摘要： Dynamic restoration involves routing and bandwidth assignment of an unplanned restoration path in a wavelength switched optical network (20), having regeneration nodes (60), nodes each having a ROADM (62) having drop paths and add paths. An electrical switch (68) provides configurable regeneration capacity by coupling selected drop paths to selected add paths. Some of the configurable regeneration capacity is kept for unplanned restoration paths. A PCE determines (120) routing and bandwidth assignments for an unplanned restoration path for the traffic flow to avoid a fault, and sends (130) configuration messages to the nodes to set up the unplanned restoration path dynamically and to configure the electrical switch to provide regeneration on the path. Keeping some reconfigurable regeneration capacity enables much longer unplanned paths to be found to avoid faults, and enables wavelength conversion if needed. Thus the reliability of finding at least one path avoiding the fault can be increased.

摘要： Recovery from failure of a working path for communications traffic in a connection- oriented network, where the working path has a preplanned recovery path, involves initiating recovery by requesting computation of a new recovery path (120, 210) for the communications traffic to avoid the failure. If the recovery is not successful within a time limit, (130, 230) recovery is carried out using the preplanned recovery path (140, 240). Determining if the recovery is not successful and initiating the recovery using the preplanned recovery path can be controlled by an ingress node (30) of the working path. By trying to compute a new recovery path first, network resources can be used more efficiently, as the new recovery path is likely to reuse most of the working path, since it is computed knowing the location of the fault.
摘要翻译：在面向连接的网络（其中工作路径具有预先计划的恢复路径）中的用于通信业务的工作路径的故障恢复涉及通过请求计算用于通信业务的新的恢复路径（120,210）来启动恢复，以避免失败。如果在时间限制内恢复不成功，则使用预先计划的恢复路径（140,240）执行恢复（130,230）。确定恢复是否成功并且使用预先计划的恢复路径启动恢复可以由工作路径的入口节点（30）来控制。通过尝试首先计算新的恢复路径，可以更有效地使用网络资源，因为新的恢复路径可能会重用大部分工作路径，因为它是计算知道故障位置的。

摘要： The invention relates to a method in a border node of an optical network and in an external optical channel originating apparatus and to a border node of an optical network and a router. The invention is particularly applicable to optical path validation in an optical network for an externally originating optical channel. The invention may be used during an optical path fault recovery operation. In the method in a border node of an optical network optical channel traffic parameter associated with an optical channel are received from an optical channel originator external to the optical network. The received optical channel traffic parameters are used to determine the suitability of at least one optical path within the optical network for an externally originating optical channel. If a suitable optical path is determined an optical channel availability message indicating the availability at the border node of an optical path within the optical network for the optical channel is sent to the optical channel originator. In the method in an optical channel originator external to an optical network the optical channel traffic parameters associated with an optical channel originating at the optical channel originator are sent to a border node of the optical network. An optical channel availability message indicating the availability at the optical network border node of an optical path within the optical network for the optical channel with which the optical channel traffic parameters are associated is received from the border node. An available optical channel status of the optical channel is determined from the received optical channel availability message for the optical channel.

摘要： A connection-oriented optical network (2) comprises nodes (10) and optical links (5) between nodes. Each node (10) has a power control unit (60) for controlling an optical amplifier (43) at the node. A node, in response to a requirement to set up a new connection in the network, signals to a power control unit (60) at each of a plurality of downstream nodes along a path of the new connection to cause the power control unit at the node to adjust the optical amplifier at the node to support a new optical channel to carry the new connection. The node (10) can signal to tear down an existing connection in a similar way. A downstream node determines a number of optical channels for which the optical amplifier can be adjusted concurrently, based on an existing number of active optical channels.

摘要： A CPRI link involves using a protocol stack (230) having a CPRI layer (232) and an emulation layer (234) to emulate a point to point link, to enable the CPRI link to operate over a packet switched network. The emulation layer can be a pseudowire emulation which encapsulates multiple CPRI frames in a packet with overhead. A multiplexing layer such as IP or MPLS can be used, sending the packet over an Ethernet network. The usual need for a point to point infrastructure for the CPRI link can be avoided and the CPRI link can be implemented over more complex but usually cheaper packet networks, thus reducing costs or enabling more widespread application over existing packet networks. This applies whether the packet network is dedicated to the CPRI link, or is shared with other packets. It can be useful for distributed radio base stations.

摘要： A supervisory channel is provided on an optical path (31) between nodes of an optical communication network. The nodes are arranged to use a set of wavelengths allocated for carrying traffic channels. An optical signal (16) which carries a supervisory channel is generated at a supervisory channel transmitter (15) and added (12) to the optical path (31) downstream of an optical amplifier (11). The optical signal (16) has a wavelength which is one of the set of wavelengths allocated for carrying traffic. The method is performed at a time when the wavelength is not being used to carry traffic. An impairment parameter of the received optical signal is measured at a supervisory channel receiver (15). The receiver is a coherent receiver and the impairment parameter is chromatic dispersion or polarisation mode dispersion.

摘要： A method for measuring asymmetry in propagation delay of first and second links which connect a first node to a second node of a communication network. The method comprises measuring (101) a round trip delay of the first link. The round trip delay can be measured by transmitting (102) a test signal from the first node to the second node over the first link and receiving a reply to the test signal from the second node over the first link. The method further comprises measuring (105) a round trip delay of the second link. The round trip delay can be measured by transmitting (106) a test signal to the second node over the second link and receiving a reply to the test signal from the second node over the second link. A difference in the propagation delay of the first link with respect to the second link is determined (109) using the measured round trip delays of the first link and the second link.

摘要： Path computation through nodes of a communications network to meet a desired security level against unauthorised physical access to the path, involves receiving a request (200) for selection of a new path, and using a record (210) of connectivity of the nodes and links with indications of a security level against unauthorised physical access to the path. This can enable the path routing to be made so as to assure a given level of security of the underlying hardware of nodes and links, in networks where not all parts can provide such security. Nodes can report their current security levels to update the record. A previously selected path can be validated by comparing indicated current security levels of the nodes of the path with the desired security level.
