    • Provided are a method, system, computer storage device, and storage area network for maintaining a communication path from a host to a storage subsystem in a network. A storage subsystem controls data transfer and access to a storage devices in a network including a switch and a host. A topological storage stores topological coupling relationship between the host and the switch and a topological coupling relationship between the switch and the storage subsystem. In response to determining a failed path, the storage subsystem determines a first port on the storage subsystem in the failed path. The storage subsystem determines from the topology storage the topological coupling relationships between the host and the switch and the switch and the storage subsystem. The storage subsystem redirects, based on the topological coupling relationships, a message sent to the first port of the storage subsystem to an operational second port in the storage subsystem.

    • Various embodiments of the present invention provide methods and apparatuses for multi-level layer decoding of non-binary LDPC codes. For example, an apparatus is disclosed for layer decoding of multi-level low density parity check encoded data. The apparatus includes a low density parity check decoder operable to perform layered decoding of a plurality of circulant submatrices from an H matrix. The apparatus also includes a parity check calculator connected to the low density parity check decoder, operable to detect whether a stopping criterion has been met in the low density parity check decoder. The low density parity check decoder is also operable to end a decoding operation at less than a maximum number of iterations when the stopping criterion is met.
    • 本发明的各种实施例提供了用于非二进制LDPC码的多级层解码的方法和装置。 例如,公开了用于多级低密度奇偶校验编码数据的层解码的装置。 该装置包括低密度奇偶校验解码器,可操作以从H矩阵执行多个循环子矩阵的分层解码。 该装置还包括连接到低密度奇偶校验解码器的奇偶校验计算器,可操作以检测低密度奇偶校验解码器中是否已经满足停止标准。 当满足停止标准时,低密度奇偶校验解码器还可操作以小于最大迭代次数来结束解码操作。
