Abstract (in Japanese) (See Japanese page) 
(in English) In multi-domain optical networks involving multiple collaborating operators, confidentiality constraints may limit the sharing of intra-domain resource availability, which in turn degrades path computation efficiency. In this study, we investigate a path-based Thompson Sampling (P-TS) approach that sequentially learns the order in which to attempt candidate paths derived from abstract topologies, using only the success or failure of optical path establishment as observable feedback.
Simulation results show that, with 100,000 connection requests, P-TS achieves a lower blocking probability than the representative heuristic KSP-FF for offered loads between 100 and 160 Erlang, with a maximum blocking probability reduction of 10.62%. We also confirm that, under the same request volume and load conditions, P-TS requires fewer path setup attempts on average than KSP-FF.
These results indicate that, even when operator domains do not expose resource availability information to the orchestrator and only limited feedback is observable, sequential path-based learning can reduce both blocking probability and the average number of setup attempts, provided that a sufficient number of samples are available.
