Kertas kerja ini membincangkan kaedah penghalaan yang mudah dan pantas dalam rangkaian Pemultipleksan Bahagian Panjang Gelombang (WDM) optik berkapasiti besar. Rangkaian WDM berkapasiti besar adalah perlu untuk menampung beban trafik yang semakin meningkat pada masa hadapan. Dalam rangkaian WDM berkapasiti besar ini, setiap pautan mempunyai banyak gentian dan sejumlah besar data optik boleh dihantar melalui gentian ini secara serentak. Laluan optik dikonfigurasikan untuk menghantar data optik melalui tempahan panjang gelombang termasuk penghalaan dan penetapan panjang gelombang (RWA). Memandangkan kaedah RWA tradisional perlu merawat banyak maklumat tentang panjang gelombang yang tersedia dalam setiap gentian, adalah sukar untuk menyelesaikan masalah RWA tepat pada masanya. Dalam erti kata lain, pemprosesan elektrik menjadi hambatan dalam rangkaian WDM berkapasiti besar. Oleh itu, kaedah RWA yang mudah dan pantas diperlukan untuk rangkaian WDM berkapasiti besar. Dalam kertas ini, kami mencadangkan kaedah RWA yang mudah dan berkesan yang menganggap maklumat yang dikurangkan sebagai Peta Rangkaian. Objektifnya adalah untuk meningkatkan prestasi rangkaian dengan menggunakan pelbagai gentian secara berkesan. Pemprosesan kompleks tidak sesuai untuk penghantaran data kerana operasi pensuisan mesti dilakukan dalam masa yang sangat singkat untuk satu permintaan. Di samping itu, adalah tidak praktikal untuk mengumpul maklumat rangkaian terperinci dengan kerap. Kaedah penetapan panjang gelombang yang dicadangkan memberikan panjang gelombang lebih seragam daripada kaedah tradisional, dan oleh itu, kaedah penghalaan yang dicadangkan boleh memilih laluan tanpa mengambil kira maklumat terperinci tentang setiap keadaan panjang gelombang. Kaedah penghalaan yang dicadangkan hanya memerlukan maklumat tempatan dan maklumat rangkaian yang dikurangkan. Kertas kerja ini menunjukkan bahawa kaedah penghalaan yang dicadangkan boleh mendapatkan penyelesaian yang sesuai untuk rangkaian WDM optikal berkapasiti besar melalui simulasi komputer. Kaedah RWA yang dicadangkan secara drastik meningkatkan kebarangkalian kerugian berbanding kaedah RWA mudah yang lain. Makalah ini juga menerangkan dua jenis suis optik dengan penukaran panjang gelombang boleh tala atau tetap. Penukar panjang gelombang dengan teknologi yang agak rendah menjadi berkesan dengan kaedah RWA yang dicadangkan dalam rangkaian WDM berkapasiti besar. Makalah ini mendedahkan bahawa kaedah penghalaan yang kompleks tidak diperlukan untuk rangkaian WDM optik berkapasiti besar.

Abstract: This paper discusses a simple and speedy routing method in large-capacity optical Wavelength Division Multiplexing (WDM) networks. The large-capacity WDM network is necessary to accommodate increasing traffic load in future. In this large-capacity WDM network, each link has many fibers and a huge amount of optical data can be transmitted through these fibers simultaneously. Optical path is configured for transmitting optical data by wavelength reservation including routing and wavelength assignment (RWA). Since traditional RWA methods have to treat much information about available wavelengths in each fiber, it is difficult to resolve RWA problem on time. In other words, the electrical processing becomes the bottleneck in the large-capacity WDM network. Therefore, a simple and speedy RWA method is necessary for the large-capacity WDM network. In this paper, we propose the simple and effective RWA method which considers reduced information as Network Map. The objective is to improve the network performance by using multiple fibers effectively. The complex processing is not suitable for data transmission because the switching operation must be done in very short time for one request. In addition to this, it is not practical to collect detailed network information frequently. The proposed wavelength assignment method assigns wavelength more uniformly than traditional method, and therefore, the proposed routing method can select routes without considering detailed information about each wavelength state. The proposed routing method needs only local information and reduced network information. This paper shows that the proposed routing method can get suitable solution for large-capacity optical WDM networks through computer simulations. The proposed RWA method drastically improves the loss probability against other simple RWA methods. This paper also describes two types of optical switches with tunable or fixed wavelength conversions. The wavelength converters with relatively low technology becomes effective with the proposed RWA method in the large-capacity WDM network. This paper reveals that complex routing methods are not necessary for large-capacity optical WDM networks.
