    摘要: Method and apparatus of a network configuration configured to permit a dense wavelength division multiplexing (“DWDM”) element to connect to a storage server, an Internet Protocol (“IP”) router, and DWDM network are disclosed. The configuration includes the DWDM network, storage area network (“SAN”) server, IP router, and optical transport network (“OTN”) switch. While the DWDM network transports information via optical fibers, the DWDM switch is coupled to the DWDM network for transporting optical signals. The SAN server is coupled to a port of the DWDM switch and is configured to store data at a remote location. The IP router which is coupled to the DWDM switch facilitates IP traffic between a user and the DWDM network. The OTN switch, coupled to the first DWDM switch, is capable of processing at least a portion of the optical signals.

    摘要: The disclosed methods and apparatuses provide a unique and cost efficient approach to using traffic channels of an optical mesh network, and sometimes optical supervisory channels, for carrying timing information (e.g., BITS timing signals), thus eliminating the need to use external BITS sources at remote add/drop nodes of a network. Planning the distribution of timing in such an optical mesh network includes identifying in the network a source node associated with an external timing source, identifying optical light paths between nodes in the network, and, for nodes other than the source node, selecting optical light paths originating either directly or indirectly from the source node to use to derive timing information.

    摘要: Optical regeneration is expensive to implement and maintain. A method or corresponding apparatus in an example embodiment of the present invention enables a user to plan an optical regeneration in a network with a reduction of optical regeneration compared to unplanned deployment. An optical regeneration planning tool according to an example embodiment of the present invention can graphically display a representation of a network topology with optical regeneration sites and enable the user to plan optical regenerations at a subset of the sites as a function of characteristics of models of optical network elements and paths within the network topology. Through use of the optical regeneration planning tool, a service provider can save on network deployment and future servicing of optical regeneration equipment.

    摘要: Fault management and providing resilience against failures is an useful for many networks. Protection techniques are used to ensure that networks can continue to provide reliable service and to provide redundant capacity within a network to reroute traffic in presence of a failure. A method or corresponding apparatus according to an example embodiment of the present invention relates to determining availability in a network. The example embodiment calculates availability on a per demand basis for working, protection, and restoration paths among all demands in the network and reports the availability. The reported availability may be used to plan and suggest changes to the network or to recommend addition of equipment to improve the availability of the network while ensuring that service level agreements are satisfied.

    摘要: Signals propagating in wavelength division multiplexing (WDM) optical networks suffer from loss, which decreases optical signal-to-noise ratios (OSNRs) and degrades a quality of received transmissions. Present methods of boosting OSNRs involve regeneration using transponders, which scale in complexity with the number of WDM channels. Optical amplifiers may boost signal strength, but amplified spontaneous emission (ASE) noise often reduces OSNR despite increases in signal strength, although changing the amplifier operating settings may reduce emitted ASE noise power. A method or corresponding apparatus in an example embodiment of the present invention provides a planning tool for deploying optical amplifiers in an optical network in a manner that reduces the need for optical regeneration, reducing cost and complexity of the deployed network. In one embodiment, the disclosed planning tool may substitute models of high-gain amplifiers operating at low settings for models of low-gain amplifiers operating at high settings.
