摘要： A method and system are provided for continuously monitoring bandwidth utilization in real time on a backbone of a network. Prefixes using the highest traffic can be identified and additional bandwidth can be provisioned in the form of optical transponder wavelengths. The additional bandwidth can be an express path that passes directly through optical nodes (thereby bypassing transit network devices) to the destination optical node. A centralized controller can perform the monitoring of the network devices, decide that an express path needs to be generated, and control both the network device and the optical network nodes to generate the express path from the network device, through the optical network, to the destination network device. The controller can apply and remove IP static routes and IP addresses associated with an express path. Additionally, the controller can request the setup or tear-down of an optical wavelength within the optical network.

摘要： A first optical module includes an optical transceiver and a chip. The optical transceiver, subsequent to completion of link training of an in-band transmission link between the first optical module and a host device, waits for a second optical module to come up including transmitting a first awake signal from the first optical module to the second optical module, and receives a second awake signal from the second optical module when the second optical module is up. The chip i) based on a first out-of-band signal transmitted via an out-of-band link, performs the link training of the in-band transmission link independently of an in-band reception link between the first optical module and the host device, and ii) based on the second awake signal and a second out-of-band signal transmitted via the out-of-band link, performs link training of the in-band reception link independent of the in-band transmission link.

摘要： An apparatus includes a memory and a processor operatively coupled to the memory. The processor is configured to partition a set of ports of an optical multiplexer into a set of port groups including a first port group having a first set of ports and a second port group having a second set of ports mutually exclusive from the first set of ports. The processor is configured to associate the first port group with a first router and associate the second port group with a second router. When the optical multiplexer is operatively coupled to the first router and the second router, the first router is operatively coupled to the optical multiplexer via the first set of ports and not the second set of ports, and the second router is operatively coupled to the optical multiplexer via the second set of ports and not the first set of ports.

摘要： A data center includes a wavelength source, a first optical component, a first communications device, and a second communications device. The wavelength source is configured to generate an N-wavelength laser beam. The first port of the first optical component is configured to receive an M-wavelength laser beam from the wavelength source. The second port of the first optical component is configured to send the M-wavelength laser beam to the first communications device. The M-wavelength laser beam includes at least a first-wavelength laser beam. The second port of the first optical component is further configured to receive a modulated first optical signal from the first communications device, the modulated first optical signal is obtained after the first communications device modulates a service signal onto the first-wavelength laser beam. The third port of the first optical component is configured to send the modulated first optical signal to the second communications device.

摘要： An optical network element for a hardware configured optical network includes a first optical port that receives an input optical signal comprising receive control information from the hardware configured optical network. A demodulator optically coupled to the first optical port decodes the receive control information for configuring the optical network element. A modulator having an electrical modulation input that receives transmit control information imparts a modulation onto an optical carrier thereby generating a transmit optical control signal representing the transmit control information. A second optical port transmits the transmit optical control signal representing the transmit control information to the hardware configured optical network.
