| Abstract(in English) | Photonic networks (PNW's) need to be robust against failures as very high-speed optical paths (OP's) like 2.5Gbps, 10Gbps, and so forth, are operated therein. In particular, failure recovery scheme against multiple failures is essential to establish highly reliable PNW. This paper intends to open up an opportunity for the reliability enhancement of PNW, particularly, against multiple failures, and proposes a novel multiple-failure recovery scheme where both pre-assigned and dynamic restorations gracefully co-functions. We begin with network dimensioning using the OP accommodation design tool we developed to determine the effectiveness of the proposed recovery scheme in terms of the survivability. We then implemented a couple of policies as to how pre-assigned and dynamic restorations are co-related into the OP accommodation design tool to find out the criterion determining the order of setting up new OP. |
