Detailed Description

In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

First, in order to facilitate understanding of the embodiments of the present invention, some terms or nouns referred to in the present invention will be explained as follows:

the Medium Access Control (MAC) sublayer is a specific sublayer on the data link layer of the ethernet network, and is used to solve the problem of allocation of the shared channel.

The Physical Layer (PHY) defines electrical and optical signals, line states, clock baselines, data codes and circuits, etc. required for data transmission and reception, and provides a standard interface to the data link Layer, mainly for processing analog signals in communication.

Flexible Ethernet (FlexE Ethernet, referred to as FlexE for short) is proposed by the optical internetworking forum, and a core processing logic layer (FlexE Shim layer) is added between a media access control sublayer (namely, an MAC layer) and a physical layer (namely, a PHY layer) of a standard Ethernet interface to realize rate decoupling of the MAC layer and the PHY layer, so that the mapping relationship between an entity of the MAC layer and the PHY layer is changed from 1 to m to n, and Flexible rate matching is realized. The Flexe general architecture comprises a service interface layer Flexe Client, a core processing logic layer Flexe Shim and a physical interface integration layer Flexe Group.

The Flexe clients correspond to various service interfaces observed outside the network, each Flexe Client can be flexibly configured according to broadband requirements, support Ethernet MAC data streams with various rates, and transmit the data streams to a Flexe Shim layer through a 64B/66B coding mode. The Flexe Shim is used as a logic layer inserted between an MAC layer and a PHY layer, and a time slot distribution mechanism based on a time slot distributor Calendar is used for realizing a core framework of a flexible Ethernet technology. The FlexE Group, essentially various ethernet PHY layers, defaults to pooling the bandwidth of the PHY layer to resources of 5G bandwidth granularity.

The FlexE technology realizes user service flow forwarding based on a physical layer through a time slot crossing technology, and lays a foundation for bearing ultra-low delay service, however, the low delay technology of the current FlexE technology still needs to be optimized. Taking fig. 1 as an example, fig. 1 is a schematic structural diagram of a communication system. The communication system may include a communication device PE1, a communication device P, and a communication device PE2. Take the interaction between the communication device PE1 and the communication device PE2 as an example. When a communication device PE1 (hereinafter, referred to as a transmitting device PE 1) transmits a signal to a communication device PE2 (hereinafter, referred to as a receiving device PE 2), the transmitting device PE1 generates a signal and transmits the signal to a communication device P (hereinafter, referred to as a forwarding device P), the forwarding device P receives and forwards the signal and transmits the signal to the receiving device PE2, and the receiving device PE2 analyzes the received signal to acquire data in the signal.

In the conventional flexible ethernet solution, a signal sending flow of the sending device PE1 is shown in fig. 2; the received signal flow of the receiving device PE2 is shown in fig. 3; the forwarding signal processing flow of the forwarding device P is shown in fig. 4, wherein each module in fig. 2 to fig. 4 corresponds to a program execution step. It can be easily found that two main problems exist in the current timeslot distribution mechanism based on Calendar Calendar in the flexible Ethernet (Flexe) technology:

(1) The overhead insertion is not related to the alignment mark insertion, so that the extraction processing of the overhead by the receiving end is complex and the time delay is high.

Taking a physical interface set FlexE Group composed of physical interfaces PHY with bandwidth of 100GE as an example, the flexible ethernet FlexE uniformly divides the bandwidth PHY of each physical interface into 20 5GE timeslots, and allocates available timeslots (slots) in the FlexE Group according to the bandwidth required by each service interface (FlexE Client) to form mapping from the service data stream (FlexE Client) to one or more timeslots.

The mechanism for inserting overhead is specifically: one 66B Overhead code block is inserted every 20 × 1023 66B (bits, binary) data code blocks, 8 consecutive Overhead code blocks form one Overhead Frame (Overhead Frame), and 32 Overhead frames form one Overhead MultiFrame (Overhead MultiFrame), thereby carrying a complete set of flexible ethernet FlexE control information. The specific insertion form is shown in fig. 5; the overhead code stores configuration information corresponding to each time slot, and a specific storage form is shown in fig. 6.

The insertion mechanism of the alignment mark is specifically as follows: a physical interface PHY with the bandwidth of 100GE distributes signals to 20 PCS data channels in a PCS layer, and inserts a 66B alignment mark code block into each 16383 data code blocks of 66B on each PCS data channel of a physical coding sublayer. A specific insertion pattern is shown in fig. 7, in which black code blocks are alignment mark code blocks and white code blocks are data code blocks. The overhead code blocks originally appearing in an Ethernet 100GE physical interface appear on 20 physical coding sublayer PCS data channels in turn according to a certain rule. The distribution of overhead code blocks over 20 physical coding sublayer PCS data channels is shown in fig. 8. As can be seen from fig. 8, the insertion position of the alignment mark is not associated with the insertion position of the overhead code block, so that when the receiving device PE2 receives the signal sent by the sending device PE1, after the alignment mark locking module processes the position of the 1 st overhead code block in the 256 overhead code blocks of the flexible ethernet FlexE is further locked, all data code blocks before the overhead code block is locked are invalid, and therefore, the added overhead code block locking module will have two negative effects: one is to add delay, which depends on the relative position of the 1 st overhead code block and the alignment mark code block. Secondly, the resources are wasted, and a large number of variables and logic processing units need to be added to the overhead code block locking module. The above-described problems also exist for the forwarding device P.

(2) The forwarding device P has repetitive operations in the process of descrambling and scrambling, resulting in high time delay.

As can be seen from fig. 4, when receiving the data code block D, the forwarding device P first performs a descrambling operation to form a data code block D', and performs a scrambling operation when transmitting data to restore the data code block D. It is easy to find that this descrambling and scrambling operation is redundant and brings about two negative effects as well: firstly, the time delay is increased, and secondly, the resource is wasted.

In view of the foregoing, it should be noted that the steps illustrated in the flowchart of the accompanying figures may be performed in a computer system such as a set of computer-executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than presented herein.

Fig. 9 is a flowchart of a data processing method according to an embodiment of the present invention, as shown in fig. 9, the method including the steps of:

step S902, determining a first time slot and a first data transmission channel corresponding to the first time slot based on the first bandwidth.

Optionally, before step S902, data to be transmitted needs to be acquired, and a target data code block corresponding to the data to be transmitted and a first bandwidth corresponding to the target data code block are determined. The first bandwidth corresponding to the target data code block may be determined to be obtained according to the type of data to be transmitted. For example, when the first bandwidth is determined to be 40GB, 8 unoccupied standard slots are selected from the 20 standard slots as the first slot corresponding to the target data code block, and the data transmission channel corresponding to the selected 8 unoccupied standard slots is used as the first data transmission channel corresponding to the target data code block. The target data code block is a data code block in the form of binary bits, which may be, but is not limited to, a 66B data code block, where the first two bits are alignment identification bits corresponding to the data code block, and the last 64 bits correspond to data to be transmitted.

Step S904, transmitting a second number of target data code blocks to a forwarding device based on the first data transmission channel, where a first transmission packet corresponding to the second number of target data code blocks includes: the first alignment mark and the first overhead code blocks of the first number have fixed intervals, and the first overhead code blocks of the first number are used for storing configuration information corresponding to the first time slots.

Optionally, the specific transmission form of the target data code block and the corresponding first transmission packet in step S904 may be: and sequentially transmitting the first alignment mark, the first overhead code blocks of the first number, and the target data code blocks of the second number to the forwarding device based on the first data transmission channel. And after the transmission of the last target data code block of the second number of target data code blocks is completed, completing the transmission of a group of complete flexible ethernet control information and the second number of target data code blocks. And at this time, the operation of sequentially transmitting the first alignment mark, the first overhead code blocks of the first quantity and the target data code blocks of the second quantity is executed again, and the operation is repeated in a circulating way until all the data code blocks corresponding to the band transfer data are completely transmitted. The first overhead code blocks of the first number are used to store configuration information corresponding to the first time slot, that is, the first overhead code blocks of the first number may carry a group of complete flexible ethernet control information.

It should be noted that, when there are a plurality of first data transmission channels corresponding to data to be transmitted, there may be a difference between the data transmission speed and the data transmission sequence of each data transmission channel, which causes a sequence deviation of the data received by the receiving device or the forwarding device. Therefore, an alignment mark (i.e. the above-mentioned first alignment mark) is inserted into the first transmission message corresponding to the data code block, and is used for performing consistency synchronization on the target data code blocks in the plurality of first data transmission channels, so as to ensure consistency of data transmission. The specific insertion format ensures that the interval between the target first pair Ji Biaoshi and the first number of first overhead code blocks is fixed, for example, the first overhead code blocks are fixedly inserted in the next clock cycle of the first alignment mark. Specific insertion mechanisms may be, but are not limited to: inserting a first alignment mark at intervals of a preset number of code blocks (data code blocks or overhead code blocks); the insertion mechanism of the first overhead code block may be, but is not limited to: the code blocks with the preset number are inserted into a first overhead code block with a first number which is continuous, the first overhead code block insertion position is adjacent to the first alignment mark and is positioned in the next clock period of the first alignment mark. Taking the example that the physical transmission channel with the bandwidth of 100GE is divided into 20 standard time slots, the insertion mechanism of the first alignment mark may be, but is not limited to, inserting a first alignment mark for code blocks (data code blocks or overhead code blocks) spaced by 16383 times 66B; the first number may be, but is not limited to, 20, and the insertion mechanism of the first overhead code block may be, but is not limited to: the code blocks (data code blocks or first alignment marks) spaced 16383 by 66B are inserted into 20 consecutive first overhead code blocks. The first overhead code block is inserted in a next clock cycle of the first alignment mark. A specific data transmission form is shown in fig. 10.

It should be noted that in the embodiment of the present invention, the overhead code blocks are inserted in the next clock cycle of the insertion of the alignment mark, since the alignment marks of 20 PCS data channels are 16383 66B code blocks apart. Therefore, the insertion interval of the overhead code blocks is also improved to 16383 66B (for example, with PHY of 100GE and 5G bandwidth granularity), and 256 complete overhead code blocks are optimized to 20 code blocks, and complete control information is improved to be sent at one time. The advantages are that: firstly, an alignment mark and an overhead code block can be simultaneously inserted at a sending end, two processing modules (an overhead insertion module and an alignment mark insertion module) are not needed to be respectively used in a traditional flexible Ethernet mechanism, and two processing links which are not related to each other are adopted for inserting the alignment mark and the overhead code block. Secondly, when the receiving end locks the alignment mark, the overhead code block is also locked. Thereby saving the time delay caused by the processing of overhead code blocks by the receiving end.

It is understood that the execution subject of the above steps S902 to S910 is a transmitting device. The ethernet based on IEEE802.3 can be applied to a physical transmission channel with a bandwidth of 100GE, and the physical transmission channel with a bandwidth of 100GE is divided into 20 standard time slots, and a bandwidth corresponding to each time slot is 5GB, that is, a bandwidth of a data transmission channel corresponding to each time slot is 5GB. Through the steps S902 to S910, the purpose of inserting the overhead code block and the alignment identifier in association can be achieved, so that the technical effects of simplifying the processing flow, improving the data transmission efficiency and reducing the time delay and the overhead complexity are achieved, and the technical problems of low alignment efficiency and excessive overhead and high time delay caused by the fact that the overhead code block and the alignment identifier are not associated and need time-sharing calibration in the related art are solved.

In an optional embodiment, before the transmitting a second number of target data code blocks to a forwarding device based on the first data transmission channel, the method further includes: acquiring data to be transmitted; coding the data to be transmitted to obtain a first data code block; and disturbing the first data code block to obtain the target data code block, wherein descrambling corresponding to the disturbing is performed by a receiving device.

It should be noted that, in the related art, the encoding processing and scrambling (i.e. perturbation processing) steps of the data to be transmitted are not continuously performed, and as shown in fig. 2, the insertion process of the overhead code block and the alignment mark in the transmitting device is not continuously performed, and the scrambling processing process is located between the insertion process of the overhead code block and the insertion process of the alignment mark. Different from the prior art, the scrambling processing process is advanced, after the first data code block is obtained through the coding processing of the data to be transmitted, the scrambling processing is directly carried out on the first data code block to obtain the target data code block, and on the basis, the first alignment mark and the related insertion of the first overhead code block are carried out on the obtained target data code block. The data processing flow of the sending device after adjustment is shown in fig. 11, which is equivalent to moving up the scrambling module in the sending device of fig. 2 between the flexible ethernet Calendar module (i.e., the FlexE Calendar module) and the encoding module. Through the adjustment of the processes, the data processing result of the sending equipment is not influenced, but the scrambling processing and descrambling processing flows of the data code block in the forwarding equipment are omitted in the subsequent data processing process, so that the data processing time is shortened, and the data processing efficiency of the forwarding equipment is improved.

According to an embodiment of the present invention, there is provided another data processing method, including:

step S911, a second number of target data code blocks are acquired.

Optionally, the first transmission packet corresponding to the second number of target data code blocks includes: the first alignment mark and the first overhead code blocks of the first number have fixed intervals, and the first overhead code blocks of the first number are used for storing configuration information corresponding to the first time slots.

Step S912, processes the target data code block to obtain a second data code block.

In an optional embodiment, the processing the target data code block to obtain a second data code block includes: acquiring the first alignment mark corresponding to the target data code block and the first overhead code blocks of the first number; and performing alignment processing on the target data code block based on the first alignment mark and the first overhead code blocks of the first number to obtain the second data code block.

Optionally, the aligning, performed on the target data code block based on the first alignment mark and the first number of first overhead code blocks to obtain the second data code block, includes: and performing alignment processing on the target data code block to obtain a third data code block, and performing reduction processing on the third data code block to remove related time slot information to obtain the second data code block.

It should be noted that, when there are a plurality of first data transmission channels corresponding to the target data code block, there may be a difference between the data transmission speed and the data transmission order of each data transmission channel, which causes a deviation in the order of the data received by the forwarding device. Therefore, after the forwarding device acquires the target data code blocks, the target data code blocks are aligned based on the first alignment marks and the first overhead code blocks of the first number, so that consistency synchronization of the target data code blocks from the plurality of first data transmission channels is guaranteed, and consistency of data transmission is guaranteed.

Optionally, fig. 12 is a schematic diagram of a data processing flow of an optional forwarding device according to an embodiment of the present invention, and as shown in fig. 12, in the embodiment of the present invention, compared with the data processing flow of the forwarding device in the prior art shown in fig. 4, the associated transmission of the second pair of Ji Biaoshi and the second overhead code block is implemented, and meanwhile, scrambling processing and descrambling processing flows of the data code block inside are omitted, so that the effects of reducing data processing time and improving data processing efficiency of the forwarding device are achieved.

Step S913, determining a second time slot and a second data transmission channel corresponding to the second time slot based on the second bandwidth.

It is to be understood that the second bandwidth is a transmission bandwidth corresponding to the second data code block. The second bandwidth corresponding to the second data code block may be the same as or different from the first bandwidth corresponding to the target data code block. For example, when it is determined that the second bandwidth is the same as the first bandwidth and 40GB, 8 unoccupied standard slots are selected from the 20 standard slots as the second slots corresponding to the second data code block, and the data transmission channels corresponding to the selected 8 unoccupied standard slots are used as the second data transmission channels corresponding to the second data code block.

Step S914, based on the second data transmission channel, transmits a second number of second data code blocks to the receiving device, where a second transmission packet corresponding to the second number of second data code blocks includes: a second pair Ji Biaoshi, a first number of second overhead code blocks, where the second alignment mark is fixed to an interval between the first number of second overhead code blocks, and the first number of second overhead code blocks are used to store configuration information corresponding to the second timeslot.

Optionally, the second transmission packet includes: a second pair Ji Biaoshi, a first number of second overhead code blocks, the second alignment mark and the first number of second overhead code blocks having a fixed interval therebetween, for example, the second overhead code blocks are fixedly inserted into a next clock cycle of the second alignment mark. The first number of overhead code blocks is used to store configuration information corresponding to the second timeslot, that is, the first number of overhead code blocks may carry a group of complete flexible ethernet control information. The insertion mechanism and the insertion process of the second alignment mark and the second overhead code block are the same as those of the first alignment mark and the first overhead code block, and are not described herein again.

It is understood that the execution subjects of the above steps S911 to S915 are forwarding devices. The ethernet based on IEEE802.3 can be applied to a physical transmission channel with a bandwidth of 100GE, and the physical transmission channel with a bandwidth of 100GE is divided into 20 standard time slots, and a bandwidth corresponding to each time slot is 5GB, that is, a bandwidth of a data transmission channel corresponding to each time slot is 5GB. Through the steps S911 to S915, the purpose of associating and locking the overhead code block and the alignment mark and further simultaneously checking the overhead code block and the alignment mark can be achieved, so that the technical effects of simplifying the processing flow, improving the data transmission efficiency and reducing the time delay and the overhead complexity are achieved, and the technical problems of low alignment efficiency and overlarge overhead caused by the fact that the overhead code block and the alignment mark are not associated and need time-sharing checking in the related technology are solved.

in step S921, a second number of second data code blocks are obtained.

Optionally, the second data code block is transmitted based on a second data transmission channel, where a second transmission packet corresponding to the second data code blocks in the second number includes: a second pair Ji Biaoshi, a first number of second overhead code blocks, where the second alignment mark has a fixed interval with the first number of second overhead code blocks, and the first number of second overhead code blocks are used to store configuration information corresponding to a second timeslot.

And step S922, obtaining the restored data to be transmitted based on the second data code block.

In an optional embodiment, the obtaining the reduced data to be transmitted based on the second data code block includes: acquiring the second alignment mark corresponding to the second data code block and the first number of second overhead code blocks; aligning the second data code blocks based on the second alignment marks and the first number of second overhead code blocks to obtain fourth data code blocks; performing descrambling processing on the fourth data code block to obtain a sixth data code block, wherein the scrambling processing corresponding to the descrambling processing is performed through sending equipment; and decoding the sixth data code block to obtain the restored data to be transmitted.

It should be noted that, in the case that there are a plurality of second data transmission channels corresponding to the second data code block, there may be a difference between the data transmission speed and the data transmission order of each data transmission channel, which results in a deviation of the order of the data received by the receiving device. Therefore, after receiving the second data code blocks, the receiving device performs alignment processing on the second data code blocks based on the second pairs Ji Biaoshi and the first number of second overhead code blocks, so as to ensure consistency synchronization on the second data code blocks from the plurality of second data transmission channels and ensure consistency of data transmission.

Corresponding to moving up the descrambling module in the receiving device of fig. 3 between the FlexE callback module and the decoding module. Through the adjustment of the above process, the data processing result of the receiving device is not affected, but the internal disturbance processing and descrambling processing flow of the data code block in the subsequent data processing process of the forwarding device is omitted, so that the data processing time is reduced, and the data processing efficiency of the forwarding device is improved.

Through the steps S921 to S922, the overhead code block and the alignment identifier can be locked in association, and then the overhead code block and the alignment identifier can be simultaneously corrected, so that the technical effects of simplifying the processing flow, improving the data transmission efficiency, and reducing the time delay and the overhead complexity are achieved, and the technical problems of low alignment efficiency and excessive overhead caused by time-sharing correction due to the fact that the overhead code block and the alignment identifier are not associated in the related art are solved.

step S932, the sending device transmits a second number of target data code blocks to a forwarding device based on the first data transmission channel, where a first transmission packet corresponding to the second number of target data code blocks includes: the first alignment mark and the first overhead code blocks of the first number have a fixed interval therebetween, and the first overhead code blocks of the first number are used for storing configuration information corresponding to the first time slots;

step S933, the forwarding device processes the target data code block to obtain a second data code block; determining a second time slot and a second data transmission channel corresponding to the second time slot based on a second bandwidth;

step S934, the forwarding device transmits a second number of second data code blocks to the receiving device based on the second data transmission channel, where a second transmission packet corresponding to the second number of second data code blocks includes: a second pair Ji Biaoshi, a first number of second overhead code blocks, where an interval between the second alignment mark and the first number of second overhead code blocks is fixed, and the first number of second overhead code blocks are used to store configuration information corresponding to the second timeslot;

step S935, the receiving device acquires a second number of second data code blocks; and obtaining the restored data to be transmitted based on the second data code block.

It is to be understood that the execution subject of the above steps S931 to S932 is a sending device, the execution subject of the above steps S933 to S934 is a forwarding device, and the execution subject of the above step S935 is a receiving device. The sending device, the forwarding device and the receiving device may be, but not limited to, a router device, a terminal device, etc. Through the steps, the purposes of inserting and locking the overhead code block and the alignment mark in an associated mode can be achieved, the technical effects of simplifying the processing flow, improving the data transmission efficiency and reducing the time delay and the overhead complexity are achieved, and the technical problems that in the related technology, the overhead code block and the alignment mark are not associated, time-sharing insertion and correction are needed, the alignment efficiency is low, and the overhead is too large are solved.

As shown in fig. 11 to 13, the data processing method specifically includes:

the sending device PE1 obtains data to be transmitted through a media access control sending module (i.e., MAC sending module). In a flexible Ethernet processing module (namely a Flexe module), a coding module is adopted to code the data to be transmitted to obtain a first data code block; and disturbing the first data code block by adopting a scrambling module to obtain the target data code block. In the Physical Coding Sublayer module (i.e., PCS module, physical Coding Sublayer). And sequentially inserting a first alignment mark and a first number of continuous first overhead code blocks for the target data code block by adopting an alignment mark and an overhead insertion module. And sending the target data code block, the first alignment mark and the first overhead code blocks of the first number to a forwarding device through a Physical medium adaptation layer (namely a PMA module) according to a first preset transmission mode.

The forwarding device P receives the target data code block from the sending device sequentially through the receiving module and the physical medium adaptation layer (i.e. the PMA module). In a physical coding sublayer module (namely a PCS module), a target data code block is subjected to block synchronization processing through a block synchronization module to obtain a synchronized target data code block; and the physical layer PHY channel alignment module aligns the synchronized target data code blocks to obtain a third data code block. And adopting a Flexe Calendar module to perform reduction processing on the third data code block to obtain a second data code block. And sequentially inserting a second pair Ji Biaoshi and a first number of continuous second overhead code blocks for the second data code block by adopting an alignment identifier and an overhead insertion module. And sending the target data code block, the second pair Ji Biaoshi and the first number of second overhead code blocks to a receiving device through a physical medium adaptation layer (namely, a PMA module) according to a second preset transmission mode.

After receiving the second data code block from the forwarding device through the receiving module and the physical medium adaptation layer (i.e., PMA module), the receiving device receives the target data code block from the transmitting device through the receiving module and the physical medium adaptation layer (i.e., PMA module). In the physical coding sublayer module (namely PCS module), the second data code block is subjected to block synchronization processing through a block synchronization module to obtain a synchronized second data code block; and the physical layer PHY channel alignment module aligns the synchronized second data code block to obtain a fourth data code block. In a flexible Ethernet module (namely a Flexe module), a flexible Ethernet Calendar module (namely a Flexe Calendar module) is adopted to carry out reduction processing on the fourth data code block to obtain a fifth data code block; descrambling module is adopted to perform descrambling processing to the fifth data code block to obtain a sixth data code block; and decoding the sixth data code block by using a decoding module to obtain the restored data to be transmitted, transmitting the restored data to be transmitted to a media access control receiving module (namely an MAC receiving module), and finishing the whole data transmission process.

It should be noted that, the embodiments of the present invention mainly solve the following two problems: the method comprises the steps that firstly, an associated overhead insertion module and an alignment mark insertion module are used for reducing the processing time delay of sending and receiving; and secondly, the scrambling module and the descrambling module are moved upwards, and the flexible Ethernet Flexe module of the 1.5 layer is further sunk, so that the data forwarding delay is reduced.

Compared with the prior art, the embodiment of the invention moves the scrambling module of the sending equipment between the Flexe Call terminal module and the coding module, and moves the descrambling module of the receiving equipment between the Flexe Call terminal module and the decoding module, thus the movement has no influence on the time delay of the sending equipment and the receiving equipment. However, for the forwarding device between the sending device and the receiving device, a scrambling module and a descrambling module for data code blocks in the forwarding device can be omitted, so that the data processing time is reduced, and the data processing efficiency of the forwarding device is improved. Compared with the prior art, the receiving and sending processes of the forwarding device P omit scrambling and descrambling operations, however, the data code block received by the receiving device is D, the data code block received in the sending module is still D, and the data code block does not bring influence, so that the time delay is reduced.

Also, in the embodiment of the present invention, the overhead code blocks are all inserted in the next clock cycle of the insertion of the alignment mark, since the alignment marks of 20 PCS data channels are 16383 66B code blocks apart. Therefore, the insertion interval of the overhead code blocks is also improved to 16383 (for example, with PHY of 100GE and 5G bandwidth granularity), and 256 complete overhead code blocks are optimized to 20 code blocks, and complete control information is improved to be sent at one time. The advantages are that: firstly, an alignment mark and an overhead code block can be simultaneously inserted at a sending end, two processing modules (an overhead insertion module and an alignment mark insertion module) are not needed to be respectively used in a traditional flexible Ethernet mechanism, and two processing links which are not related to each other are adopted to insert the alignment mark and the overhead code block. Secondly, when the receiving end locks the alignment mark, the overhead code block is also locked. Thereby saving the time delay brought by the processing of overhead code blocks by the receiving end.
