摘要： Methods and apparatus for dynamic bandwidth provisioning in wavelength division multiplexing (WDM) optical ring networks. A plurality of nodes within the network are configured to transmit optical signals at variable wavelengths and receive optical signals at a predetermined wavelength. A network management system computer may be provided to communicate with the network nodes to direct the wavelengths at which each node transmits and receives. A series of one or more lightpath rings within the network are defined by selecting a first plurality of network nodes to provide a channel to support the optical transmission of a communication signal therebetween having a first bandwidth allocation. Each network node within the first plurality of network nodes is instructed upon command by the network management system to transmit an optical signal at a predetermined wavelength that is to be received by only one other network node within the first plurality of network nodes to form a first series of optical links therebetween which in the aggregate form the lightpath ring. Each network node within the second plurality of network nodes is instructed upon command by the network management system to transmit an optical signal at a predetermined wavelength that is to be received by only one other network node within the second plurality of network nodes to form a second series of optical links therebetween which in the aggregate reforms the lightpath ring. Accordingly, the lightpath ring may be reformed upon command by the network management system by altering the number of network nodes within the first plurality of network nodes to define a second plurality of network nodes which dynamically provides the channel with a different bandwidth allocation.

摘要： Methods and apparatuses of opening ring optical networks are disclosed, as optical nodes, for example open intercepts and closed intercepts, supporting open ring optical networks. Open ring optical networks can prevent optical wavelengths from traversing an optical node in an optically transparent network. Optical feedback can be prevented in open ring optical networks, for exymple optical networks containing optical amplifiers. Coherent crosstalk can be prevented in open ring optical networks. Some open ring networks further allow standard communication protection techniques that are typically associated with rings which are topologically closed. These network architectures can enable low cost-of-maintenace bandwidth upgrades to the entire network.
