Kami mencadangkan skim perlindungan berkelajuan tinggi untuk penghantaran trafik kelas keutamaan berbilang dalam rangkaian cincin WDM. Skim ini mencapai perlindungan berkelajuan tinggi dengan menggantung penghantaran trafik keutamaan rendah dengan cepat apabila kegagalan dikesan. Setiap nod menggantung penghantaran trafik keutamaan rendah yang dihantar melalui laluan sandaran yang sepadan dengan laluan utama terjejas selepas menerima pemberitahuan kegagalan dan menyemak jadual yang merangkumi laluan utama yang melalui nod, laluan sandaran yang sepadan dengan laluan utama, dan trafik keutamaan rendah yang dihantar oleh nod. Jika nod mengesan kegagalan, ia menghantar pemberitahuan kegagalan tunggal untuk setiap gelang ke nod sumber laluan utama, dan nod pada laluan secara berurutan menggantung trafik keutamaan rendah. Simulasi menunjukkan bahawa skim yang dicadangkan mengurangkan masa pemulihan kegagalan sehingga 60% berbanding dengan skim konvensional.

Abstract: We propose a high-speed protection scheme for multiple-priority-class traffic transmission in WDM ring networks. This scheme achieves high-speed protection by quickly suspending transmission of low-priority traffic when a failure is detected. Each node suspends transmission of the low-priority traffic being sent over the backup path corresponding to the impaired primary path after receiving a failure notification and checking a table that includes the primary paths passing through the node, the backup paths corresponding to the primary paths, and low-priority traffic transmitted by the node. If a node detects a failure, it sends a single failure notification for each ring to the source node of the primary path, and the nodes on the route sequentially suspend low-priority traffic. Simulation shows that the proposed scheme reduces the failure-recovery time by up to 60% compared with the conventional scheme.

AB - We propose a high-speed protection scheme for multiple-priority-class traffic transmission in WDM ring networks. This scheme achieves high-speed protection by quickly suspending transmission of low-priority traffic when a failure is detected. Each node suspends transmission of the low-priority traffic being sent over the backup path corresponding to the impaired primary path after receiving a failure notification and checking a table that includes the primary paths passing through the node, the backup paths corresponding to the primary paths, and low-priority traffic transmitted by the node. If a node detects a failure, it sends a single failure notification for each ring to the source node of the primary path, and the nodes on the route sequentially suspend low-priority traffic.
