چکیده

In this paper a heuristic algorithm for finding an optical path in elastic optical path networks is proposed. The proposed algorithm for connection requests finds a spectrum required from an aggregated spectrum of the path belonging to a set of shortest paths measured by the number of links. It has been shown that the proposed algorithm rejects definitely fewer connection requests than the well-known algorithms solving the same problem. Streszczenie. W pracy zaproponowano heurystyczny algorytm wyboru ścieżek w elastycznych sieciach optycznych. Zaproponowany algorytm zajmuje dla napływającego żądania wymagane pasmo w zagregowanym widmie ścieżki, należącej do zbioru najkrótszych ścieżek mierzonych liczbą łączy. W pracy wykazano, że algorytm ten odrzuca mniejszą liczbę żądań niż znane algorytmy minimalizujące rzeczywistą długość ścieżki. (Kierowanie i przypisanie widma dla połączeń o stałej szybkości transmisji w elastycznych sieciach optycznych).

A Novel Protection Guaranteed, Quality of Transmission Aware Routing and Wavelength Assignment Algorithm for All-optical Networks

Transparent All Optical Networks carry huge traffic and any link failure can cause the loss of gigabits of data; hence protection and its guarantee becomes necessary at the time of failure. Many protection schemes were presented in the literature, but none of them speaks about protection guarantee. Also, in all optical networks, due to absence of  regeneration capabilities, the physical layer i...

Spectrum Defragmentation in Elastic Optical Networks

Elastic optical networks (EONs) provide fine bandwidth allocation granularity and enable scalable network management. In this paper, we review the strategies to alleviate spectrum fragmentation from both the preemptive and proactive perspectives. As for preemptive defragmentation, we investigate the characteristics of bandwidth fragmentation in EONs, and then discuss a fragmentation-aware routi...
