摘要:
In one example, a network controller manages a network having many network devices. Network devices can receive the timing flow port role assignments from the network controller based on the controller's global view of the network topology. The controller can also calculate timing offsets to be applied to the network devices, based on timestamp information obtained by the network devices via exchanging time synchronization protocol messages, and the controller can update time clocks on all of the network devices within a single window of time, based on a timing offsets calculated in single iteration of calculations.
摘要:
A mesh network of wired and/or wireless nodes is described in which a centralized controller provides seamless end-to-end service from the edge of the mesh network to mesh nodes located proximate to subscriber devices. The controller operates to provide a central configuration point for configuring forwarding planes of the mesh nodes of the mesh network, so as to set up transport data channels to transport traffic from the edge nodes via the mesh nodes to the subscriber devices.
摘要:
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.
