Abstract
Systems and methods for controlling network configurations or assignments are provided. A method, according to one implementation, includes a step of calculating transmission characteristics between each pair of a plurality of pairs of modems at opposite ends of a Dense Wavelength-Division Multiplexing (DWDM) transport link using specifications of the modems measured during production. The method also includes the step of selecting a pair of modems from the plurality of pairs of modems based on results obtained by calculating the transmission characteristics and based on one or more user-defined service requests.
Claims19
A system comprising:
- a processing device, and
- a memory device configured to store a computer program having instructions that, when executed, enable the processing device to
- calculate transmission characteristics between each pair of a plurality of pairs of modems at opposite ends of a Dense Wavelength-Division Multiplexing (DWDM) transport link using specifications of the modems measured during production, and
- select a pair of modems from the plurality of pairs of modems based on results obtained by calculating the transmission characteristics and based on one or more user-defined service requests,
- wherein the pair of modems are selected based on reach that includes a length of a fiber span between the pair of modems, capacity that is determined by a line rate of the pair of modems, and channel spacing in a gridless spectrum network where the channel spacing determines how close adjacent channels are in the gridless spectrum network, wherein the pair of modems provide optical transmission therebetween.
A system comprising:
- a processing device, and
- a memory device configured to store a computer program having instructions that, when executed, enable the processing device to
- calculate transmission characteristics between each pair of a plurality of pairs of modems at opposite ends of a Dense Wavelength-Division Multiplexing (DWDM) transport link using specifications of the modems measured during production,
- select a pair of modems from the plurality of pairs of modems based on results obtained by calculating the transmission characteristics and based on one or more user-defined service requests, and
- insert a channel associated with the selected pair of modems into an elastic spectrum when a receiver Signal-to-Noise Ratio (SNR) at the pair of modems meets specific criteria based on associated cross-talk and jitter penalties.
A system comprising:
- a processing device, and
- a memory device configured to store a computer program having instructions that, when executed, enable the processing device to
- calculate transmission characteristics between each pair of a plurality of pairs of modems at opposite ends of a Dense Wavelength-Division Multiplexing (DWDM) transport link using specifications of the modems measured during production,
- select a pair of modems from the plurality of pairs of modems based on results obtained by calculating the transmission characteristics and based on one or more user-defined service requests,
- wherein the specifications of transmitter components and receiver components of the modems are measured in the production and populated in a modem database, including generating polynomials to fit the transmitter components and receiver components to model an optical network.
