摘要： In a decoder implementing a belief propagation algorithm for iteratively decoding a Low Density Parity Check (LDPC) encoded data block, a method of computing messages to be sent by a first node of the decoder to at least one neighbour node of the decoder. The method comprises: processing messages received by the first node to remove an echo of a previous message sent by the first node to the at least one neighbour node in a previous iteration, to yield corresponding modified messages; computing a message for a current iteration using the modified messages; and broadcasting the computed message for the current iteration to each of the at least one neighbour nodes.

摘要： A network interface includes at least one physical memory, at least one client port, at least one processor accessing the at least one physical memory, and at least one network port. The client port receives data blocks which contain a quantity of bits from at least one first client computer system. The processor temporarily stores the data blocks in the at least one physical memory. The processor interacts with the physical memory and compresses the data blocks to reduce the quantity of bits. The processor further interacts with the physical memory such that the compressed data blocks are encrypted to produce encrypted frames. The at least one network port transmits the encrypted frames across a communication network.

摘要： A synchronizer/de-synchronizer maps continuous format signals of an arbitrary rate into frames of pre-selected single common rate, such as SONET frames, with no bits changed and very little jitter or wander added. In this way, the continuous format signal may be carried transparently as a tributary of a SONET network. Each frame comprises a definite number of fixed stuff bits, including transport overhead bits and reminder fixed stuff bits. A frame also comprises an adjustable number of adaptive stuff bits, resulting from the phase difference between the arbitrary rate and the common rate. A mapping function is performed in a tributary unit shelf of a SONET transport shelf, and the reverse mapping function is performed in a similar way at the far end of a SONET connection. The stuff bits are spread uniformly within the frame.
摘要翻译：同步器/去同步器将任意速率的连续格式信号映射到预先选择的单个公共速率的帧，例如SONET帧，而不改变位，并且添加非常小的抖动或漂移。以这种方式，连续格式信号可以作为SONET网络的支路透明地携带。每个帧包括一定数量的固定填充位，包括传输开销位和提醒固定填充位。帧还包括可调数量的自适应填充位，由任意速率和公共速率之间的相位差产生。在SONET传输架的支路单元架中执行映射功能，并且以类似的方式在SONET连接的远端执行反向映射功能。填充位在帧内均匀分布。
