Channelized framing structure to support constant bit rate traffic in an optical network environment

One or more non-transitory computer readable storage media encoded with instructions that, when executed by a processor, cause the processor to perform operations, comprising:

• mapping at least one of Ethernet data or optical transport network (OTN) data into a flexible optical transport network (OTN) optimized for Ethernet (FlexO-Xe) frame structure including 5 Gigabit per second time slot blocks for a predetermined number of channelized data frames to support transmission data rates greater than 1 Terabit per second, wherein the mapping includes:
• mapping the Ethernet data into groups of a predetermined number of time slot blocks provided over each of the predetermined number of channelized data frames;
• and
• mapping the OTN data into the groups of the predetermined number of time slot blocks provided over a predetermined subset of channelized data frames of the predetermined number of channelized data frames and mapping additional OTN data associated with each of the predetermined subset of channelized data frames into an additional time slot block of at least one remaining channelized data frame of the predetermined number of channelized data frames;
• and
• transmitting at least one of the Ethernet data or the OTN data via an optical network link.

An apparatus comprising:

• at least one memory element for storing data;
• and
• at least one processor for executing instructions associated with the data, wherein executing the instructions causes the apparatus to perform operations, comprising:
• mapping at least one of Ethernet data or optical transport network (OTN) data into a flexible optical transport network (OTN) optimized for Ethernet (FlexO-Xe) frame structure including 5 Gigabit per second time slot blocks for a predetermined number of channelized data frames to support transmission data rates greater than 1 Terabit per second, wherein the mapping includes:
• mapping the Ethernet data into groups of a predetermined number of time slot blocks provided over each of the predetermined number of channelized data frames;
• and
• mapping the OTN data into the groups of the predetermined number of time slot blocks provided over a predetermined subset of channelized data frames of the predetermined number of channelized data frames and mapping additional OTN data associated with each of the predetermined subset of channelized data frames into an additional time slot block of at least one remaining channelized data frame of the predetermined number of channelized data frames;
• and
• transmitting at least one of the Ethernet data or the OTN data via an optical network link.
