[0031] It should also be understood that references to "one embodiment" or "some embodiments" in the description of the embodiments of the present application mean that one or more embodiments of the embodiments of the present application include specific features, structures, or characteristics described in conjunction with the embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in other embodiments," etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized.

[0032] The Flexible Ethernet (FlexE) protocol standard technical specification defines a method for delivering customer services at speeds of n (n is a positive integer) * 5G (in bits per second). FlexE physical interfaces can efficiently carry customer services at speeds above 5G. To address the need to carry customer services at speeds slower than 5G, communications network operators have defined technical requirements for fine-grained slicing of packet networks and proposed a fine-grained frame structure. The ITU, an international standards organization, has developed similar fine-grained frame structures. However, these fine-grained frames consist of an S-code block, several D-code blocks, and a T-code block. These fine-grained frame structures can only be carried and transmitted on FlexE or MTN interfaces (which also utilize FlexE technology). They cannot be carried directly on standard Ethernet interfaces, such as 10G Ethernet or 25G Ethernet, because these interfaces do not support FlexE technology and cannot create 5G-speed time slots similar to FlexE.

[0033] Based on this, the embodiments of the present application provide a service frame transmission method and system, a sending device, a receiving device, and a storage medium. Since the fine-grained bearer frame is carried and transmitted on the time slot of 5G speed, the embodiments of the present application interleave multiple groups of fine-grained bearer frames corresponding to multiple groups of customer services according to the transmission rate of different Ethernet interfaces and the multiple of 5G speed, and then transmit them through the Ethernet interface. That is, the corresponding fine-grained bearer frames are interleaved and transmitted for different Ethernet speeds, thereby realizing the transmission of fine-grained bearer frames on different Ethernet interfaces.

[0034] The service frame transmission method and system, sending device, receiving device, and storage medium provided in the embodiments of the present application are specifically explained through the following embodiments. First, the service frame transmission method in the embodiments of the present application is described.

[0035] An embodiment of the present application provides a service frame delivery method. Referring to Figure 1, Figure 1 is a flow chart of a service frame delivery method provided by an embodiment of the present application. The service frame delivery method can be applied to a service frame delivery device. As shown in Figure 1, the service frame delivery method provided by this embodiment includes steps S10 to S30.

[0036] Step S10 : determining the number of interleaving groups of fine-grained bearer frames based on the transmission rate of the target interface, wherein the fine-grained bearer frames correspond to the mapping of the customer services.

[0037] The service frame transmission method provided in this embodiment is applied to a service frame sending device, i.e., a sending end. In this embodiment, the transmission rate of the target interface is first compared with the 5G rate, and then the fine-grained bearer frames are grouped and then sent through the target interface, thereby realizing the transmission of fine-grained bearer frames on different Ethernet interfaces.

[0038] As an example, since the fine-grained bearer frame is carried and transmitted on the time slot of 5G speed, a total of 480 sub-time slots are divided in the fine-grained bearer frame. When the fine-grained bearer frame is carried on the time slot of 5G speed, the sub-time slot speed of each fine-grained bearer frame is 10M (excluding the bandwidth waste such as the overhead of the fine-grained bearer frame). The interface speed of 10G Ethernet and 25G Ethernet is an integer multiple of 5G speed. Two groups of fine-grained bearer frames can be carried on 10G Ethernet and five groups of fine-grained bearer frames can be carried on 25G Ethernet.

[0039] Step S20: interweave each group of the fine-grained bearer frames according to a preset standard to obtain an interleaved information flow, and send the interleaved information flow through the target interface.

[0040] In this embodiment, after the fine-grained bearer frames are grouped, each group of fine-grained bearer frames is interleaved according to a preset standard to obtain an interleaved information flow, and the interleaved information flow is sent through the target interface to complete the service frame sending process.

[0041] In some feasible embodiments, the step of interleaving each group of the fine-grained bearer frames according to a preset standard to obtain an interleaved information flow in the above-mentioned step S20 may include: step S21, interleaving each group of the fine-grained bearer frames according to the fine-grained bearer frame size as a frame interleaving unit to obtain a frame interleaved information flow.

[0042] In this embodiment, the preset standard is the fine-grained bearer frame size, and the interleaved information flow is frame interleaving information.

[0043] As an example, when the target interface is a 10G Ethernet interface, referring to Figure 2, at the transmitting end, two groups of customer services are respectively mapped to two groups of fine-grained bearer frames, and the speed of each group of fine-grained bearer frames is 5G. The two groups of fine-grained bearer frames are interleaved according to the fine-grained bearer frame size as the interleaving unit. After interleaving, a 10G fine-grained bearer frame flow is formed, which can then be sent out through the 10G Ethernet interface.

[0044] As an example, when the target interface is a 25G Ethernet interface, referring to Figure 3, at the sending end, five groups of customer services are respectively mapped to five groups of fine-grained bearer frames. The speed of each group of fine-grained bearer frames is 5G, and the five groups of fine-grained bearer frames are interleaved according to the fine-grained bearer frame size as the interleaving unit. After interleaving, a 25G fine-grained bearer frame flow is formed, which can then be sent out through the 25G Ethernet interface.

[0045] In some feasible embodiments, the step of interleaving each group of the fine-grained bearer frames according to a preset standard to obtain an interleaved information stream in the above-mentioned step S20 may also include: step S22, performing code block interleaving on each group of the fine-grained bearer frames according to the code block size as the code block interleaving unit to obtain a code block interleaved information stream.

[0046] In this embodiment, the preset standard is the code block size, and the interleaved information flow is the code block interleaving information. In addition to performing frame interleaving based on the fine-grained bearer frame size as the interleaving unit, interleaving can also be performed based on the code block size.

[0047] As an example, when the target interface is a 10G Ethernet interface, referring to Figure 4, at the transmitting end, two groups of customer services are respectively mapped to two groups of fine-grained bearer frames, and the speed of each group of fine-grained bearer frames is 5G. The two groups of fine-grained bearer frames are interleaved according to the interleaving unit of 66-bit code block size. After interleaving, a code block stream with a rate of 10G is formed, and the code block stream is sent out through the 10G Ethernet interface.

[0048] As an example, when the target interface is a 25G Ethernet interface, referring to Figure 5, at the transmitting end, five groups of customer services are respectively mapped to five groups of fine-grained bearer frames, and the speed of each group of fine-grained bearer frames is 5G. The five groups of fine-grained bearer frames are interleaved according to the interleaving unit of 66-bit code block size. After interleaving, a code block stream with a rate of 25G is formed, and the code block stream is sent out through the 25G Ethernet interface.

[0049] A similar method to the above example can also be used for Ethernet interfaces of other rates. As long as the Ethernet interface rate is a multiple of the 5G rate, if the multiple is n (n is a positive integer), n groups of fine-grained bearer frames are interleaved and then sent through the Ethernet interface.

[0050] In some feasible embodiments, before the step of sending the interleaved information stream through the target interface in the above step S20, the service frame delivery method may also include: setting a group number in each group of the fine-grained bearer frames; or inserting sequential code blocks between each group of the fine-grained bearer frames.

[0051] In order for the receiving end to locate the sequential relationship of each fine-grained bearer frame, the transmitting end needs to transmit positioning flag information or numbering information of each group. Therefore, before sending the interleaved information stream through the target interface, this embodiment can set a group number for each group of fine-grained bearer frames, or insert sequential code blocks between each group of the fine-grained bearer frames to achieve the purpose of transmitting positioning flag information or numbering information of each group.

[0052] Figure 6 shows the 802.3 protocol 64 / 66 encoding rules. Each code block consists of 66 bytes. The first two bits are the synchronization header. A synchronization header bit of "01" indicates a D code block (data code block). The following 8 bytes (64 bits) contain 8 bytes of data content. A synchronization header bit of "11" indicates a control code block. The first byte that follows indicates the control block type. The following 7 bytes contain the control block content, which is determined by the control block type. Both S code blocks and T code blocks are control code blocks. The first byte of an S code block is 0x78, indicating that the control code block is an S code block. In addition to indicating the end of the block, the T code block can also carry client byte content (located in the last 7 bytes of the code block). The Ethernet standard classifies T-blocks into eight types: T0, T1, T2, T3, T4, T5, T6, and T7. T0 (first byte is 0x87) carries no customer information, T1 (first byte is 0x99) carries one byte of customer information, T2 (first byte is 0x99) carries two bytes of customer information, and so on. T7 (first byte is 0x99) carries two bytes of customer information, and so on. During reception, the optical port identifies 66-bit blocks from the received data stream, recovers the original 64-bit data from the 66-bit blocks, and reassembles the data packet. For 100G services, every 20 66-bit data blocks form a data block group. Each group contains 20 data blocks, representing 20 time slots, each of which represents a 5G (bit / s) bandwidth service speed.

[0053] As an example, Figure 6 defines multiple code block types, some of which can be used as special code blocks to function as location marker information. For example, one of the code blocks is an O code block, used to transmit fault information. The format of the O code block is shown in the O block structure in Figure 7. The code block consists of a "10" field, a 0x4B field, a D1 field, a D2 field, a D3 field, an O0 field, and an all-zero field. The O0 field indicates the O code block type. Currently, the four values ​​"1," "2," "C," and "F" are enabled; other values ​​are reserved. "C" is currently only used for FlexE or MTN interfaces and is not used in ordinary Ethernet interfaces. When the O0 field contains a defined value, the D1, D2, and D3 fields indicate the transmitted content. In this embodiment, the O0 field can be set to other values, such as "A," or the value "C" (which is not used in ordinary Ethernet interfaces), indicating that the O code block is a specially defined code block in this embodiment for location positioning, as shown in Example 1 of the O block application structure in Figure 7. In a specially defined O code block, one of the D1 field, D2 field, and D3 field may also be used to convey the group number of the fine-grained bearer frame, as shown in O block application structure example 2 in FIG7 .

[0054] As an example, in this embodiment, the principle of using a specially defined O code block as a positioning marker (i.e., inserting sequential code blocks between fine-grained bearer frames) is shown in Figure 8. At the transmitting end, the specially defined O code block is inserted during interleaving. When a frame is used as the interleaving unit, the specially defined O code block is inserted in the middle of the fine-grained bearer frame (the upper half of Figure 8). When a code block is used as the interleaving unit, the specially defined O code block is inserted in the middle of the code block (the lower half of Figure 8). Using a specially defined O code block as a positioning marker indicates which group of fine-grained bearer frames the subsequent adjacent fine-grained bearer frame or code block belongs to. For example, the fine-grained bearer frame following the specially defined O code block is the first group of fine-grained bearer frames, or the code block following the specially defined O code block is the code block of the first fine-grained bearer frame.

[0055] As an example, since a specially defined O code block needs to be defined and inserted when applying a positioning marker, in a specific implementation, an S code block can also be used to achieve positioning (i.e., setting a group number in a fine-grained bearer frame). Since fine-grained bearer frames are composed of S code blocks, several D code blocks, and T code blocks, and the S code block structure is shown in the S block structure in Figure 9, in the Ethernet standard, the first two bits of the S code block are "10", indicating that it is a control type code block, and the following content is "0x78", which is a control word, indicating that it is an S block. The 7 bytes following the control word content are fixed values, consisting of 6 bytes of "0x55" and 1 byte of "0xD5". The 7 bytes following the control word content are fixed values ​​and have no practical effect during transmission. They can replace the transmission number information to indicate the group number of the fine-grained bearer frame in which the S code block is located, as shown in the S block application structure in Figure 9.

[0056] In addition, in addition to the method provided in the above example of using specially defined code blocks as positioning marks and setting group numbers in S code blocks, overhead fields are also defined in fine-grained bearer frames, and the content of the overhead field can also be set to the group number field of the fine-grained bearer frame. As shown in Figure 10, the sender can also allocate a field definition number in the overhead field to convey the specific number of each fine-grained bearer frame.

[0057] This embodiment provides a service frame transmission method, which is applied to a service frame sending device. According to the relationship between the transmission rate of different Ethernet interfaces and the multiple of 5G speed, multiple groups of fine-grained bearer frames corresponding to multiple groups of customer services are interleaved and then sent through the Ethernet interface. That is, for different Ethernet speeds, the corresponding fine-grained bearer frames are interleaved and then sent, thereby realizing the sending of fine-grained bearer frames through different Ethernet interfaces.

[0058] In addition, another embodiment of the present application also provides a service frame delivery method. Referring to Figure 11, Figure 11 is a flow chart of a service frame delivery method provided by another embodiment of the present application. The service frame delivery method can be applied to a service frame delivery device. As shown in Figure 11, the service frame delivery method provided in this embodiment includes steps S10' to S30'.

[0059] Step S10 ′: receiving the interleaved information flow based on the target interface.

[0060] The service frame transmission method provided in this embodiment is applied to a service frame receiving device, that is, a receiving end. In this embodiment, the interleaved information flow from the sending end is received through a target interface and the interleaved information flow is further processed.

[0061] Step S20': deinterleave the interleaved information flow according to a preset standard to obtain a plurality of groups of fine-grained bearer frames, and demap each group of the fine-grained bearer frames to obtain corresponding customer services.

[0062] In this embodiment, after receiving the interleaved information stream, the interleaved information stream will be deinterleaved according to the preset standard to obtain several groups of fine-grained bearer frames, and then each group of customer services can be demapped from each group of fine-grained bearer frames to complete the service frame reception process.

[0063] As an example, the number of interleaving groups of fine-grained bearer frames is determined based on the 5G rate and the transmission rate of the target interface. If the target interface is a 10G Ethernet interface, the number of interleaving groups of fine-grained bearer frames is two. If the target interface is a 25G Ethernet interface, the number of interleaving groups of fine-grained bearer frames is five.

[0064] In some feasible embodiments, the step of deinterleaving the interleaved information stream according to a preset standard to obtain a plurality of groups of fine-grained bearer frames in step S20′ may include:

[0065] Step S21 ′: deinterleave the frame interleaved information stream according to the fine-grained bearer frame size to obtain a plurality of groups of fine-grained bearer frames.

[0066] In this embodiment, the preset standard is the fine-grained bearer frame size, and the interleaved information flow is frame interleaving information.

[0067] As an example, when the target interface is a 10G Ethernet interface, refer to Figure 12, which is the reverse process of Figure 2. At the receiving end, after receiving the frame interleaving information flow on the 10G Ethernet interface, the frame is deinterleaved according to the fine-grained bearer frame size as the interleaving unit. After deinterleaving, two groups of fine-grained bearer frames are obtained. The speed of each group of fine-grained bearer frames is 5G, and each group of customer services is obtained by demapping from each group of fine-grained bearer frames.

[0068] As an example, when the target interface is a 25G Ethernet interface, refer to Figure 13, which is the reverse process of Figure 3. At the receiving end, after receiving the frame interleaving information flow on the 25G Ethernet interface, the frame is deinterleaved according to the fine-grained bearer frame size as the interleaving unit. After deinterleaving, five groups of fine-grained bearer frames are obtained. The speed of each group of fine-grained bearer frames is 5G, and each group of customer services is obtained by demapping from each group of fine-grained bearer frames.

[0069] In some feasible embodiments, the above step S20′ deinterleaving the interleaved information flow according to a preset standard to obtain a plurality of groups of fine-grained bearer frames may further include:

[0070] Step S22 ′: deinterleave the code block interleaved information stream according to the code block size to obtain a plurality of groups of fine-grained bearer frames.

[0071] In this embodiment, the preset standard is the code block size, and the interleaved information stream is code block interleaved information. In addition to performing deinterleaving based on the fine-grained bearer frame size as the interleaving unit, deinterleaving can also be performed based on the code block size.

[0072] As an example, when the target interface is a 10G Ethernet interface, refer to Figure 14, which is the reverse process of Figure 4. At the receiving end, after receiving the code block on the 10G Ethernet interface, the code block is deinterleaved according to the code block size as a unit. After deinterleaving, two groups of code block streams are obtained, and each group of code block streams constitutes a fine-grained bearer frame. The speed of each group of fine-grained bearer frames is 5G, and each group of customer services is obtained by demapping from each group of fine-grained bearer frames.

[0073] As an example, when the target interface is a 25G Ethernet interface, refer to Figure 15, which is the reverse process of Figure 5. At the receiving end, after receiving the code block on the 25G Ethernet interface, the code block is deinterleaved according to the code block size as a unit. After deinterleaving, two groups of code block streams are obtained. Each group of code block streams constitutes a fine-grained bearer frame. The speed of each group of fine-grained bearer frames is 5G, and each group of customer services is obtained by demapping from each group of fine-grained bearer frames.

[0074] A similar method to the above example can also be used for Ethernet interfaces of other rates. As long as the Ethernet interface rate is a multiple of the 5G rate, if the multiple is n (n is a positive integer), the interleaved information flow is deinterleaved into n groups of fine-grained bearer frames to obtain fine-grained bearer frames, and then the fine-grained bearer frames are demapped to obtain the corresponding customer services.

[0075] In some feasible embodiments, before the above-mentioned step S20', the service frame delivery method may further include: determining the arrangement order of each group of fine-grained bearer frames according to the group number in each group of fine-grained bearer frames; or, determining the arrangement order of each group of fine-grained bearer frames according to the sequential code blocks between each group of fine-grained bearer frames.

[0076] In this embodiment, before demapping each fine-grained bearer frame, it is also necessary to parse the arrangement order of each group of fine-grained bearer frames, mainly based on the positioning flag information transmitted by the sending end or the group number of each group of fine-grained bearer frames. If the sending end sets the group number in the fine-grained bearer frame to realize the positioning function, the arrangement order of each group of fine-grained bearer frames is determined based on the group number; if the sending end inserts sequential code blocks between fine-grained bearer frames as positioning flag information, the arrangement order of each group of fine-grained bearer frames is determined based on the sequential code blocks.

[0077] As an example, referring to Figure 8, when the transmitting end uses a specially defined O code block as a positioning mark (that is, the transmitting end inserts sequential code blocks between fine-grained bearer frames), at the receiving end, it is necessary to find the specially defined O code block, and use the specially defined O code block as the positioning mark to determine the group number of subsequent fine-grained bearer frames or the group number of each group of fine-grained bearer frame code blocks, and then determine the group number of all fine-grained bearer frames based on the interleaving order.

[0078] As an example, referring to Figure 9, when the transmitting end uses the S code block to achieve positioning (that is, the transmitting end sets the group number in the fine-grained bearer frame), at the receiving end, the group number of the fine-grained bearer frame is carried by the S code block. After the interleaved information stream is deinterleaved, the specific number of each fine-grained bearer frame can be known according to the group number carried by the S code block, and then each group of fine-grained bearer frames can be distinguished.

[0079] In addition, in addition to the method provided in the above example of using specially defined code blocks as positioning marks and setting group numbers in S code blocks, an overhead field is also defined in the fine-grained bearer frame, and the content of the overhead field can also be set to the group number field of the fine-grained bearer frame. As shown in Figure 10, when the sending end divides a field definition number in the overhead field and transmits the specific number of each fine-grained bearer frame, the receiving end can also obtain the specific number of each fine-grained bearer frame based on the number carried by the overhead field.

[0080] This embodiment provides a service frame transmission method, which is applied to a service frame receiving device. After receiving the interleaved information stream through the Ethernet interface, the number of interleaved groups of fine-grained bearer frames contained in the interleaved information stream is determined according to the relationship between the transmission rate of different Ethernet interfaces and the multiple of the 5G speed. The interleaved information stream is deinterleaved to obtain multiple groups of fine-grained bearer frames. Each group of fine-grained bearer frames is demapped to obtain the corresponding customer service, thereby realizing the reception of fine-grained bearer frames through different Ethernet interfaces.

[0081] In addition, an embodiment of the present application also provides a service frame sending device, which is used to implement the service frame transmission method applied to the service frame sending device provided in any of the above embodiments.

[0082] The service frame sending device provided in this embodiment and the service frame transmission method provided in the above embodiment belong to the same inventive concept. The technical details not described in detail in this embodiment can be referred to any of the above embodiments, and this embodiment has the same beneficial effects as executing the service frame transmission method.

[0083] In addition, an embodiment of the present application also provides a service frame receiving device, which is used to implement the service frame transmission method applied to the service frame receiving device provided in any of the above embodiments.
