摘要： A transmission unit and a failure recovery method with failure recover functions, which use limited network resources efficiently. A label table manager manages a label table which associates incoming labels related to incoming transmission data with outgoing labels related to outgoing transmission data. Based on the label table, a transmission controller performs label-switching of transmission data. A path set-up unit establishes a loop-shaped protection path that includes a part or whole of transmission links of an existing working path and would allow transmission data to flow in the opposite direction to that of the working path. When a failure occurs, a failure recovery controller changes the association between the incoming and outgoing labels stored in the label table and switches the failed part of the working path to the loop-shaped protection path, thereby restoring the label-switched network.

摘要： PROBLEM TO BE SOLVED: To select a link to be used by a communication path in each hop and adaptation in a management domain or a layer boundary appropriately and automatically, according to a service class and a maintenance requirement, without complicating a control sequence in an MPLS/GMPLS network.

Secondly, each node includes a means for deciding maintenance requirements of the communication path and adaptation, based on the server identifier and/or the service attribute. Thirdly, by comparing the maintenance conditions of network resources with the above maintenance requirements, a link and a node passing on the communication path are determined. The determined link, node and adaptation are set as operation parameters of a switch and/or an interface. COPYRIGHT: (C)2009,JPO&INPIT

摘要： A method for protection switching includes receiving an optical signal from a transponder coupled to a client and optically splitting the signal to a first output and a second output. The first output is coupled by a first optical add-drop multiplexer to a first optical fiber, and the second output is coupled by a second add-drop multiplexer to a second fiber. The method further includes selecting one of the output signals for the working channel, and communicating the selected output signal to an optical network. During communication of the selected output signal to the optical network, the method includes monitoring for a failure condition in the optical network and, if the failure condition is detected, selecting the other output signal as the working channel and communicating the new selected output signal.

摘要： A node device is constructed such that the number of relayings can be reduced where communication is performed between terminal equipments connected to this node device. A signal from the terminal equipment is stored in a buffer of the node device. A part of output channels of a connection unit for selecting the output channel of the buffer is guided to a separation unit of this node device. The separation unit separates a signal, which is to be output to the terminal equipment connected to this separation unit, and sends the separated signal to this terminal equipment.
