摘要： A method for signalling of data transmission path properties is proposed. The method contains several steps at a first network endpoint device. As a first step, at least one data transmission path is provided via a client-server interface to a client device by the first network endpoint device. The data transmission path is a path through the network connecting the first network endpoint device and a second network endpoint device. As a second step, the first network endpoint device receives via a server-network interface OAM information generated by the second network endpoint device or internal network devices and terminates this received OAM information. As a third step, the first network endpoint device determines at least one data transmission property parameter from such received OAM information which was generated by the second network endpoint device or internal network devices. The fourth step is that of signalling via the client-server interface at least one transmission property message towards the client device in dependence on the at least one determined transmission property parameter.

摘要： An intermediate amplifier device (20) with a signal amplification stage (21) in a transmission network in which signals can be transmitted from a central station (23) to a number of receivers (24) by way of a number of transmission lines, which are connected to one another in a tree structure, with a number of intermediate amplifier devices of the same type is characterized in that the intermediate amplifier device has a detection device (22) for detecting a malfunction (28) in the transmission line (27) connected to the intermediate amplifier device, a switching device (26) for coupling and uncoupling the transmission line (27) to or from the central station, as well as a delay element (25) with a delay time t.sub.i for the delayed reaction to a malfunction detected by the detection device (22) by means of a correspondingly delayed actuation of the switching device. As a result, in the event of a malfunction, only the last intermediate amplifier device before the malfunctioning line section as well as subsequent line parts possibly connected to it are affected, but not network sections that do not receive their signals by way of the affected intermediate amplifier device. Furthermore, the localization of the malfunction is made easier.

摘要： A method and related apparatus are provided for restoring a connection through a provider network (PN). In particular, a connection is established along a path (P1) through the provider network (PN) for the transport of client traffic between two client network nodes (CR1, CR2) of a client network (CD1, CD2). Any restoration service for this connection is deactivated. However, when a failure (F1) is detected along the path (P1) which affects the connection, a path search is performed anyhow to determine a projected restoration path (P2) through the provider network (PN) available to restore said failed connection. In the case that the path search was successful and a projected restoration path (P2) was found, the availability of the projected restoration path (P2) is communicated (MS1, MS2) to the client network (CD1, CD2). The client can now decide whether to accept a temporary service upgrade to restoration service or not. Only after receipt of a confirmation (CM1, CM2) from said client network (CD1, CD2), a path restoration is performed to restore the failed connection over the projected restoration path (P2).

摘要： An optical network device re-routes traffic from a path to a backup path in response to determining that a downstream segment of the primary path is not operational. The optical network device receives traffic on a slot of an optical fiber. For each data unit in the traffic, the optical network device determines, based on receiving the data unit on the slot and based on a flow identifier specified in the data unit, that a given path is associated with the data unit. If a downstream segment of the given path is not operational, the optical network device routes the data unit onto a backup path instead of routing the data unit along the given path. Bandwidth is not reserved for the backup path.

摘要： A method for establishing disjoint data connections between two clients by a network is proposed. The method comprises different steps at different devices. A first client device sends via a client-network interface one or more connection request messages to a network for requesting at least two disjoint data connections to a second client device. The one or more connection request messages contain first indicating data, indicating a first predetermined set of network resources, and second indicating data, indicating a second predetermined set of network resources, which is disjoint to said first set of network resources.

摘要： In a multi-layer transport network, a method and related control plane allow automatic provisioning of a client layer connection (31, 32, 33, 24, 34, 35) over at least one server layer connection (11, 12, 13, 21, 22, 23, 14, 15, 16, 25, 26) by selecting a path through the transport network taking into account free resources of existing server layer connections (14, 15, 16, 25) and additionally taking into account free resources in the transport network, where no server layer connections exist so far. The selection is based on a cost calculation which takes into account a cost value per link and further takes into account an additional cost value for links on which no available server layer connection exist so far. Eventually, the path having the lowest overall cost is selected. Server layer connections (11, 12, 13, 21, 22, 23, 26) on links along said selected path where no server layer connection with free resources exists so far are then established and used to set up the requested client layer (31, 32, 33, 24, 34, 35) connection.

摘要： An intermediate repeater that can make available at least a minimum of information to the end user sites connected with it even in the event of a power failure. The intermediate repeater has a broadband amplifier (AMP) for the amplification of the received broadband signals and for the subsequent forwarding of the amplified broadband signals, as well as a first device (HP1, LP1; S1,LP, C1), which is connected in series to the broadband amplifier (AMP) and is set to separate the received narrow band signals from the received broadband signals according to frequency, and to forward them without amplification by bypassing the broadband amplifier (AMP). Thus, the transmission of the narrow band signals is guaranteed even during a disturbance.

摘要： A broadband communication system (SYS), which is used to distribute television, radio and video signals, is additionally used for transmitting data signals from one subscriber (TN) to another subscriber (TN). The center (ZE) of the broadband communication system (SYS) has a service-on-demand server (SOD) which contains a control facility (CONTROL). The control facility (CONTROL) receives information transmitted by a subscriber (TN) via the return channel (R) to the center, performs a frequency conversion and transmits the information via the downstream channel (V) to all the subscribers (TN) of the broadband communication system (SYS). The information contains a source address, a destination address and the subscriber-specific data to be transmitted. Only subscribers (TN) whose address coincides with the destination address are able to interpret the information through a modem MODEM.
