| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In our previous works, for Optical CDM over WDM networks. we proposed a hierachical logical topology construction method which can use all links without loop structure in distributed controlled network. However, since conventional logical topology construction methods do not consider network failure, when a link failure occurs the network must reset all logical topology information and the established lightpath and reconstruct logical topology. In this paper, we propose a method to detect a link failure and to restore hierarchical logical topology autonomously to search an alternative link and change its conficuration after a link failure in a distributed controlled network. Our proposed method saves the order of hierarchical layers and established lightpaths that do not pass through the failed devices. On the other hand, our proposed method has possibility to construct less efficient logical topology than reconstructed logical topology. Simulation results showed that the restored logical topology rejects fewer lightpaths and has nearly equal performance to the reconstructed logical topology. | |
