Title:
ネットワークシステム及びその障害回復方法
Document Type and Number:
Japanese Patent JP5697071
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To rapidly restructure a topology when a fault occurs.SOLUTION: A network system includes a preliminarily determined topology. Each node includes a topology information table 11 having information required for topology construction, a topology associated table 13 coordinating a topology ID against the fault and the topology information table 11, a topology modification detection part 14 for detecting the fault when a frame from other node is received, a topology selection part 15 for selecting the topology ID against the fault, and a frame transmission and reception part 18 for transmitting the frame storing the topology ID selected by the topology selection part 15 to an adjacent node. The topology modification detection part 14 of the adjacent node, when receiving the topology ID from the frame transmission and reception part 18, refers to the topology information table corresponding to the topology ID to modify its own setting.
