With the increase in traffic volume, there is a concern about communication failure due to the increased communication load in mobile networks. Therefore, a mechanism is needed to suppress network congestion so that applications can be used even in situations where there is heavy traffic volume. One countermeasure is to improve the routing protocol in the mobile networks. The existing routing protocol is a single route control using the optimum route, so traffic is concentrated on links and nodes, and the risk of congestion increases. As a solution to this problem, in this study, we propose the method of multiple routes controlled by distributed transfer in accordance with the bandwidth ratio for redundant routes other than the optimal route during packet transfer. As a result, the utilization rate of the entire network can be expected to improve and congestion will be suppressed. We have evaluated the proposed method and OSPFv2 (Open Shortest Path First Version2) and showed the proposed method has superior throughput and packet loss rate. Finally, we demonstrate that the proposed method has no bias in the packet arrival rate.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_1_description_25":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.14988/pa.2020.0000000087","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_15":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"同志社大学ハリス理化学研究所","subitem_publisher_language":"ja"}]},"item_1_publisher_16":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Harris
