Abstract: A method for providing a maximum channel capacity per optical channel in an optical wavelength division multiplexing, WDM, transmission system is described. The WDM transmission system includes transceivers using multiple optical channels in a WDM channel grid to transport optical signals modulated with a modulation format with a signal symbol rate, SR, via an optical transmission link, OTL, along an optical path from a transmitting transceiver to a receiving transceiver. A channel capacity of the optical channel is maximized while a calculated channel margin, CM, is maintained above a preset minimal channel margin value.

Abstract: A method and system of correcting a packet delay variation, PDV, of express traffic comprising high-priority express packets interspersed at a transmitter (2) by a preemption mechanism with a best-effort traffic comprising low-priority best-effort packets, wherein the method comprises the steps of: calculating (S1) at the transmitter (2) a preemption delay value, PRDV, which indicates a preemption delay, PD, introduced by the preemption mechanism; writing (S2) the calculated preemption delay value, PRDV, into a delay header field of a header of a high-priority express packet transmitted by said transmitter (2) via a signal line (4) to a receiver (3); extracting (S3) the preemption delay value, PRDV, from the delay header field of the header of the high-priority express packet received by the receiver (3) via the signal line (4) from the transmitter (2); calculating (S4) at the receiver (3) a variation compensation delay, VCD, value by subtracting the extracted preemption delay value, PRDV, from a predetermined worst-case preemption delay value, PRDVworst; and applying (S5) at the receiver an additional delay to the high-priority express packet according to the calculated variation compensation delay, VCD, value to compensate the preemption delay, PD, introduced by the preemption mechanism at the transmitter (2).

Abstract: The invention relates to a method for detecting the absolute temperature or temperature changes and/or the absolute wavelength or wavelength changes of an optical probe signal using an optical detection device including an optical waveguide structure defining an optical input port adapted to receive the optical probe signal and a first and a second optical output port adapted to output a first and a second optical detection signal, respectively. As a response to the optical probe signal, the optical waveguide structure being configured in such a way that a first power transfer function characterizing the transmission of the optical probe signal from the optical input port to the first optical output port differs, with respect to its wavelength and temperature dependency, from a second power transfer function characterizing the transmission of the optical probe signal from the optical input port to the second optical output port. The method includes the steps of transmitting the optical probe signal having a predetermined, but not necessarily constant, wavelength to the optical input port; detecting the first and second optical detection signal at the first and second optical output port by means of a first a and second opto-electrical converter which create a first and second electrical signal corresponding to the optical power of the respective first or second optical detection signal; measuring values of the first and second electrical signal and determining an absolute temperature value or a value of a temperature change of the optical waveguide structure and/or an absolute wavelength value or a value of a wavelength change of the optical probe signal by using the values measured of the first and second electrical signal and a first and a second previously determined wavelength and temperature dependency of both the first and second power transfer function. The invention further relates to an optical detection device for implementing this method.

Abstract: A method for efficient utilization of a transport capacity provided by an optical transport network includes mapping client signals comprising lower order optical data units into optical data tributary units, each requiring a number of tributary slots of an aggregate payload area having a size corresponding to the available aggregated OPU payload areas of Nx independent higher order optical data units to be transported. The method further includes multiplexing the optical data tributary units into the aggregate payload area. The method further includes mapping the tributary slots of the aggregate payload area into tributary slots provided by the OPU payload areas of the Nx independent higher order Optical data units according to a predefined mapping rule. The method further includes multiplexing the Nx independent optical data units containing the payload areas or transmitting them as optical transport units.

Abstract: Dynamically allocating workloads to a fixed number of CPU resources within a compute platform. Determining whether a workload should be in a Dedicated Class of workloads and assigned to a dedicated CPU resource or in a Shared Class of workloads that is handled by a set of at least one shared CPU resource, wherein a shared CPU resource may service more than one workload. The determination may be made based on a comparison of a parameter from two samples of a parameter taken at different times. The determination may be made using metadata associated with the workload. The determination may be made repeatedly so that some workloads may change from being in the Dedicated Class to the Shared Class or from the Shared Class to the Dedicated Class. High availability virtual network functions may be handled economically by deeming the failover workloads to be in the Shared Class.

Abstract: A method and apparatus for increasing the operation lifetime of a beam tube are provided. The method includes converting an electrical current output by the beam tube into an intermediate voltage to provide a voltage signal used for changing an electron multiplier polarization voltage applied to an electron multiplier by a power supply unit controlled by an electron multiplier gain control signal generated by a controller. The controller regulates the electrical current output by the beam tube to keep it below a characteristic current threshold by adjusting the electron multiplier gain control signal until it reaches a predefined maximum value. The voltage signal applied to the controller is regulated by increasing the variable gain of a voltage amplifier to compensate for a drop in electrical current output by the beam tube caused by the aging of the electron multiplier until the applied voltage signal reaches a predefined minimum value.

Abstract: There are provided a method and system for assessing latency of ciphering end point of secure communication channel. The method comprises: generating a test traffic comprising a series of original data packets, wherein, for each original data packet, size of a given packet is uniquely indicative of the packet's place in a sequence of data packets in the series and enables unique correspondence with a size of the given packet upon its encryption; successively transmitting the original packets to the ciphering end point, whilst associating with respective departure time stamps; receiving encrypted packets from the ciphering end point and associating them with respective arrival time stamps; using a size of a given encrypted packet with a timestamp TSa to identify a size of a matching original packet, its place in the sequence of original packets and, thereby, its departure timestamp TSd, thus giving rise to a plurality of timestamp pairs (TSd; TSa).
