Embodiment Construction
[0038] In order to make the objects, technical solutions, and advantages of the present invention more clearly, the technical solutions in the embodiments of the present invention will be described in contemplation in the embodiment of the present invention. It is an embodiment of the invention, not all of the embodiments.
[0039] figure 1 A schematic diagram of flexible Ethernet overhead to the OIF standard organization; figure 1 Indicated. Data transfer in flexible Ethernet is based on time division multiplexing mechanism. Alternatively, a 100 g of the PhysicalLayer, referred to as a PhysicalLayer, referred to as a PhysicalLayer, a referred to, with a PhysicalLayer, a referred to, and a 100 g of a slot (Solt) of 20 5 g of particle size can be divided. Accordingly, a flexible Ethernet data frame includes a plurality of overhead frames and a plurality of data blocks. In a micro-age, there is a 1023 × 20 data code block, which is repeated 1023 times for 20 slots. Insert a cost bl...

The invention provides a flexible Ethernet management channel extension method and equipment, and relates to the technical field of communication. The method for extending the flexible Ethernet management channel includes: a sending end device acquires a Flexible Ethernet (FlexE) 66-bit code block, and the flexible Ethernet 66-bit code block schedule information. The schedule information includes multiple micro-schedules, and each micro-schedule includes N data code blocks, and the N data code blocks are divided into M groups according to the order of the code blocks. In the first M‑1 group, an extension is inserted after each group of data code blocks Management code blocks, where N and M are integers greater than 1. The sending end device sends the flexible Ethernet 66-bit code block to the receiving end device. In the present invention, each micro-schedule is divided into M groups, and on the basis of not changing the insertion mode of the original FlexE overhead code block, an extended management code block for managing the channel is inserted after each group in the M-1 group, thereby Realize the expansion of the FlexE management channel and speed up the data transmission rate.
Description
Technical field [0001] The present invention relates to the field of communication technologies, and in particular, there is a flexible Ethernet management channel extension method and device. Background technique [0002] Flexible Ethernet, referred to as it has the characteristics of bandwidth, data isolation, perfect fit 5G (5th-GenerationNetWork, Fifth-generation mobile communication technology), is recognized by mainstream operators and suppliers . [0003] The difference between flexible Ethernet and traditional Ethernet is to flexibly Ethernet in MediaAccess Control, a Physical Coding Sublayer, a referred to as a flexible Ethernet pad (Flexible Ethernet Shim) , Referred to as Flexe Shim). In the Optical Internetworking Forum, the Optical Internet Forum is defined to insert an 66B flexible Ethernet overhead block between 866B, 8 66B flexible Ethernet overhead blocks form a overhead frame. Only the 7th and 8th 66b blocks used in one overhead frame are used. Calculated, the b...
