摘要： There is provided a transmission system, a transmission method, and a transmission device that make it possible to inhibit deterioration in quality of transmission signals while reducing the number of times of compensation on transmission signals in a case where a plurality of devices is connected in a daisy chain. The transmission system includes a plurality of sub devices and a main device that are connected in a daisy chain. The main device includes a main connector connected to the first sub device of the plurality of sub devices, the main connector being configured to output transmission signals of a plurality of channels. The plurality of sub devices each includes a first sub connector connected to a preceding device, the first sub connector being configured to receive the transmission signals, a compensation unit disposed to correspond to a channel obtained as a result of thinning out, at predetermined intervals, channels other than a channel of an own device signal used by the sub device to which the compensation unit belongs, the compensation unit being configured to perform compensation on the transmission signals, and a second sub connector configured to shift channels of the transmission signals received from the preceding device other than the own device signal by the number of channels of the own device signal and output the transmission signals. The present technology is applicable to, for example, a multi-monitor system.

摘要： The disclosure provides methods, apparatus and computer-readable media for synchronization over an optical network. A method comprises: receiving, from a client, a request to initiate a synchronization service for a client node coupled to the optical communication network; and, in response to the request, establishing a synchronization service to the client node via a virtual synchronization network utilizing the optical communication network. The synchronization service utilizes a bidirectional optical channel established via the optical communication network for the transmission of synchronization data for the client.

摘要： Recovering or restarting an execution instance. In response to detecting that a particular execution instance, in which a cable modem termination system (CMTS) software application, an optical line terminal (OLT) software application, and/or broadband network gateway (BNG) software application has failed, restarting the execution instance without adding any downstream service flow classifiers to the instance or configuring any entries of an access control list for the instance. After restarting the execution instance, over time adjusting the configuration of the instance to add one or more downstream service flow classifiers or access control list entries such that the instance can provide additional services, beyond a default service flow, to cable modems or optical network units. Support for voice calls may be initially added to the execution instance upon startup. Required time to register cable modems or optical network units with the execution instance is advantageously reduced while maintaining quality of service.

摘要： One embodiment described herein provides a system for distributed fiber sensing. The system can include a plurality of network elements (NEs) in an optical transport network (OTN) and a control-and-management module coupled to the NEs. A respective network element (NE) can include a first wavelength coupler configured to separate an optical supervisory channel (OSC) signal from a data-carrying signal received from a fiber span, a polarization-measurement unit configured to perform a polarization measurement on the OSC signal, and a transmitter configured to transmit an outcome of the polarization measurement to the control-and-management module, thereby facilitating distributed fiber sensing based on the outcome of the polarization measurement.

摘要： A framework for virtual network element of optical access networking has been designed to provide a cloud-residing core system (i.e., Mobile core controller or SDN controller) for running higher layers without requiring dedicated hardware at the edge of the network. In this framework, a service operator can create multiple optical access network connections for serving a single or multiple types of wired or wireless subscriber by programming (via software) optical ports of a Virtual Optical Edge Device to perform the desired MAC and/or PHY layer of a selected optical protocol. The Virtual Optical Edge Device in turn performs the desired PHY function or MAC and PHY function of selected protocol per each southbound port. The Virtual Optical Edge Device performs data abstraction function on all data associated with southbound ports and presents the core network a unified API via its northbound ports.
