摘要：一种光传送网（OTN）中业务时钟透传的方法及系统，所述系统包括业务接入端和OTN网络接收端；所述方法包括：OTN网络接收端在接收到OTN帧后，对该OTN帧进行解映射操作，从中恢复出业务数据流后，对该业务数据流进行二级缓存操作，由第一缓存单元对该业务数据流进行均匀化处理后输出到第二缓存单元，所述第二缓存单元收到后以业务时钟输出该业务数据流。采用本发明后，业务数据流相对均匀地写入第二缓存单元中，这样就可以保证第二缓存单元中填充的数据相对稳定，产生的锁相环控制信号不会对锁相环进行大幅调整，从而可以保证恢复出的业务时钟质量相对较高，满足客户对业务时钟的相关指标要求。

摘要： A method and system for allowing data traffic from multiple interfaces to be processed using a common clock frequency. For one embodiment of the invention, data is received from two or more data channels of a communications network, each data channel having a maximum channel frequency. The data from the two or more data channels is combined and the combined data is processed at one or more functional blocks of the communications network, wherein each functional block operates at a clock speed sufficient to process data at a rate greater than the aggregate maximum channel frequency of the two or more data channels. For one embodiment a portion of the data is deleted from each of the data channels to obtain an aggregate maximum channel frequency of the two or inore data channels that is less than an operational frequency of the one or more functional blocks.

摘要： The invention features a multi-mode framer/pointer processor apparatus that is able to selectively accomodate one or more OC-192 data streams as well as an OC-768 data stream. The framer/pointer processor is coupled to the input of a data processing apparatus receiving data streams that have been transmitted over an optical SONET network and identifies within the received data stream a payload and an overhead portion. The received data streams are SONET frames and the path overhead portions transport overhead (TOH) portion of the SONET frames. All functions of the framer/pointer processir are integrated on a single chip integrated circuit.

摘要： This application relates to a method for synchronizing multiple nodes in an optical network through which at least one client data packet is transmitted. In particular, the at least one client packet is synchronously placed in one or more containers that are routed through the network. A container is associated with a time slot allocated for transmitting the container through the network and comprises a container identification number in a container header of the container to identify the time slot associated with the container. In particular, the one or more containers have respective one or more container identification numbers are arranged in sequence using a cyclic numbering scheme that repeats a same container identification number after a container cycle has been completed, so that the one or more containers are transmitted in a cyclic order of the one or more respective container identification numbers. The method comprises receiving an incoming container at a node from an upstream node. The method also comprises identifying a numbering offset indicative of a difference between a container identification number of the received incoming container and an internal counter value of the node. It is noted that the internal counter value may be maintained to indicate an expected container identification number of a next container to be received by the node. The method further comprises determining a frequency control signal for a local transmit clock of the node based on the numbering offset. The method also comprises adjusting a local transmit clock signal of the node based on the frequency control signal.

摘要： In a system for transmitting a digital data stream, wherein the data are formatted into a series of virtual containers (VCs) and routed through several paths in parallel - a method for hitless switching between the versions that arrive over the various paths. The method includes inserting into each VC an identifying code and a parity checksum, or, in the case of a multi-segment VC, a checksum for each segment. At the node of convergence the method calls for delaying any received version by a respective amount, such that will cause all the versions to become aligned in time, so that VCs having the same identifying code flow synchronously byte-for-byte. For each received version and for each VC or segment, parity is calculated and compared with the corresponding checksum, to determine a respective error level. The error levels are compared among the versions for each successive VC or segment and the VC or segment with the lowest error level is selected and inserted into an output data stream. Whenever the version, from which a next VC or segment is selected, changes, switching occurs at the boundary between successive VCs or segments, thus avoiding hits.
摘要翻译：在用于发送数字数据流的系统中，其中数据被格式化成一系列虚拟容器（VC）并且并行地通过若干路径路由 - 用于通过各种路径到达的版本之间的无连接切换的方法。该方法包括在每个VC中插入识别码和奇偶校验和，或者在多段VC的情况下插入每个段的校验和。在收敛节点，该方法要求将任何接收到的版本延迟相应的量，这样将导致所有版本在时间上对准，使得具有相同标识码的VC以字节为单位流同步。对于每个接收的版本和每个VC或段，计算奇偶校验并与对应的校验和进行比较，以确定相应的错误级别。在每个连续VC或段的版本之间比较错误级别，并选择具有最低错误级别的VC或段并将其插入到输出数据流中。每当选择下一个VC或段的版本发生变化时，切换将发生在连续VC或段之间的边界处，从而避免命中。

摘要： The continuity of divided multiplex signals is maintained and an original large-capacity multiplex signal is restored to realize efficient large-capacity transmission. A signal dividing means (11) divides a multiplex signal and generates a plurality of division signals of STS or STM transmission interface type. An assurance information adding means (12) adds assurance information which assures the continuity of the division signals to the division signals to generate a transmission signal. A signal transmitting means (13) transmits the transmission signal via a transmission path of a transmission interface type. A signal receiving means (21) receives the transmission signal. A signal restoring means (22) assembles the division signals in accordance with the assurance information and restores the multiplex signal.
