Abstract: Data frames are converted to a format suitable for transparent, flexible concatenated transport such that a network element not supporting flexible concatenation may transparently pass the data frames. Flexible concatenation involves nonstandard data frames such as an STS-4c or an STS-Nc in which the time slots do not occupy rigidly defined contiguous time slots. In transparent flexible concatenation, the pointer from the parent time slot is used for each of the child time slots and the concatenation identifier is set to indicate no concatenation. In this way, the concatenated data appears to be a series of conventional STS-1s such that pointer processing may be successfully accomplished even by a network element not capable of handling non-standard concatenations. A downstream receive framer reconstructs the original STS-Nc based on the N STS-1s and a concatenation table the contents of which are shared between the transmit framer and the downstream receive framer.

Abstract translation: 数据帧被转换成适合于透明，灵活的级联传输的格式，使得不支持灵活级联的网络元件可以透明地传递数据帧。 灵活连接涉及非标准数据帧，例如STS-4C或STS-Nc，其中时隙不占用刚性定义的连续时隙。 在透明灵活连接中，父时隙中的指针用于每个子时隙，并且级联标识符被设置为指示不连接。 以这种方式，连接的数据似乎是一系列常规STS-1，使得即使由不能处理非标准级联的网络元件也可以成功地实现指针处理。 下行接收成帧器基于N STS-1s重建原始STS-Nc，并且在发送成帧器和下行接收成帧器之间共享其内容的级联表。

Abstract: Embodiments of the present invention provide for diverse routing of a plurality of data streams, representative of a client signal of an unknown format, across multiple communication paths of a digital optical network through the use of a marker embedded in the client signal which is then inserted into the client payload portion of a transport frame. The multiple communication paths include different signal and path attributes related to the optical signals which transport the data streams across the digital optical network, as well as the physical structure of the digital optical network itself, all leading to timing variations in the multiple communication paths. The digital optical network transports the plurality of data streams in the form of wavelength division multiplexed signals, or banded wavelength division multiplexed signals.
