In order to meet the requirement of the China Mobile 5G network, 5G transmission is based on a Slice Packet Network (SPN) mechanism. The SPN equipment adopts a slice forwarding mechanism, data is forwarded on the basis of 64/66 bits in a physical coding sublayer PCS, time slots are distributed to all sending channels, and the data is sent according to the time slots bound by the sending channels.

And transmitting data on the PCS layer of the NNI according to the time slot of the transmission channel corresponding to the service.

Therefore, the time slot granularity of 5G is large for many current services, and many current dedicated services are fast ethernet FE, gigabit ethernet GE, and the like, and only the granularity of 5G cannot be well adapted to these services, which results in serious bandwidth waste.

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
The invention provides a data transmission method aiming at the problem of bandwidth waste caused by inappropriate allocation of transmission time slots and services in the existing SPN transmission, and provides high-efficiency low-order time slot slice transmission service for clients through low-order time slots, thereby improving the SPN bandwidth transmission efficiency and meeting the requirements of more service types.
As shown in fig. 1, a data transmission method according to an embodiment of the present invention is applied to an SPN device in a sliced packet network, and includes:
In this embodiment, for data to be transmitted of a service in the SE channel, a corresponding time slot is divided into N sub-time slots according to the time slot quantization granularity value N. After the service is accessed, according to the step 101, the data to be transmitted is transmitted to the receiving end through the target sub-slot in the SE channel, so as to provide efficient low-order slot slice transmission service for the client, improve the SPN bandwidth transmission efficiency, and meet the requirements of more service types.
It should be noted that, in this embodiment, the timeslot quantization granularity value N is a non-zero integer set by a default or a user in advance, and according to the timeslot quantization granularity value, all timeslots may be sub-slotted (i.e., each timeslot is a target timeslot), and further, sub-slotted for a timeslot of a specific service (i.e., the target timeslot is a specific timeslot).
For example, a 100G port may be divided into 20 slots, each slot being 5G, on the flexible ethernet FlexE interface shown in fig. 2. From the slot granularity value N, the low-order sub-slots divide each slot into N sub-slots. After the service is accessed, the service is allocated according to the sub-time slot, a single sub-time slot or a plurality of sub-time slots (M) correspond to one service, and the rate of each sub-time slot can be 5M/N (GE).
The receiving end is the SPN sub-device of the SPN device that sends the data to be transmitted, that is, the SPN device that receives the data to be transmitted.
In this embodiment, as shown in fig. 3, before step 101, the method further comprises:
102, receiving transmission configuration information sent by transmission control equipment;
and 103, configuring data transmission according to the transmission configuration information.
Here, the transmission control device may be a software defined network, SDN, controller that determines transmission configuration information for the SPN device associated with the service data application and sends the transmission configuration information to the associated SPN device. Therefore, after the transmission configuration information is received, the data transmission configuration can be carried out by the transmission configuration information, and after the configuration is completed, the data to be transmitted corresponding to the service data application is transmitted to the receiving end through the sub-time slots divided in the SE channel. The service data transmission application is a bandwidth application provided by the service system for the service requirement, and the transmission control device can specify the time slot required for transmission according to the service data transmission application.
Optionally, the transmission configuration information includes an identifier of the target timeslot and the timeslot quantization granularity value;
according to the transmission configuration information, configuring data transmission, including:
and dividing the target time slot into a plurality of sub time slots according to the identifier of the target time slot and the time slot quantization granularity value, and updating the channel time slot information of the target time slot.
Here, after receiving the transmission configuration information including the identifier of the target timeslot and the timeslot quantization granularity value, the SPN device may divide the target timeslot into a plurality of sub-timeslots according to the identifier of the target timeslot and the timeslot quantization granularity value, where the number of the sub-timeslots is the same as the timeslot quantization granularity value, so as to be used for data transmission, and may update its own channel timeslot information to record the low-order sub-timeslot information of the timeslot.
Additionally, in an embodiment of the present invention, before step 102, the method further comprises:
receiving channel time slot information sent by SPN parent equipment and SPN child equipment, and sending the channel time slot information to the SPN parent equipment and the SPN child equipment;
and sending the received channel time slot information and the channel time slot information of the channel time slot information to transmission control equipment.
Here, for the channel timeslot information in which the low-order sub-slotted information of the timeslot is recorded, after the SPN device collects the channel timeslot information sent by the SPN parent device and the SPN child device, the SPN device can send the channel timeslot information together with the channel timeslot information of the SPN parent device and the SPN child device to the transmission control device, so that the transmission control device can know the low-order sub-slotted state of the current SE channel through the channel timeslot information of each SPN device, and further determine to give transmission configuration information that can better apply to the service data transmission sub-timeslot. Of course, the SPN device will also send its own channel slot information to the SPN parent device and the SPN child device. Here, the SPN parent device is the last node device of the transmission, and the SPN child device is the next node device of the transmission.
In this embodiment, optionally, the channel timeslot information includes a sub-timeslot identification, a timeslot identification of a sub-timeslot, and a start position of the sub-timeslot.
Thus, whether subslot formation is supported or not can be known through the subslot formation identifier; the time slot identification of the sub-time slot can know the time slot which is divided into the sub-time slot specifically, and the definition of the sub-time slot of the local terminal and the opposite terminal is checked; the start position of the sub-slot defines which sub-slot starts to correspond to the data to ensure efficient reception of the data. For example, as shown in fig. 4, the starting position of the sub-slot is 3, that is, sub-slot 3 is the starting sub-slot of the corresponding data, the receiving end can extract the traffic data from sub-slot 3.
Specifically, the channel timeslot information is carried in a flexible ethernet header message.
In this way, the SPN device transmits data, and can carry channel time slot information through the flexible ethernet header message FlexE OH, and notify the SDN controller through the southbound interface, and the SDN controller allocates and manages the time slot used for service transmission according to the SE channel time slot information. The FlexE OH structure carrying channel slot information is shown in table 1 below:
TABLE 1
If the subslot identification in the channel timeslot information indicates that the SE channel of the SPN device does not support subslot, the received data is still sent in the random timeslot.
Further, to accommodate low order sub-slotted data transmission, prior to step 101, the method further comprises:
constructing a data sending queue corresponding to the target sub-time slot according to the data to be transmitted;
transmitting data to be transmitted to a receiving end through a target sub-time slot in a layered Ethernet channel, comprising:
and after reading the data from the data sending queue and filling the data into the target sub-time slot, sending the data to the receiving end.
According to the steps, before transmission, a data sending queue corresponding to a target sub-time slot is constructed by data to be transmitted aiming at the divided sub-time slots, then, in the transmission process, the data is read from the data sending queue and filled into the target sub-time slot, and then the data is sent to a receiving end, and data transmission based on the sub-time slot is completed. For example, as shown in fig. 2, queue 1 is a data transmission queue constructed for a first target sub-slot of data a to be transmitted, and queue 2 is a data transmission queue constructed for a second target sub-slot of data B to be transmitted.
It should also be appreciated that in this embodiment, optionally, the transmission configuration information further includes an identifier of a data receiving timeslot;
transmitting data to be transmitted to a receiving end through a target sub-time slot in a layered Ethernet channel, comprising:
after receiving data transmitted by a sub-time slot of a transmitting end, judging whether the identifier of the time slot to which the sub-time slot belongs is the same as the identifier of the data receiving time slot;
and if the data are the same, the received data are used as the data to be transmitted and are transmitted to the receiving end through the target sub time slot.
Thus, when the SPN device receiving the transmission configuration information forwards data, it may first determine the consistency of the time slots, that is, whether the identifier of the time slot to which the sub-time slot of the received data belongs is the same as the identifier of the data receiving time slot, and under the same condition, the validity of the data can be guaranteed, and the data is transmitted to the receiving end through the target sub-time slot. Certainly, for different situations, the SPN device may report an error, and retransmit the data after being corrected by the transmission control device or the SPN parent device.
In summary, the data transmission method according to the embodiment of the present invention transmits the data to be transmitted to the receiving end through the target sub-slot in the SE channel by sub-time slotting, so as to provide a high-efficiency low-order slot slice transmission service for the client, support richer bandwidth services, and improve the SPN bandwidth transmission efficiency.

Therefore, the SE channel subslot can be realized, high-efficiency low-order time slot slice transmission service is provided for clients, richer bandwidth services can be supported, and the SPN bandwidth transmission efficiency is improved.
Generally, after receiving a service data transmission application, a transmission control device determines channel time slot information, where the service data transmission application is a bandwidth application provided by a service system for a service requirement, and the transmission control device can specify a time slot, a sub-time slot, and the like required for transmission according to the service data transmission application.

Here, the SPN parent device is the last node device of the transmission and the SPN child device is the next node device of the transmission.
Optionally, the channel timeslot information includes a sub-slotted identifier, a timeslot identifier of a sub-timeslot, and a start position of the sub-timeslot.

The FlexE OH structure carrying channel slot information is shown in table 1 above and will not be described here.
Optionally, the transmission configuration information further includes an identifier of a data receiving slot.
After receiving the transmission configuration information including the identifier of the data receiving time slot, when the SPN device forwards the data, it may first determine the consistency of the time slots, that is, whether the identifier of the time slot to which the sub-time slot of the received data belongs is the same as the identifier of the data receiving time slot, and under the same condition, the validity of the data can be guaranteed, and the data is transmitted to the receiving end through the target sub-time slot as the data to be transmitted.
