摘要： In a method and device performing a change of a line type without saving a service line to a protection line in service at a line level when a unit in service is updated in a transmission device or the like composing a SONET network supporting various types of line connections, when it is analyzed that a control command is requesting a type change of an active line, a change request line in addition to the active line is redundantly managed, and a redundant setting of a line is performed based on line connection setting information of the change request line, and a switchover of the active line to the change request line is performed depending on whether connection destinations of both lines are different or same.

摘要： A communication network system includes a processor, and a plurality of node apparatuses using a protocol to establish paths therebetween, wherein the processor determines each of the node apparatuses to be a packet source or a packet destination, and operates to detect an occurrence of failure in two paths being established between the packet source and the packet destination in the communication network system, and wherein the processor transmits packet data including user data through one of the two paths, and when one of the node apparatuses detects an occurrence of a failure in one of the two paths, the processor changes the path to the other path.
