Untuk menampung jumlah trafik yang semakin meningkat dengan cekap, rangkaian optik elastik (EON) yang boleh menggunakan sumber spektrum optik secara fleksibel telah dikaji. Kami melaksanakan penghalaan berbilang laluan sekiranya kami tidak dapat memperuntukkan spektrum dengan penghalaan laluan tunggal. Walau bagaimanapun, penghalaan berbilang laluan memerlukan lebih banyak jalur pengawal untuk mengelakkan gangguan antara dua laluan optik bersebelahan jika dibandingkan dengan penghalaan satu laluan dalam EON. Algoritma penghalaan berbilang laluan dengan teknologi dandanan trafik telah dicadangkan. Para penyelidik menganggap bahawa tahap modulasi seragam telah diterima pakai, dan oleh itu mereka tidak mempertimbangkan kesan panjang laluan ke atas sumber yang diperlukan. Dalam kertas ini, kami mencadangkan kaedah penghalaan berbilang laluan dengan dandanan trafik mengambil kira panjang laluan. Kaedah cadangan kami mewujudkan berbilang laluan optik dengan mempertimbangkan panjang laluan, penggunaan gentian dan penggunaan dandanan lalu lintas. Simulasi menunjukkan kita boleh mengurangkan kebarangkalian menyekat panggilan sebanyak kira-kira 24.8% dalam NSFNET. Kami juga menunjukkan keberkesanan dandanan lalu lintas dan peningkatan dalam nisbah penggunaan sumber spektrum optik.

Abstract: To accommodate an increasing amount of traffic efficiently, elastic optical networks (EON) that can use optical spectrum resources flexibly have been studied. We implement multi-path routing in case we cannot allocate the spectrum with single-path routing. However, multi-path routing requires more guard bands to avoid interference between two adjacent optical paths when compared with single-path routing in EON. A multi-path routing algorithm with traffic grooming technology has been proposed. The researchers assumed that a uniform modulation level was adopted, and so they did not consider the impact of path length on the resources needed. In this paper, we propose a multi-path routing method with traffic grooming considering path lengths. Our proposed method establishes an optical multi-path considering path length, fiber utilization, and the use of traffic grooming. Simulations show we can decrease the call-blocking probability by approximately 24.8% in NSFNET. We also demonstrate the effectiveness of traffic grooming and the improvement in the utilization ratio of optical spectrum resources.
