摘要： In an optical switching apparatus having redundantly-arranged optical switches, a route switching operation mode, an autonomic redundant switching operation mode and a compulsory redundant switching operation mode are discriminated from one another so that these operation modes are prevented from being executed at the same time, and also proper mask processing is performed at every switching operation mode. Therefore, emission of an undesired alarm and thus occurrence of malfunction when each switching operation is carried out can be prevented.

摘要： Whether in a SONET or a dense-WDM (DWDM) transport environment, we can expect to see a continuance of the two main survivable architectures: ring and mesh. The differing advantages of these technologies has allowed both of them to find applications, although they are usually deployed and operate quite separately. To date, the problem of optimally combining ring and mesh technologies into a single integrated transport design remains largely unstudied. This patent document presents a planning principle and related optimization theory to strategically embed rings into a mesh network, with the purpose of obtaining a lower total design cost than that of either a pure-mesh or pure-ring design. The new design approach is based on a recently developed insight into the nature of spare capacity requirements in a mesh-restorable network. So-called “forcer” analysis identifies the spans that drive the dimensioning of spare quantities in the network. The main hypothesis is that strategic placement of rings onto these spans, can result in mesh sparing relief that more than pays for the cost of the rings. However, the very large number of possible ring placements and sizes, makes this a difficult combinatorial optimization problem. Both heuristic and Integer Programming approaches were used to solve the problem. Results show cases of hybrid designs that are 5 to 25% less costly than that of a pure mesh design, depending on the test network and the relative mesh-ring technology costs. The Integer Programming method worked well for networks with fewer nodes and spans, while the heuristic was needed to obtain good solutions for relatively larger networks.

摘要： An optical apparatus comprises a phase grating, an input-ring array, an output-ring array and an optical interconnect. The phase grating produces a modulated light beam for each of a plurality of processing elements. The modulated light beams have a plurality of light wavelengths. An input-ring array receives the plurality of data modulated light beams. An output-ring array outputs a light beam to each processing element. An optical interconnect transfers light from the input-ring array to the output ring array and uniquely rotates each wavelength of the transferred light.

摘要： An optical fiber network of WDM type comprises two fibers which carry light signals propagating in opposite direction and which are arranged in a ring configuration. In the ring, one standby link between two neighboring nodes is used if another link fails. An add and drop node, used in the network only for traffic between neighboring nodes, has band blocking filters connected in respective fibers between a drop coupler and an add coupler. A drop coupler takes out equal shares of the light power to be received through simple switches and bandpass filters in receivers. An add coupler adds new wavelength channels produced in transmitters in the node through multiplexers and simple switches. The switches are used for receiving and transmitting on the wavelength channels in correct directions depending on the location of the inactive link. Thus, the positions of two of the switches have to be changed when the inactive link is one of the two links directly connected to the node. Such a node has a minimun of in-line components, and particulary, a minimum of in-line filtering components.

摘要： A transmission unit and a failure recovery method with failure recover functions, which use limited network resources efficiently. A label table manager manages a label table which associates incoming labels related to incoming transmission data with outgoing labels related to outgoing transmission data. Based on the label table, a transmission controller performs label-switching of transmission data. A path set-up unit establishes a loopshaped protection path that includes a part or whole of transmission links of an existing working path and would allow transmission data to flow in the opposite direction to that of the working path. When a failure occurs, a failure recovery controller changes the association between the incoming and outgoing labels stored in the label table and switches the failed part of the working path to the loop-shaped protection path, thereby restoring the label-switched network.

摘要： As the performance of individual elements within parallel processing systems increases, increased communication capability between distributed processor and memory elements is required. There is great interest in using fiber optics to improve interconnect communication beyond that attainable using electronic technology. Several groups have considered WDM, star-coupled optical interconnects. The invention uses a fiber optic transceiver to provide low latency, high bandwidth channels for such interconnects using a robust multimode fiber technology. Instruction-level simulation is used to quantify the bandwidth, latency, and concurrency required for such interconnects to scale to 256 nodes, each operating at 1 GFLOPS performance. Performance scales have been shown to ≈100 GFLOPS for scientific application kernels using a small number of wavelengths (8 to 32), only one wavelength received per node, and achievable optoelectronic bandwidth and latency.

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.
