Abstract:
In general, techniques are described for providing diversity in simulation datasets during modeling. A device comprising a memory and a processor may be configured to perform the techniques. The memory may store simulation configuration files for conducting simulations of the network device within a test environment. The processor may conduct, based on the simulation configuration files, each of the simulations with respect to the network device to collect corresponding simulation datasets indicative of an operating state of the network device. The processor may determine a level of similarity between the simulation datasets, and select, responsive to a comparison of the level of similarity to a diversity threshold, a subset of the simulation datasets. The processor may generate, based on the selected subset of the simulation datasets, a model representative of the network device that predicts, responsive to configuration parameters for the network device, an operating state of the network device.
Abstract:
An access network includes an access device having an optical interface module that outputs a plurality of pairs of optical communication signals, each of the pairs of optical communication signals comprising a modulated optical transmit signal and an unmodulated optical receive signal, each of the pairs of optical communication signals having a different wavelength. A customer premise equipment (CPE) comprises an optical interface module to receive the modulated optical transmit signal and the unmodulated optical receive signal for any of the plurality of pairs of optical communication signals. The optical interface module includes a receive module to demodulate the modulated optical transmit signal into inbound symbols and a transmit module having an optical modulator and reflective optics to modulate the unmodulated optical receive signal in accordance with a data signal and reflect a modulated optical receive signal to communicate outbound data symbols to the access device.
Abstract:
Subscriber management and network service integration for an access network is described in which a centralized controller provides seamless end-to-end service from a network to access nodes. For example, a method includes dynamically establishing a control channel between the centralized controller and an access node, and establishing a transport label switched path (LSP) transport network packets between the access node and the network node. The access node sends, via the control channel, an endpoint indication message that indicates that an endpoint that has joined the network at the access node. The access node receives a pseudo wire request message via the control channel to install forwarding state for creating a pseudo wire for providing one or more network services to the endpoint. The access node receives a direct switch message via the control channel to configure the access node to map traffic received from the endpoint to the pseudo wire.
Abstract:
A system that processes single stream multicast data includes multiple queues, a dequeue engine, and/or a queue control engine. The queues temporarily store data. At least one of the queues stores single stream multicast data. A multicast count is associated with the single stream multicast data and corresponds to a number of destinations to which the single stream multicast data is to be sent. The dequeue engine dequeues data from the queues. If the data corresponds to the single stream multicast data, the dequeue engine examines the multicast count associated with the single stream multicast data and dequeues the single stream multicast data based on the multicast count. The queue control engine examines one of the queues to determine whether to drop data from the queue and marks the data based on a result of the determination.
Abstract:
An access network is described in which a centralized controller provides seamless end-to-end service from a core-facing edge of a service provider network through aggregation and access infrastructure out to access nodes located proximate the subscriber devices. The controller operates to provide a central configuration point for configuring aggregation nodes (AGs) of a network of the service provider so as to provide transport services to transport traffic between access nodes (AXs) and edge routers on opposite borders of the network.
Abstract:
In general, techniques are described for automated network device model creation using randomized test beds. A device comprising a processor may be configured to perform the techniques. The processor may generate, based on simulation configuration files, configuration objects for performing a plurality of simulation iterations with respect to the network device operating within a test environment. Each of the simulation iterations may be configured to randomly assign parameters within the test environment. The driver may conduct, based on the configuration objects, each of the simulation iterations within the test environment to collect simulation datasets representative of operating states of the network device. The analytics module may perform machine learning with respect to each of the simulation datasets to generate a model that predicts, responsive to configuration parameters, an operating state of the network device when configured with the configuration parameters for the network device.
