摘要： A high capacity network comprises a plurality of edge nodes with asymmetrical connections to a plurality of switch planes, each switch plane comprising fully meshed fast-switching optical switch units. Upstream wavelength channels from each source edge node connect to different switch planes in a manner which ensures that upstream wavelength channels from any two edge nodes connect to a common switch unit in at most a predefined number, preferably one, of switch planes. Thus, switch units in different switch planes connect to upstream channels from orthogonal subsets of source edge nodes. In contrast, downstream wavelength channels from a switch unit in each switch plane connect to one set of sink edge nodes. In an alternate arrangement, the upstream and downstream asymmetry may be reversed.

摘要： The present invention relates to controlling wavelength switching in a plurality of nodes that are provided to increase the distance of signal transmission in inverse MUX transmission in which a high-speed line is divided into a plurality of low-speed lines for transmission. A maximum skew occurring between adjacent nodes is measured, and switching of wavelength channels is performed in one or a plurality of nodes on the basis of the measured maximum skew to keep the skew of the entire inverse MUX transmission system at or below a prescribed value. The optical communication device is provided with an NNI functional block to which high-speed lines on the transmission channel side are connected, and a UNI functional block to which low-speed lines on the client side are connected.

摘要： Switching architectures for WDM mesh and ring network nodes are presented. In mesh networks, the switching architectures have multiple levels—a network level having wavelength routers for add, drop and pass-through functions, an intermediate level having device units which handle add and drop signals, and a local level having port units for receiving signals dropped from the network and transmitting signals to be added to the network. The intermediate level device units are selected and arranged for performance and cost considerations. The multilevel architecture also permits the design of reconfigurable optical add/drop multiplexers for ring network nodes, the easy expansion of ring networks into mesh networks, and the accommodation of protection mechanisms in ring networks.

摘要： In a known wavelength multiplexer, optical signals to pass are passed with their wavelengths held identical. Therefore, unless an unused wavelength common to all zones exists in case of setting an optical channel, the channel cannot be set. According to the present invention, a drop/add type wavelength multiplexer includes a wavelength converting section (50 in FIG. 5) which converts the wavelengths of optical signals to pass from the input side of the multiplexer to the output side thereof. In a network employing the wavelength multiplexers at individual nodes, a new optical channel can be easily set by utilizing wavelengths not used at the nodes.

摘要： The design of optical telecommunication networks is such that there is provision of end-to-end path restoration to specified demands under up to two links or nodes failures. Restoration routes are provided on Path Protecting Preconfigured Cycles (PP-PCs), where each demand is assigned one or two restoration routes and restoration wavelengths on a segment of one cycle. Splitting of demand across multiple restoration routes is not allowed. All restoration routes and restoration wavelengths are predetermined where multiple demands may share restoration wavelengths without resorting to intermediate switching or wavelength conversions along restoration routes. First, numerous candidate PP-PCs are generated. Assignment of demands with common failure scenarios are allowed, under certain conditions, to the same PP-PC. Next, a set of PP-PCs is selected from among the candidates, while minimizing total reserved restoration wavelengths cost and ensuring that all demands are protected as required. Finally, conflicts of wavelength assignments are resolved.

摘要： A system, device, and method for managing communication services in an optical communication system utilizes a optical service agent (OSA) that operates within the domain of the network user and manages various communication services on behalf of the network user. The OSA interacts with the optical communication network to obtain various communication services and manages those communication services for the network user based upon predetermined parameters defined by the network user. An authenticated auto-discovery mechanism is used to automatically identify and authenticate OSA-enabled users and to distribute information between peer OSA-enabled users. A peer-to-peer signaling mechanism is used to extend OSA functionality to OSA-enabled users that do not interface directly with the optical communication network.
