摘要： A FIFO buffer in which respective portions are controlled in a distributed manner is provided. In the FIFO buffer, a number of loop circuits having delay elements are provided in which respective loop circuits are connected to one another in cascade manner. Additionally provided are a number of traffic control units for controlling the signal traffic between respective neighboring loop circuits. In the case where no signal is fed back to a traffic control unit from the output side and also a new signal is transmitted thereto from the input side, the traffic control unit transmits the new signal to the loop circuit which is on the output side. In the case where any signal is fed back to a traffic control unit from the output side and also a new signal is transmitted thereto from the input side, the traffic control unit again transmits the fed-back signal to the loop circuit which is on the output side and transmits the new signal to the loop circuit which is on the input side. In the case where any signal is fed back to a traffic control means from the output side and also no signal is transmitted thereto from the input side, the traffic control means transmits again the fed-back signal to the loop circuit which is on the output side.

摘要： The path management controller 1 refers to resource information 131 including reservation statuses of working paths and advance reserved paths that are set in every link, so as to calculate a route for setting a new path and set this path in this calculated route. If the route for setting this new path cannot be obtained (1) because of a shortage of residual bandwidth of a link of interest, the path management controller 1 refers to the resource reservation information 131 of working paths and advance reserved paths and calculates an alternative route for another existing path used in the link of interest, and moves this path to the calculated alternative route. On the other hand, if the route for setting this new path cannot be obtained (2) because there is no continuous bandwidth sufficient for setting this new path in the link of interest, the path management controller 1 refers to the resource reservation information regarding working paths and advance reserved paths in the link of interest in the resource information 131, so as to execute the time slot rearrangement.

摘要： A route switching method for switching a route in a core network that accommodates service networks including user node apparatuses by use of a server storing path information that includes, in every time frame, a route for a working path and a route for a backup path to be switched over from the working path, both of the working path and the backup path established between two boundary node apparatuses each of which is located on a boundary between the service network and the core network. The server calculates, in response to the connection request from the user node apparatus, a route for a working path and a route for a backup path, and requests the boundary node apparatus to establish this working path. The server can send the route for the backup path to the boundary node apparatus before a failure occurs in the core network. The boundary node apparatus establishes the working path in response to the establishment request for establishing the working path from the server, and can perform a quick recovery by switching over the working path to the backup path when a failure occurs in the core network.
