摘要： PROBLEM TO BE SOLVED: To make it possible for a communication system to continue communication services even if both faults of an active route and a standby route of static logical paths occur by a wide area disaster by solving such a problem that at the time of the wide area disaster a network management device cannot determine a disaster-stricken area or perform route switching on the basis of the influence on the communication services by the disaster.SOLUTION: In a communication system to which the invention is applied, a network management device manages faults per area. The network management device determines a fault area on the basis of a fault state of communication devices and connection links between the communication devices and determines whether it is necessary or not to switch a logical path on the basis of a fault state of the logical path. This allows the communication system to continue provision of communication services by use of a route not going through a disaster-stricken area.

摘要： PROBLEM TO BE SOLVED: To solve a problem such that a packet, having a reduced bandwidth due to a ling aggregation (LAG) failure, is discarded in a LAG failure occurrence section.SOLUTION: On the occurrence of the LAG failure due to a physical link failure, a relay node processes reading of a failure occurrence LAG ID, a reduced band and an effective band, triggered by the detection of connectivity abnormality at periodic LACP transmission and reception, to store into an AIS frame and transfer to an edge node. The edge node terminates and analyzes the AIS frame to grasp a failure occurrence LAG ID, a band reduction amount, and an LSP ID passing through the LAG. The edge node then refers to LSP priority to save traffic to a preset standby LSP in order from LSP having the lowest priority to the highest by the amount of the reduced band.

摘要： PROBLEM TO BE SOLVED: To provide a redundancy system that allows communication service to be continued even if multiple faults occur without a single fault point.SOLUTION: A redundant network system is made redundant about devices including a 0-system device and a 1-system device at a certain point in a network, and paths for system switching are set between a neighboring adjacent device 302 and the like and the 0-system device 305 and the 1-system device 308 respectively. A termination device 301 contacting with a user is set redundant paths with the 0-system device and the 1-system device. When the adjacent device has detected a fault of a port on physical port basis, it determines whether the fault port accommodates either of the 0-system path or 1-system path, and determines whether the 0-system/1-system path accommodated on the fault port is active or standby, and transmits a fault notification storing the determined fault status of 0-system/1-system and active/standby to the termination device 301. The termination device 301 includes means for determining whether it performs path switching or system switching from received multiple fault notification messages, and if the system switching is required, it transmits a system switching message to the adjacent device 302 and the like.
