Abstract: There is provided a technique of clock managing in a packet data network implementing a time-transfer protocol. The technique comprises: modifying, by the timing-server, a timestamp record to enable a controllable access to data informative of the least significant part of clock-informative data (CLSP data), wherein modifying the timestamp record comprises modifying the least significant part of the timestamp record (RLSP) to comprise the CLSP data in an encrypted form or to comprise values substituting, in a predefined manner, the CLSP data; transferring the modified timestamp record to all timing-clients, wherein CLSP data are transferred in a controllable access manner; enabling access to the CLSP data merely to authorized timing-clients among the plurality of timing-clients; and enabling the authorized timing-clients to obtain the CLSP data and synchronize the respective clocks using the CLSP data together with data informative of the most significant part of the clock-informative data.

Abstract: A computer-implemented method for reducing service disruption times in a network functions virtualization, NFV, network infrastructure includes at least one universal customer premise equipment, uCPE, having hardware resources used for running virtual network functions, VNFs, on virtual machines, VMs. In response to a request for substituting an implemented virtual network function, VNF, linked to other virtual network functions, VNFs, in a VNF service chain by another substitution VNF resource allocation ratios of available hardware resources of the universal customer premise equipment, uCPE, are automatically increased from a default value by oversubscription to provide the hardware resources required by the substitution VNF.

Abstract: A process for using a boot loader to load a set of boot commands to a device such as an embedded system before loading a system application. The process may use a combination of a read-only boot source and a pair of upgradable boot sources. Process also includes a power cycle to put system into a known state.
An alternative process may simply use a pair of upgradable boot sources. The processes are resilient to failed updates of an upgradable boot source. After a successful update of an upgradable boot source, a request for a power cycle causes the device to immediately enter a known state and use the updated upgradable boot source.

Abstract: Disclosed is a method for determining the link latency of an optical transmission link which includes an end node at each end and one or more pass-through nodes. Each pair of neighboring nodes is connected, at a connection port of each node, by an optical connecting path. Each pass-through node includes an optical pass-through path between its connection ports. The optical connecting paths and optical pass-through paths form an optical link path. A delimiter device includes a delimiter element provided at each connection port of each node. The delimiter element forms a demarcation within the optical link path. According to the method the following steps are carried out: measuring, for each pair of neighboring nodes, a section latency by transmitting a section probe signal from a first one of the pair of nodes to the second one of the pair of nodes; measuring, at the first node, a first time delay of a first reflection signal, which is created by the delimiter element of the delimiter device of the first node by reflecting a power portion of the section probe signal, and a second time delay of a second reflection signal, which is created by the delimiter element of the delimiter device of the second node by reflecting a power portion of the section probe signal received from the first node; and calculating the section latency as half the difference between the second time delay and the first time delay; determining, for each pass-through node either theoretically or by measurement, a pass-through latency of an internal optical pass-through path between the delimiter elements of the delimiter devices of the respective pass-through node; and adding all section latencies and pass-through latencies in order to obtain the link latency of the optical link path.

Abstract: A method for removing static differential delays resulting from an independent transport of the client signals of a client signal bundle through an optical transport network, OTN, which comprises OTN mappers mapping received client signals to ODU signals transported to OTN demappers demapping received ODU signals to client signals, wherein a process slave, PS, at the OTN mapper end of said OTN network supplies continuously or in response to a received request information about timing relations between the client signals of said client signal bundle to a process master, PM, at the OTN demapper end of said OTN network used by the process master, PM, to remove the static differential delays between the client signals of the respective client signal bundle.

Abstract: A photonic chip includes a connecting means, a substrate, and a waveguide layer. The photonic integrated waveguide and the optical fiber each have a front end portion. The connecting means includes a groove configured to receive the front end portion of the optical fiber. The groove is essentially U-shaped in its cross section, and the groove has a bottom surface and two inner side surfaces. A least one of both inner side surfaces of the U-shaped groove has a coating of an elastic material configured to hold in place the optical fiber after it is inserted into the groove. The invention further relates to an optical device which includes a photonic chip and an optical fiber, as well as a method or production of such a photonic chip.

Abstract: A device for producing timing information comprises equipment (101) that extracts first preliminary timing information from a first circular polarized component of a radio signal and second preliminary timing information from a second circular polarized component of the radio signal. The second circular polarized component has an opposite handedness and a time-delay with respect to the first circular polarized component. The device comprises a processing system (102) that produces the timing information based on the first preliminary timing information and/or the second preliminary timing information, and uses stored correction data for reducing the effect of the time-delay on the timing information when using the second preliminary timing information for producing the timing information. Thus, the timing information corresponds to the first preliminary timing information also when the timing information is produced based on the second preliminary timing information.
