伝送システム
Document Type and Number:
Japanese Patent JP4297636
Kind Code:
B2
Abstract:
There is disclosed a transmitting system which is capable of recovering a fault efficiently, thereby improving transmission quality. When a fault has occurred, a fault message-sending section notifies a fault message including information of a detected location of occurrence of the fault to other devices. A relay/transfer section carries out label switching operation on a packet having a label added thereto and relay/transfer of the packet. The integer calculation section performs a function operation based on flow information of an input packet to calculate one integer corresponding to one input packet. A path-setting section classifies the calculated integer into one of sections divided by boundary values and sets the section as a path for transferring the input packet. Further, the path-setting section adjusts the boundary values, when a fault message is received, or depending on the state of communication. An ingress edge transfer device adds a label to a packet for transferring the packet via the set path.
