Abstract: A network management apparatus that connects to a terminal by way of a communication apparatus, includes: a legitimate information generation unit configured to generate legitimate identification information that is identification information to identify the terminal on a network that the network management apparatus manages, the legitimate identification information being managed as legitimate information by the network management apparatus; a fake information generation unit configured to generate fake identification information that is different from the legitimate identification information and that cannot be used as it is for communication with another terminal; a management unit configured to manage the legitimate identification information and the fake identification information in association with each other; and a registration unit configured to register the fake identification information to the terminal.

Abstract: A path control system, includes: a forwarding network in which each forwarding node belongs to a group and forwards a packet based on a sub-label corresponding to the group; an edge node that adds a label including a plurality of sub-labels based on information contained in a received packet; and a control apparatus that performs path control of the forwarding network by controlling a combination of sub-labels added by the edge node and by controlling forwarding processing performed based on the sub-labels by the forwarding node(s). When a failure has occurred in a communication path, the control apparatus causes the edge node to change a sub-label corresponding to a failure section of the communication path in which a failure has occurred out of sub-labels added to a packet received after the failure, and causes the forwarding node(s) to forward a packet along a path that does not go through the failure section.

Abstract translation: 路径控制系统包括：转发网络，其中每个转发节点属于一个组，并且基于与该组对应的子标签转发分组; 边缘节点，其基于包含在接收到的分组中的信息添加包括多个子标签的标签; 以及控制装置，其通过控制由边缘节点添加的子标签的组合并且通过控制由转发节点基于子标签执行的转发处理来执行转发网络的路径控制。 当在通信路径中发生故障时，控制装置使边缘节点改变对应于已经发生故障的通信路径的故障部分的子标签，该子标签被添加到在 并导致转发节点沿着不通过故障部分的路径转发数据包。
