Abstract: An object is to provide a network device and the like that enable a first network that determines a traffic communication route using the Ethernet ring protocol and a second network that determines a traffic communication route by transmitting/receiving a control frame related to the traffic communication route within the network to be connected in a redundant configuration. When the network device according to the present invention has transitioned to a state in which there is no interface that can communicate with the first network and there is an interface that can communicate with the second network, it transitions to a standby state and further transmits information indicating that communication is impossible to the second network, and when there is an interface that can communicate with the first network and there is no interface that can communicate with the second network, it transitions to the standby state and further transmits communication route change information to the first network.

Abstract: The present invention provides a novel phosphorus-containing phenolic resin. When the phosphorus-containing phenolic resin is used as an epoxy resin curing agent, the cured product thereof has various excellent properties such as excellent moisture resistance, low permittivity, a low dissipation factor, and excellent adhesion in addition to improved flame retardation. Specifically, the phosphorus-containing phenolic resin of the invention is represented by formula (1). The invention also provides a method for manufacturing the novel phosphorus-containing phenolic resin, a phenolic resin composition including the phosphorus-containing phenolic resin, an epoxy resin curing agent including the phenolic resin composition, an epoxy resin composition including the epoxy resin curing agent and an epoxy resin, a cured product obtained by curing the epoxy resin composition, and a copper-clad laminated plate obtained by using the epoxy resin composition as a matrix resin.
