Abstract: A method generates, from an input data stream, multiple lanes of a physical coding sublayer (PCS) signal. The method converts the data stream to a sequence of bit blocks, and periodically inserts into the sequence of bit blocks an alignment marker (AM) group including multiple individual alignment markers for respective ones of the multiple lanes. The method adds security protection to each bit block according to a security protocol to produce a sequence of protected bit blocks, and modifies each AM group with security information to be used by the security protocol to remove the security protection added to the sequence of protected bit blocks. The method applies forward error correction to the sequence of protected bit blocks and the modified AM groups to produce forward error correction codewords, and produces the multiple lanes from the codewords. The method transmits the multiple lanes over an optical link.

Abstract: An optical frame is received over an optical link within an optical network. The optical frame contains a payload of aggregated data, an alignment value, and a bit interleaved parity value. The content of the optical frame is aligned based on the alignment value. The bit interleaved parity value is monitored. In response to the monitoring, a transmission quality of the transmission link is determined.

Abstract: At a source network device, data is compiled into a plurality of data blocks for transmission in a data frame over a network to a destination network device. The plurality of data blocks are arranged into a plurality of data block groups such that each data block group comprises a predetermined number of data blocks. Encryption information is generated for each of the plurality of data blocks groups. The encryption information identifies an encryption key for each of the plurality of data block groups. Overhead data configured to allow the destination network device to align and decode the data frame is generated. The data frame is transmitted from the source network device to the destination network device such that the encryption information for each of the plurality of data block groups is transmitted consecutively with a respective data block group, and a portion of the overhead data is transmitted prior to each consecutive transmission of encryption information with a data block group.
