Abstract: A data stream with a given data rate is distributed into a plurality of virtual lanes or streams, each with a lower data rate than the data stream. Virtual lanes permit the use of lower cost electronics at the optical-electrical conversion points. Security information is generated that includes a unique initialization vector. The security information is distributed or allocated across some or all of the of the virtual data streams in a virtual lane alignment marker in a portion of the alignment marker used to maintain direct current (DC) transmission balance, but that otherwise does not provide useful information.

Abstract: Techniques are described herein for enabling mapping of virtual lanes for data streams for transmission over an optical transport network (OTN). Line encoded data blocks of a first data stream are distributed at an endpoint device in an OTN. The line encoded data blocks of the first data stream are distributed across a plurality of second data streams such that the second data streams can be processed at a lower data rate than a data rate associated with the first data stream. A transcoding operation is performed on the data packets of each of the second data streams to generate transcoded data packets. The transcoded data packets are processed such that the transcoded data packets of each of the second data streams can be sent over the OTN at the lower data rate.
Abstract translation: 这里描述了用于实现用于数据流的虚拟通道的映射以便在光传输网络（OTN）上传输的技术。 第一数据流的线路编码数据块分布在OTN中的端点设备处。 第一数据流的行编码数据块被分布在多个第二数据流上，使得可以以比与第一数据流相关联的数据速率更低的数据速率处理第二数据流。 对每个第二数据流的数据分组执行代码转换操作，以生成代码转换的数据分组。 对经转码的数据分组进行处理，使得每个第二数据流的经转码的数据分组可以以较低的数据速率在OTN上发送。

Abstract: An Optical Transport Network (OTN) frame comprises an optical channel payload unit that is divided into a plurality of timeslots. This OTN frame is received at a transmitter and the timeslots are grouped into blocks of timeslots. Two or more blocks of timeslots are selected for encryption and are encrypted/authenticated in parallel to generate an encrypted OTN frame in which only certain blocks of timeslots are encrypted.
Abstract translation: 光传输网络（OTN）帧包括被分成多个时隙的光信道有效载荷单元。 该OTN帧在发射机处被接收，时隙被分组成时隙块。 选择两个或更多个时隙块进行加密，并且并行加密/认证，以生成加密的OTN帧，其中仅某些时隙块被加密。
