    摘要： A method, system and computer-usable medium are disclosed for managing storage system resources in a storage area network (SAN). A target data storage server registers itself within a storage area network (SAN) fabric to receive a Registered State Change Notification (RSCN) should a SCSI initiator become inactive. A SCSI initiator then requests reservation of a target LUN. In response, the target data server reserves the LUN for use by the SCSI initiator. If a RSCN is received by the target data storage server, then a GID_PN server request, which comprises the unique identifier of SCSI initiator, is generated after a predetermined time interval and a SAN fabric name server. If the name server's response to the GID_PN server request is positive, then the SCSI initiator was detected as being active and the target data storage server keeps the reservation for the LUN active for the SCSI initiator. Otherwise, the reservation for the LUN is released for use by other SCSI initiators.

    摘要： Fiber-optic communications systems are provided for optical communications networks. Fiber-optic communications links may be provided that use spans of transmission fiber to carry optical data signals on wavelength-division-multiplexing channels at different wavelengths between nodes. An apparatus and method are disclosed to use one optical light source per node to perform OTDR and LCV to satisfy safety concerns and accelerate the verification of the integrity of optical fiber links, before the application of high Raman laser powered light sources to a fiber link. A system using only one receiver per node is also disclosed.

    摘要： A multicast optical switch includes a free-space optical assembly of discrete splitters, cylindrical optics, and a linear array of reflective switching devices, such as microelectromechanical systems (MEMS) mirrors, to provide low-loss, high-performance multicast switching in a compact configuration. The assembly of optical splitters may include multiple planar lightwave circuit splitters or a multi-reflection beam splitter that includes a linear array of partially reflecting mirrors, each of a different reflectivity.

    摘要： A communication comprises a plurality of digital subscriber line (DSL) links, a first node having at least one application port configured for an elastic service and a plurality of DSL ports, and a second node having at least one application port configured for an elastic service and a plurality of DSL ports. Each of the first and second nodes is configured to interleave data received over the at least one application port across the plurality of DSL ports, each DSL port allocated a set of DSL timeslots for transport of the data received over the at least one application port. When a failure is detected on one of the DSL links, each of the first and second nodes is configured to interleave the data received over the at least one application port across the remaining DSL ports not connected to the failed DSL link without adjusting the set of DSL timeslots allocated to each of the remaining DSL ports for transport of the data from the at least one application port.
