Abstract (in Japanese) (See Japanese page) 
(in English) With the expansion of network services, the demand for network quality has increased. Fast Reroute (FaRe) is one method to suppress network downtime. By precomputing backup paths, FaRe enables rapid path switching in the event of a failure. While various systems have been proposed to measure and evaluate network quality, such as path latency, it is challenging to evaluate the performance of the backup paths provided by FaRe. In this paper, we construct Route Latency Analyzer (RLA), a system that measures the latency of paths using delay metrics obtained via TWAMP Light and BGP-LS. We evaluate the effectiveness of failure recovery with FaRe, as well as the measurement accuracy of RLA. Experimental results demonstrate that FaRe enables failure recovery within 50 ms. Furthermore, RLA achieved sub-millisecond measurement errors.
