Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a method, device and equipment for transmitting information through a slice channel. Background Art

[0002] With the development of 5G and the increase in users across vertical industries, the demand for network slicing is increasing. The industry has made significant progress in exploring Ethernet-based slicing isolation technologies. For example, FlexE technology provides a slicing mechanism based on Ethernet physical interfaces, offering effective interface-level isolation. However, FlexE is currently limited to an interface-level technology and cannot meet the networking requirements of carrier networks. The Metropolitan Transport Network (MTN) is a new transport network technology system defined by the ITU-T for new services such as 5G. It effectively integrates TDM (time division multiplexing) and packet switching and consists of a metropolitan transport network segment layer and a metropolitan transport network path layer. The metropolitan transport network segment layer reuses FlexE logic, supports port binding, and is compatible with the Ethernet underlying protocol stack and standard Ethernet optical modules. The metropolitan transport network path layer supports TDM switching based on 66B code blocks, features comprehensive end-to-end Operation and Administration (OAM) mechanisms, and supports cross-multiplexing of any Nx5G channelized client signals.

[0003] However, currently both FlexE and MTN technologies only support channel division and slicing with a minimum granularity of 5Gbps at the Section layer. MTN reuses the FlexE frame format at the Section layer. The basic data unit frame format of the section layer is shown in Figure 1 and Figure 2 As shown, it consists of one 64B / 66B overhead block plus 20,460 64B / 66B payload blocks. For the MTN segment layer based on a 100Gbps example, the payload consists of 20 × 1023 blocks, while for the MTN segment layer based on a 50Gbps example, the payload consists of 10 × 1023 × 2 blocks. For a 100Gbps interface example, the minimum granularity is 5Gbps, divided into 20 time slot cycles. If a client occupies multiple time slots, the client's slice bandwidth can reach an integer multiple of 5Gbps, such as 10Gbps, 15Gbps, and so on.

[0004] Slicing provides TDM-based hard isolation capabilities. The transport network for integrated services will cover tens of millions of industries, and many new industries will also require network slicing for isolation. With the development of globalization, informatization, and cloud computing, the demand for dedicated lines will continue to increase. Dedicated lines with bandwidths exceeding 100 Mbps are growing rapidly, while bandwidth requirements for dedicated lines below 50 Mbps will persist for a long time. Currently, both FlexE and MTN technologies only support channel segmentation and slicing at the section layer with a minimum granularity of 5 Gbps. For dedicated line users with service bandwidths far less than 5 Gbps, using 5 Gbps FlexE or MTN slice channels will result in significant bandwidth waste and rapid network bandwidth exhaustion. If these dedicated line users are placed on the same 5 Gbps slice channel with other users through packet statistical multiplexing, the slice channel capabilities of deterministic low latency and hard pipe isolation for individual users cannot be met. The key challenge is to provide TDM slice channels with a bandwidth granularity of less than 5 Gbps within the existing FlexE or MTN basic frame formats. Summary of the Invention

[0043] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0044] like Figure 3 As shown, an embodiment of the present invention further provides a method for transmitting information of a slice channel, the method comprising:

[0045] Step 31: Divide the code blocks of the slice channel into at least one group of sub-time slots, each group of sub-time slots including N sub-time slot units;

[0046] In step 32, the signal to be transmitted through the slice channel is transmitted through at least M sub-time slot units among the N sub-time slot units, where N and M are both positive integers, and M is less than or equal to N.

[0047] In one possible implementation, the at least one group of sub-timeslots is cyclically grouped. For example, for a 100Gbps interface on FlexE or MTN, a slice channel is divided into 20 code block time slot cycles, resulting in a minimum granularity of 5Gbps. For a 50Gbps interface, the time slots are divided into 10 code block time slot cycles.

[0048] like Figure 4 As shown, for the code block time slot corresponding to each slice channel, the content in the channel is circulated using sub-time slot units, and each sub-time slot unit is circulated in number N. Each sub-time slot unit can be used to carry different slice channel clients with smaller bandwidth granularity.

[0049] In an optional embodiment, N is less than or equal to P1 / Q, where P1 is the transmission rate of the slice channel and Q is the slice granularity transmission rate of the slice channel. Here, the slice granularity transmission rate Q may be the minimum slice granularity transmission rate.

[0050] Here, N can be determined based on the minimum slice granularity to be achieved. For example, in a 5 Gbps channel, the minimum slice granularity is expected to be 10 Mbps. Then 5 Gbps divided by 10 Mbps is 500. Considering the overhead and idle resource usage, N can be set to 480, that is, the cycle is performed with 480 sub-time slot basic units.

[0051] like Figure 4 As shown, for a certain customer signal, the sub-time slot unit occupied by the customer signal is numbered m. Then, the customer signal can be periodically placed in a sub-slot unit numbered m with 480 sub-time slot units as a cycle. After 480 sub-time slot units, it is placed in the next sub-slot unit numbered m. Other customer signals that are not allocated the sub-slot unit numbered m cannot be placed in the sub-slot unit numbered m and can only be placed in sub-slot units with other numbers according to allocation.

[0052] In an optional embodiment of the present invention, the sub-timeslot unit includes: a start code block, an end code block, and a payload code block located between the start code block and the end code block.

[0053] Optionally, the sub-timeslot unit further includes: an overhead code block (OH) located between the start code block and the payload code block.

[0054] For each sub-time slot unit, use Figure 5 The sub-time slot unit starts with an S code block (e.g., 66 bits in length) and ends with a T code block (e.g., 66 bits in length).

[0055] Among them, the format of the S code block is as follows Figure 6 The format of the T code block is as shown. Figure 7 As shown (the T code block can use one of T0 to T7, preferably T7, so that data can be placed in the subsequent bit positions to improve bandwidth utilization). The advantage of using S code blocks and T code blocks as sub-timeslot units is that they are compatible with FlexE or MTN. For devices that do not process sub-timeslot units, S and T code blocks will be used as the start and end of the data. Therefore, these devices will recognize the sub-timeslot basic unit as ordinary data without generating errors.

[0056] For each sub-timeslot unit, an overhead (OH) is included between the S and T code blocks. The overhead can be used to indicate the channel number of the sub-timeslot basic unit, etc. The overhead can also carry other information, such as indicating the customer type and indicating OAM information.

[0057] In addition to the necessary S and T code blocks, and OH information, the remaining bits of the entire sub-timeslot unit can be used to carry client signals (Payload part).

[0058] In an optional embodiment of the present invention, each of the N sub-timeslot units has the same length. The sub-timeslot units have a fixed, consistent length. For example, assuming a sub-timeslot unit is 128 bytes long, S (66 bits) occupies 8 bytes, T (66 bits) occupies 8 bytes, and assuming OAM is 16 bytes, the remaining payload length is 96 bytes.

[0059] In an optional embodiment of the present invention, the payload code block is used for a data stream of an encoded signal that needs to be transmitted through a slice channel.

[0060] In this embodiment, in order to prevent the OAM, control code blocks, idle code blocks and other code blocks originally carried in the user data stream placed in the sub-timeslot unit from being identified and processed by the FlexE / MTN channel (if this will cause the sub-timeslot basic unit length, data, etc. to be changed), it is necessary to perform 64 / 66b encoding on the user data stream placed in the sub-timeslot unit, that is, the 66b code block of the user data stream enters the 64 bits of the payload 66b code block in the sub-timeslot unit as data. The first two bits of the payload 66b code block in the sub-timeslot unit are 01 (indicating that it is a data code block (D code block), see Figure 8 The part indicated by 01.

[0061] In an optional embodiment of the present invention, when sending a signal through the slice channel, there is at least one idle code block between two adjacent sub-time slot units in the N sub-time slot units.

[0062] In this embodiment, Figure 9 As shown, in order to facilitate rate adjustment (addition and deletion of IDLE code blocks) of the FlexE / MTN slice channel where the sub-time slot unit is located, a certain amount of IDLE (idle) code blocks need to be set between the sub-time slot units. The intermediate nodes can add or delete these IDLE code blocks according to the requirements of rate adjustment.

[0063] In an optional embodiment of the present invention, a signal that needs to be transmitted through a slice channel is transmitted through at least M sub-timeslot units among the N sub-timeslot units, including:

[0064] Among the N sub-time slot units, M continuous or discontinuous sub-time slot units are allocated, and the signal that needs to be transmitted through the slice channel is transmitted through the M sub-time slot units.

[0065] Optionally, the Among them, P2 is the transmission rate of the signal that needs to be transmitted through the slice channel, and Q is the slice granularity transmission rate of the slice channel.

[0066] In one achievable example, based on the customer's required slice bandwidth, multiple sub-timeslot unit numbers can be used for the same user data. For example, assuming a 5 Gbps channel with a desired minimum slice size of 10 Mbps, and 480 sub-timeslot units, a customer requiring 50 Mbps can be allocated 5 sub-timeslot units numbered 50 Mbps / 510 Mbps, as the minimum slice size is 10 Mbps. These numbers can be consecutive or discontinuous, for example, five sub-timeslot units numbered 1, 5, 15, 28, and 30. The customer's signal occupies these sub-timeslot units for transmission, thereby achieving the required 50 Mbps bandwidth.

[0067] The method described in the above embodiment of the present invention can transmit signals according to the N sub-timeslot units in each group of sub-timeslots in the code block of the slice channel; when receiving signals, the corresponding signal can be read from the N sub-timeslot units in each group of sub-timeslots. This method of the present invention can provide a TDM slice channel solution with a smaller bandwidth granularity of less than 5Gbps based on the existing FlexE or MTN basic frame format, thereby meeting the slicing and isolation requirements of vertical industry users with smaller bandwidth and enterprise dedicated lines.

[0068] An embodiment of the present invention further provides an information transmission device for a slice channel, comprising:

[0075] Optionally, the payload code block is used to transmit an encoded data stream of a signal that needs to be transmitted through a slice channel.

[0077] Optionally, the length of each sub-time slot unit in the N sub-time slot units is the same.
