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.

摘要： Apparatus (10) for an optical communications network has optical paths for optical traffic, and optical ports (20, 40), one of which is an unused output port (20). A security monitoring system (30) has a blocking part (50) coupled removably to the unused output port to occupy it to prevent unauthorised access. An optical detector (60) can detect optical signals passing through the unused output port to the blocking part, and there is alarm circuitry (70) configured to output an alarm signal based on the detecting of the optical signals. This monitoring can help make the node more secure from interference or from eavesdropping. By blocking the port, the monitoring can be independent of the type of signals on the optical paths. The system can be passive or active, and does not require a change in the installed node configuration and so can be added easily to existing infrastructure.

摘要： A path computation client (PCC) (21) can request a path computation element (PCE) (22) to compute a path across a wavelength switched optical network. PCC (21) sends a request which identifies end nodes (10). The end nodes (10) can support a plurality of possible values of a transmission parameter, such as modulation format or Forward Error Correction (FEC) type. The PCE (22) computes a path between the end nodes andsends a reply to the PCC (21). The reply identifies the path between the end nodes and identifies a selected value of the transmission parameter for the computed path. The reply can comprise a spectrum assignment for the path. The reply can be a PCE Communication Protocol (PCEP) Reply message.

摘要： An optical transmitter has a modulator for modulating data onto an optical signal for transmission to the receiver (410), the modulated signal having components at one or more constellations of points of different amplitudes and phases. The modulator (30, 70, 630, 633, 680, 800, 810, 820, 830) is tunable such that distortions of the points of the one or more constellation can be tuned, and a tuning controller (20) is provided for receiving a feedback signal from the receiver indicating a distortion measured at the receiver, and for tuning automatically the modulator to adjust the modulation based on the received feedback signal to pre-compensate for the measured distortion. Such pre-compensation can reduce the amount of distortion in the transmission system and thus enable more transmission capacity, without the need for a complex transmitter.

摘要： Apparatus (10) for an optical communications network has optical paths for optical traffic, and optical ports (20,40), one of which is an unused input port (20). A security monitoring system (30) has a blocking part (50) comprising an interface (51) coupled removably to the unused input port(20)to occupy it to prevent unauthorised access. A light source is optically coupled to the interface(51) such that, when the interface is coupled to the unused input port, light can be transmitted through the interface (51) into the unused input port (20). An optical detector (60) can detect light reflected back from the interface (51), and there is alarm circuitry (70) configured to output an alarm signal based on the detecting of the reflected light. This monitoring can help make the node more secure from interference such as the introduction of a noise signal. The system can be passive or active, and does not require a change in the installed node configuration and so can be added easily to existing infrastructure.
