    摘要： A method is disclosed of reconfiguring a ring optical network made using a single optical fiber (100). A traffic concentrator (120) and stations (140) are optically connected to the fiber. The concentrator sends a light signal to and receives a light signal from both ends of the fiber using two groups of wavelengths (110, 150) in order to be able to communicate with all the stations. When the network is established, a virtual break (170) is created between two stations. If a real break is detected in the optical fiber, then the virtual break is shifted until it coincides with the real break, thereby enabling traffic to be re-established between the concentrator and the stations. Each station is equipped with a three-state optical switch (400) for changing the direction of the light signals.

    摘要： The present invention relates to a method of monitoring the transmission of optical signals including a step of inserting a monitoring signal (S) more particularly suited to monitoring the quality of service. During the transmission of optical signals each carried by a predefined wavelength defining a transmission channel (Ci), said signals are grouped onto the same fiber in a band (B) of channels. The method then includes a step of simultaneously modulating said signals grouped in the band of channels using the monitoring signal to be transmitted, so that each of the signals constitutes a carrier of the monitoring signal.

    摘要： In order to switch selectively via a packets switching matrix waiting in the input modules (IMi) to address output modules, an arbitration function (CSC) selects by successive cycles, from all the pairs of input and output modules, separate subsets. Each cycle comprises p successive phases (x) associated respectively to p arbitration functions. Processing units (PUi) each execute the p functions, each function acting on three parameters termed “residual required quantity”, “input capacity” and “output capacity”, the values of which are related to a single pair and are set at the start of the cycle. Each phase consists of N successive steps (y) associated respectively to said subsets, each step being executed in parallel by the processing units (PUi) in order to calculate by means of the arbitration functions the “partial” accepted quantity values and to reset the parameters for the next step. Application to telecommunication networks, particularly multiservice.

    摘要： A packet-switched communications network (PSN) includes a multiplicity of nodes (Ni) adapted to switch streams of packets benefiting from circuit emulation services, known as CES packets. The network uses a particular method of resynchronizing the CES streams. According to that method, for a CES stream intended to take an associated path (CE) from an ingress node (N1) passing through a set of nodes including a subset of nodes adapted to resynchronize CES streams selectively, effective resynchronization of said stream by a node selected from said subset is conditioned by a value representative of the cumulative jitter suffered by said stream as far as that node.

    摘要： An optical telecommunications network (1000), of metropolitan area type, having a ring type core (10), and secondary rings (41, 42; 43, 44). In each sending access node (11), transmitters (111) for sending information-carrying optical signals use a wavelength belonging to a group of wavelengths dedicated to the secondary ring (41, 42) to which this sending access node (11) is connected. In each destination access node (21), receivers (212) are capable of receiving all the wavelengths used by sending nodes (11) of the network. Communication nodes (1, 2) comprise all-optical devices (100, 101, 10; 201, 20) for inserting, into the core fiber (10), optical signals sent by a sending access node connected to the communication nodes. Optical couplers (31, 32), for taking from the core fiber (10) a so-called representative signal formed of a fraction of the power of each information-carrying signal, are respectively coupled to the receivers of the destination nodes.
