    摘要： A control apparatus sets, in a node located at the start point of an aggregatable segment of two or more packet forwarding paths including the aggregatable segment, a packet handling operation for each flow, the packet handling operation being for writing a flow identifier for identifying the flow and a path identifier used for packet forwarding through the aggregatable segment in a region of each of packets to be matched against the matching rule and then causing the packet to be output. The packets respectively belong to the individual flows, and each of the packets is to be forwarded through a corresponding one of the two or more packet forwarding paths. Further, the control apparatus sets, in a node located intermediate on the aggregatable segment, a common packet handling operation for causing the packet that matches the path identifier to be forwarded according to the packet forwarding path. Then, the control apparatus sets, in a node located at the end point of the aggregatable segment, a packet handling operation for performing restoration and forwarding based on the flow identifier.

    摘要翻译： 控制装置在位于包括可聚合段的两个或多个分组转发路径的可聚合段的起始点的节点中设置每个流的分组处理操作，分组处理操作用于写入用于识别 流和路径标识符，用于通过可匹配规则匹配的每个分组的区域中的可聚合段进行分组转发，然后导致分组被输出。 这些分组分别属于各个流，每个分组将通过两个或更多个分组转发路径中的相应一个进行转发。 此外，控制装置在位于可聚合部分中间的节点中设置公共分组处理操作，以使根据分组转发路径转发与路径标识符匹配的分组。 然后，控制装置在位于可聚合段的终点的节点中设置基于流标识符执行恢复和转发的分组处理操作。

    摘要： A path setup method that makes it possible to avoid a failure in path setup even if a state when setting up a path is that a communication device existing in the path is incapable of communication, as well as a communication device using the method, are provided. According to a method for setting up a path through autonomous distributed control in a network in which a plurality of communication devices (NE200 to NE206) are connected, a communication device (NE201) determines whether or not it is possible to communicate with a communication device (NE203) neighboring to the communication device and, if a state is that it is impossible to communicate with the neighboring communication device, converts signaling for setting up a path (P1) passing through the neighboring communication device into signaling for setting a provisional path (P2) detouring around the neighboring communication device.
