A single instance of a router outage in IP over elastic optical networks affects multiple traffic. This traffic can be recovered using the spare capacities of unaffected flows. When the spare capacities do not suffice for grooming affected traffic, spectrum expansion is possible as long as there is no interference from the neighboring spectrum. However, a new lightpath must be prepared if that is the case. Such a condition leads to increased operator’s operating expense (OPEX). To deal with this issue, we propose an algorithm that combines the spectrum expansion technique with reactive hitless defragmentation, where spectrum defragmentation is carried out to obtain a sufficient number of free frequency slots, allowing the processing of spectrum expansion. Based on the results of simulations, our proposed algorithm, in comparison to the benchmark algorithm, can successfully minimize the number of new lightpaths, which includes reducing the number of lightpath reconfigurations and minimizing additional power consumption to decrease the total cost of additional OPEX.

Pojedyncze wystąpienie awarii routera w protokole IP w elastycznych sieciach optycznych wpływa na ruch wielokierunkowy. Ruch ten można odzyskać, korzystając z wolnych mocy przepływów, na które nie ma on wpływu. Gdy wolne moce przepustowe nie wystarczą do oczyszczenia ruchu, na który ma to wpływ, rozszerzenie widma jest możliwe, o ile nie ma zakłóceń z sąsiedniego widma. Jednak w takim przypadku należy przygotować nową ścieżkę świetlną. Taki stan prowadzi do wzrostu kosztów operacyjnych operatora (OPEX). Aby poradzić sobie z tym problemem, proponujemy algorytm łączący technikę rozszerzania widma z reaktywną defragmentacją bez trafień, w której defragmentacja widma jest przeprowadzana w celu uzyskania wystarczającej liczby wolnych szczelin częstotliwości, umożliwiających przetwarzanie rozszerzenia widma. Na podstawie wyników symulacji zaproponowany przez nas algorytm, w porównaniu z algorytmem wzorcowym, może z powodzeniem zminimalizować liczbę nowych ścieżek świetlnych, co obejmuje zmniejszenie liczby rekonfiguracji ścieżek świetlnych i zminimalizowanie dodatkowego zużycia energii w celu zmniejszenia całkowitego kosztu dodatkowego OPEX.
