Abstract: Provided are a path control method, a wireless communication system, a path control device, and a non-transitory computer readable medium which are capable of securing efficient traffic accommodation, while maintaining communication quality. The path control method controls a communication path by selecting one path from among a plurality of path candidates with respect to a specific piece of traffic in a network constituted of a radio link provided with an adaptive modulation function. A requested band of the piece of traffic is compared with an allocatable band allocatable to a first path candidate that is included in the plurality of path candidates and that satisfies a degree of stability requested by the piece of traffic by a first modulation method. As a result of the comparison, when the requested band of the piece of traffic is larger than the allocatable band, a penalty cost due to transmission using a band usable by a second modulation method having a lower degree of stability is given to the first path candidate so that the first path candidate is less likely to be selected as compared with the other path candidates for selecting one path from among the plurality of path candidates.

Abstract translation: 提供了能够在保持通信质量的同时确保有效的业务调节的路径控制方法，无线通信系统，路径控制装置和非暂时性计算机可读介质。 路径控制方法通过从由具有自适应调制功能的无线电链路构成的网络中的特定业务量中选择多个路径候选中的一条路径来控制通信路径。 将所述业务的请求频带与可分配给包括在所述多个路径候选中的第一路径候选的可分配频带进行比较，并且通过第一调制方法满足由该业务量请求的稳定程度。 作为比较的结果，当业务的请求频带大于可分配频带时，由于使用具有较低稳定度的第二调制方式可使用的频带的传输造成的惩罚代价被给予第一路径 使得与用于从多个路径候选中选择一个路径的其他路径候选相比，第一路径候选不太可能被选择。

Abstract: A warning apparatus (2000) acquires first detected event information (10) representing, at a first abstraction level, an event set being a set of events having occurred in a target system. The warning apparatus (2000) generates second detected event information (20) from the first detected event information (10). The second detected event information (20) represents, at a second abstraction level, the event set represented by the first detected event information (10). The warning apparatus (2000) determines, from among a plurality of pieces of threat information (30) each representing a threat activity, the threat information (30) having a high degree of relevance to at least either of the first detected event information (10) and the second detected event information (20). The warning apparatus (2000) generates warning information (40) relating to a threat being occurring in the target system, based on the determined threat information (30) and a matching level being an abstraction level associated with the detected event information having a high degree of relevance to the threat information (30).
