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 problems that in the existing SPN transmission, an SE channel can only be occupied by one client, and the occupation of time slots in the SE channel is occupied according to the allocated time slots during transmission, so that the bandwidth and the time slots are easy to idle.
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:
step 101, transmitting data to be transmitted to a receiving end through a fixed time slot in a layered ethernet channel, wherein the layered ethernet channel is a multi-service data transmission channel.
Through the steps, the data transmission method of the embodiment of the invention transmits the data to be transmitted through the fixed time slot in the SE channel, so that the corresponding service data (namely the data to be transmitted of the same service) is transmitted through the fixed time slot in the SE channel of the SPN device.
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. 2, before step 101, the method further comprises:
step 102, receiving transmission configuration information sent by a transmission control device after receiving a service data transmission application;
and 103, configuring data transmission according to the transmission configuration information.
Here, the transmission control device may be a software defined network SDN controller, and after receiving a service data application, the SDN controller may determine transmission configuration information for an SPN device related to the service data application, and send the transmission configuration information to the related 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 fixed time slot in the SE channel.
It should be noted that the service data transmission application is a bandwidth application provided by the service system for a service requirement, and the transmission control device may specify a time slot required for transmission according to the service data transmission application. However, in order to effectively utilize the free time slots in the SE channel, 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 transmission control equipment to the transmission control equipment.
The channel time slot information in the embodiment is used for indicating the use state of the current SE channel of the SPN device, and after collecting the channel time slot information sent by the SPN parent device and the SPN child device, the SPN device can send the channel time slot information together with the channel time slot information to the transmission control device, so that the transmission control device can know the use state of the current SE channel through the channel time slot information of each SPN device, and further determine to give transmission configuration information capable of better utilizing the idle time slot. 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, the transmission configuration information includes a transmission timeslot allocated to the service data transmission application;
step 103 comprises:
sending own channel time slot information to opposite terminal SPN equipment, and receiving the channel time slot information sent by the opposite terminal SPN equipment;
judging whether the time slots are aligned or not according to the channel time slot information;
and under the condition of time slot alignment, determining a fixed time slot for transmitting the data to be transmitted by the transmission time slot.
Through the steps, the SPN device can send its channel timeslot information to the opposite-end SPN device (the SPN device performing data transmission with the SPN device), and can also receive the channel timeslot information sent by the opposite-end SPN device, and then jointly determine whether the timeslots are aligned according to the channel timeslot information of itself and the opposite-end SPN device, so that the transmission timeslot allocated by the transmission control device determines the fixed timeslot for transmitting the data to be transmitted under the condition that the timeslots are aligned, so that the SPN device at the receiving end can effectively receive the data to be transmitted.
For example, for a bandwidth applied for service data transmission, the SDN controller first obtains a slot number corresponding to the bandwidth, and then determines a transmission slot allocated to the service according to the occupation and idle conditions of the received channel slot information by an SE channel slot, for example, informs the SPN device 2 (a next node device for SPN device 1 transmission) that the transmission slot of the SPN device 1 is a 3 rd to 5 th slot, and informs the SPN device 2 (a next node device for SPN device 1 transmission) to receive data on the transmission slot of the SPN device 1, that is, on the 3 rd to 5 th slot. In order to ensure the transmission effectiveness, whether the transmission time slots are aligned is judged according to the allocated transmission time slots. In the case of time slot alignment, the fixed time slot for transmitting the data to be transmitted can then be determined from the allocated transmission time slots. Thus, the SPN device 1 will transmit according to the time slot, and obtain the data to be transmitted from the transmit queue and fill the corresponding time slot 3-5, and then transmit to the physical coding sublayer PCS of the physical layer. After receiving the service data at the 3 rd to 5 th time slots of the SPN device 1, the SPN device 2 transmits the service data to the next node device at the 8 th to 10 th time slots of its SE channel (the transmission time slot allocated to the SPN device 2 by the SDN controller).
Certainly, in this embodiment, there is also a case that the timeslots are not aligned, so, after determining whether the timeslots are aligned according to the channel timeslot information, the method includes:
and under the condition that the time slots are not aligned, carrying out time slot calibration until the time slots are aligned.
Here, for the case where it is judged that the time slots are not aligned, time slot calibration is performed until the time slots are aligned. The time slot calibration is completed by negotiation of SPN equipment at two transmission ends, and the two equipment can determine the fixed time slot of the final transmission data based on the channel time slot information of the two equipment and the allocated transmission time slot. Of course, the specific negotiation principle may be preset, and is not listed here.
In this embodiment, considering the crossing rule, there is also a case where the allocated transmission slot is not adapted, and the transmission slot may be determined by a preset rule. For example, the transmission slots allocated to the SPN device 3 are 3 th to 5 th slots, and the transmission slots allocated to the SPN device 4 are 3 th to 5 th slots, but according to the crossing rule, the 3 rd to 5 th slots of the SPN device 3 correspond to the 2 nd to 4 th slots of the SPN device 4, and based on the crossing rule, priority is given to the SPN device 4, and if the 2 nd slot of the SPN device 4 is free, the SPN device 4 performs transmission using the 2 nd to 4 th slots. Of course, the preset rule is not limited to the above-mentioned priority of the intersection rule, and is not listed here.
Optionally, the channel timeslot information includes a time-slotted identifier, a channel serial number used for transmission, and a timeslot map of a current channel.
Thus, whether the time-slotted mode is supported can be known through the time-slotted mode identification, and the channel serial number used for transmission and the time slot map of the current channel can be convenient to know which time slots are occupied and which time slots are free (occupied is 1 and free is 0).
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:
Figure BDA0001823952110000091
TABLE 1
If the channel time slot information time slot identification knows that the SE channel of the SPN equipment does not support time slot, the received data is sent in a random time slot.
In this embodiment, the SE channel slotted transmission state machine is shown in fig. 3, channel slot information is exchanged between SPN devices, and the SPN devices first know whether the opposite end supports slotted according to the slotted identifier. And if not, sending the received data in the random time slot. If so, further judging whether the time slots are aligned, and under the condition of alignment, transmitting and receiving data in a fixed time slot by combining a channel serial number and a time slot diagram with a transmission time slot allocated by an SDN controller; in case of misalignment, the transceiver side negotiation is performed until alignment, and FlexE OH is updated after the negotiation is completed.
In summary, in the data transmission method according to the embodiment of the present invention, data to be transmitted is transmitted through a fixed time slot in an SE channel, so that corresponding service data (i.e., data to be transmitted for the same service) is transmitted in the SE channel of the SPN device due to the fixed time slot.
As shown in fig. 4, a data transmission method according to an embodiment of the present invention is applied to a transmission control device, and includes:
step 401, receiving a service data transmission application;
step 402, determining transmission configuration information of a target SPN device according to the service data transmission application and channel time slot information of the target SPN device, and sending the transmission configuration information to the target SPN device so as to transmit data to be transmitted to a receiving end through a fixed time slot in a layered Ethernet channel of the target SPN device; the transmission configuration information includes a transmission slot allocated to the service data transmission application.
Through the steps, after receiving a service data transmission application, the transmission control device applying the method of the embodiment of the invention determines the transmission configuration information of the target SPN device according to the service data transmission application and the channel time slot information of the target SPN device, and sends the transmission configuration information to the target SPN device so as to transmit the data to be transmitted to a receiving end through the fixed time slot in the layered Ethernet channel of the target SPN device; the transmission configuration information includes a transmission slot. Therefore, time-slotted transmission of the SE channel can be realized, idle time slots are effectively utilized, the utilization rate of the SE channel is improved, and flexible up-down and transmission of services are realized.
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. The target SPN device applies for the relevant SPN device corresponding to the service for the service data transmission, and the channel time slot information is used for indicating the use state of the current SE channel of the SPN device, so that the transmission configuration information capable of better utilizing the idle time slot can be determined and provided by the service data transmission application and the channel time slot information of the target SPN device together for utilizing the idle time slot. Of course, the transmission configuration information is sent to the target SPN device.
Optionally, the method further comprises:
and receiving channel time slot information sent by the SPN equipment.
This step receives the channel time slot information sent by the SPN device, and may include the channel time slot information of the SPN parent device and the SPN child device of the SPN device in addition to the channel time slot information of the SPN device itself, so that the transmission control device preferably selects an applicable transmission time slot in combination with the time slot state of the relevant SPN device of the service. 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 time-slotted identifier, a channel serial number used for transmission, and a timeslot map of a current channel.
Thus, whether the time-slotted mode is supported can be known through the time-slotted mode identification, and the channel serial number used for transmission and the time slot map of the current channel can be convenient to know which time slots are occupied and which time slots are free (occupied is 1 and free is 0).
Specifically, the channel timeslot information is carried in a flexible ethernet header message.
In this way, the SPN device transmits data, may carry channel time slot information through 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 above and will not be described here.
To sum up, in the data transmission method according to the embodiment of the present invention, after receiving a service data transmission application, according to the service data transmission application and channel timeslot information of a target SPN device, transmission configuration information of the target SPN device is determined and sent to the target SPN device, so that data to be transmitted is transmitted to a receiving end through a fixed timeslot in a layered ethernet channel of the target SPN device; the transmission configuration information includes a transmission slot. Therefore, time-slotted transmission of the SE channel can be realized, idle time slots are effectively utilized, the utilization rate of the SE channel is improved, and flexible up-down and transmission of services are realized.
