    摘要: A communication system comprises a plurality of DSL links comprising a first group and second group of DSL links, each group comprising more than one DSL link. The communication system also comprises a first node and a second node each having at least one application port and a plurality of DSL ports. Each DSL port is coupled to a respective one of the DSL links such that the first and second nodes are communicatively coupled via the DSL links. Each of the first and second nodes is configured to interleave a first copy of data received over the respective application port across the first group and to interleave a second copy of the data across the second group. When a failure is detected on a DSL link in the first group, each of the first and second nodes is configured to switch from the first group to the second group.

    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: Disclosed herein are representative embodiments of methods, apparatus, and systems for performing diagnostic from signatures created during circuit testing. For example, in one exemplary method disclosed herein, a signature produced by a signature generator is received. In this embodiment, the signature corresponds to the circuit's response to no more than one test pattern. The signature is compared to entries of a fault dictionary, an entry of the fault dictionary is matched to the signature if the entry identifies a fault that explains the signature, and the fault is stored in a list of fault candidates.
