摘要： In an ATM switching network, ATM (asynchronous transfer mode) self-routing switches are interconnected by facilities carrying STM-N (synchronous transport modules level N) signals. At each inlet of an ATM self-routing switch, an STM overhead is removed from each frame of an incoming STM-N signal to create a vacant interval and the frame is converted according to ATM cell format into a series of data ATM cells, and an idle ATM cell is derived from the vacant interval. A supervisory bit sequence is inserted to the payload field of the idle ATM cell to produce a supervisory ATM cell, and the data and supervisory ATM cells are sent into the ATM switch. At each outlet of the switch, the bit sequence of the supervisory ATM cell is checked to evaluate the quality of the ATM switch and a series of data ATM cells is then converted into an STM-N signal according to STM-N frame format.

摘要： A route switching system in a communications network constituted of a transmitter and a receiver connected by a plurality of routes for switching a first route along which communication is being held by transmission of cells to a second route causing no blocking. The route switching system comprises a first switch provided in the transmitter for switching input cells from one route to another and outputting the cells, a first storage portion provided in the transmitter for storing the input cells, a second switch provided in the receiver for switching input cells from one route to another and outputting the cells, and a second storage portion provided in the receiver for storing the input cells. At the time when the route is switched over, the first switch is changed over so that the cells are transmitted through the first storage portion and, on the receiver side, the second switch is changed over so that the cells transmitted over the second route are stored into the second storage portion. The transmitter includes a switching signal generating portion for outputting, at the time of route switching, a switching timing signal to the receiver side through the first switch, and the receiver includes a switching signal detecting portion for detecting the switching timing signal from the switching signal generating portion. When cells are stored into the first and second storage portions while the route is switched over, the cells are stored first into the second storage portion on the receiver side.

摘要： A method for structuring a communications network based on an asynchronous transfer mode in which communications are held with the use of cells transferred between a node on the upstream side and a node on the downstream side. The method for structuring the network includes a step for preparing a plurality of VPI conversion tables for converting VPIs of the cell input under normal communicating conditions and that of the cell input in the event of a failure and outputting the cell with the VPI converted. The prepared VPI conversion tables are reorganized for each node and the reorganized VPI conversion tables are distributed to all nodes. Then, an alternate route monitoring and switching virtual path is set up in each alternate route and a monitoring cell is periodically transmitted along the alternate route. When a failure occurs, the VPI conversion table is switched over according to the pattern of the failure and the input VPI is converted in accordance with the switched VPI conversion table, and thereby, an alternate virtual path is set up in the relevant alternate route.

摘要： A method includes the steps of a failure which occurs in a node or link, and b) identifying at most N (N is an integer equal to or greater than 2) nodes contained in each path affected by the occurrence of the failure. Each path is connected to a sender node which detects the failure, information is transferred to the sender node via the N nodes, and the sender node serves as a start point of each alternate path which is to be established. The method also includes the step of c) broadcasting a restoration message to links which outgo from the sender node, where the restoration message has an identifier of the sender node and identifiers of the N nodes specified for each path affected by the occurrence of the failure. The identifiers of the N nodes specified for each path being candidate nodes of an end point of each alternate path. The method als includes a step of d) determining whether or not a node being considered is one of the candidate nodes, where the node which is one of the candidate nodes is a destination node. Further, the method includes the steps of e) passing the restoration message through a repeater node which is a node other than the candidate nodes, and f) determining a route via which the restoration message has been transferred to the destination node to be an alternate path connected between the sender node and the destination node.
