However, existing routing algorithms rarely consider the inherent characteristic of optical circuit switching in ONoC, namely, the exclusive occupation of link bandwidth during communication. Failure to properly address this feature may exacerbate network congestion and degrade overall performance, particularly in long-distance communications that follow shortest-path routing. To address this issue, this paper proposes a novel congestion-aware adaptive routing algorithm based on reinforcement learning (RLCAR), aiming to enhance network throughput and reduce communication latency. Unlike traditional approaches that rely solely on shortest-path selection, the proposed scheme routes path-setup packets dynamically by jointly considering queuing delays and the length of the prospective path. Furthermore, we employ the proposed algorithm to the VCmesh network and conduct simulations under different traffic patterns and network scales using OPNET. Simulation results demonstrate that, in the 6 × 6 network under uniform traffic, transpose traffic, hotspot-point traffic, and hotspot-area traffic pattern , the proposed routing approach achieves reducing and network average end-to-end delay by 14.9%, 17.9%, 14.1%, and 13.5%, respectively, while improving the maximum throughput by 12.4%, 0.8%, 13.7% and 12.8%, respectively, and increasing the optical path insertion loss by 4.64%, compared with length-optimized-routing-protocol (LORP) routing. As the network scales up, the proposed method exhibits even greater advantages in latency and throughput optimization, at the cost of a slight increase in optical insertion loss.</div></div>","PeriodicalId":19663,"journal":{"name":"Optical Fiber Technology","volume":"97 ","pages":"Article 104523"},"PeriodicalIF":2.7,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145797935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Key performance indicators, including background block error rate (BBER), errored seconds (ES), errored seconds rate (ESR), severely errored seconds (SES), and severely errored seconds rate (SESR), were analyzed to quantify the effects of mechanical disturbances on radio link stability. Experimental results show that high-amplitude accelerations cause temporary degradation in channel quality, leading the system to downgrade its modulation scheme from high levels, such as 4096 quadrature amplitude modulation (QAM), to lower levels, like 4 QAM. These degradations were reversible, as modulation levels returned to higher states once channel conditions improved. Additionally, performance degradations were found to be associated with physical factors such as structural contact issues at the radio link pole, external interferences, or wind-induced oscillations. Unlike conventional methods, the proposed system enables remote and real-time detection of environmental mechanical anomalies.
