and wavelengths in generalized multi-protocol label switching controlled WSONs, in order to ensure the required level of QoT and survivability. Novel objects and selection strategies for the resource reservation protocol with traffic engineering extensions are proposed and evaluated. The DISTR scheme effectively combines regeneration and WC points, leading to a noticeable reduction of the regeneration usage with respect to the existing schemes. Moreover, a significant reduction of the blocking probability is achieved, independently of the wavelength selection strategy used.

“…QoTguaranteed survivability based on SPP was evaluated for the first time in [34]. In the work, regenerators are selected at the destination and can be used also for WC purposes.…”

“…No wavelength conversion is assumed. The work in [7] evaluates the effect of using regenerators for both improving QoT and wavelength conversion, using the destination-designated strategy of the regeneration points [6]. A trade-off between the main performance metrics (blocking of LSP requests and average regeneration utilization) has been reported.…”
