Background
Modern data center applications require high throughput up to millisecond delays and Gbps levels to meet customer needs. In the context of explosive growth of internet data, network transport for data center applications is faced with very great challenges, including congestion and queue overflow. These problems tend to result in unexpected packet loss from the network transmission, thereby compromising the performance of the network application. In order to solve the problems of packet loss and performance degradation in network transmission, many large-scale data centers have begun to adopt lossless ethernet technology, which can avoid unexpected packet loss in network transmission: the use of PFC (Priority-based Flow Control), also known as class-based flow control, in the network side is used in the network side. Is a queue-based backpressure mechanism that prevents buffer overflow from dropping packets by sending a pause frame that informs an upstream device of a forwarding device to pause sending packets.
However, when the lossless ethernet technology is adopted to perform data transmission, the problem that when a pause frame is triggered, an uncongested port in the forwarding device is stopped by an upstream device to perform data transmission and reduce the data transmission quality is faced, and therefore, a method capable of improving the data transmission quality is needed.

Fig. 2 shows a flowchart of a data transmission control method in an embodiment of the present disclosure, and as shown in fig. 2, the data transmission control method provided in the embodiment of the present disclosure includes the following steps:
s202, sending a network quality polling data packet to each forwarding node on the data transmission link, wherein the network quality polling data packet is used for triggering each forwarding node to feed back transmission quality information of transmission data.
The network quality polling data packet is a data packet sent by the data sending end or the network quality polling device to each forwarding node on the data transmission link, and is used for triggering each forwarding node to enable the forwarding node to acquire own transmission quality information.
In some embodiments, when the network quality poll packet is transmitted by the data transmitting end, the data transmitting end transmits the network quality poll packet to each forwarding node while in an idle state in which no traffic packet is transmitted.
In some embodiments, when the network quality polling packet is transmitted by the network quality polling device, the network quality polling device periodically transmits the network quality polling packet to each forwarding node on the data transmission link according to a preset network quality polling packet generation period.

S206, determining whether the transmission quality of the data transmitted by each forwarding node meets the preset transmission control condition according to the network quality response data packet fed back by each forwarding node.
When the preset transmission control condition is that the length of a data packet forwarding queue recorded in a network quality response data packet fed back by a forwarding node exceeds a preset length threshold; or when the number of the sent network quality polling data packets reaches a preset threshold value of the number of the network quality polling data packets, no forwarding node feeds back the network quality response data packets.
And S208, when the transmission quality of the first forwarding node meets the preset transmission control condition, transmitting a transmission control frame to a second forwarding node to control the second forwarding node to transmit a data packet to the first forwarding node, wherein the first forwarding node is any forwarding node on the data transmission link, and the second forwarding node is an upstream node of the first forwarding node.
It should be noted that, when the transmission quality of any forwarding node (i.e., the first forwarding node) on the data transmission link meets the preset transmission control condition, the length of the data packet forwarding queue in the first forwarding node is reduced by controlling the data packet sent by the second forwarding node (i.e., the upstream node of the first forwarding node) to the first forwarding node, so as to improve the transmission quality.
As an alternative embodiment, when the network quality poll packet is sent by the data sending end, a schematic diagram of the data sending end sending the network quality poll packet to the data receiving end is shown in fig. 3. Referring to fig. 3, a data transmitting end transmits a network quality polling data packet to a data receiving end through a data transmission link, after each forwarding node in the data transmission link receives the network quality polling data packet, the data transmitting end acquires own transmission quality information to construct a corresponding network quality response data packet, and transmits the corresponding network quality response data packet to the data transmitting end, so that the data transmitting end judges the transmission quality of each forwarding node according to the received network quality response data packet.
Fig. 4 is a flowchart illustrating a method for determining whether transmission quality of data transmitted by each forwarding node meets a preset transmission control condition according to an embodiment of the present disclosure, as shown in fig. 4, where the method for determining transmission quality of data transmitted by each forwarding node according to an embodiment of the present disclosure includes the following steps:

The target network quality response data packet is a transmission quality response data packet with the length of a data packet forwarding queue exceeding a preset length threshold, which indicates that more data packets are cached by a forwarding node sending the target network quality response data packet, so that data blocking is easy to generate and the transmission quality is affected.
In some embodiments, after sending the network quality poll packet to each forwarding node on the data transmission link, the data transmission control method provided in the embodiments of the present disclosure may further include: if the number of the sent network quality polling data packets reaches a preset network quality polling data packet number threshold value and network quality response data packets fed back by any forwarding node are not received yet, determining that the data transmission link is abnormal, and outputting prompt information that the data transmission link is abnormal.

Fig. 6 is a flowchart illustrating a transmission control frame being sent to a second forwarding node to control a data packet sent by the second forwarding node to a first forwarding node in an embodiment of the present disclosure, as shown in fig. 6, and the step of sending the transmission control frame to the second forwarding node to control the data packet sent by the second forwarding node to the first forwarding node in an embodiment of the present disclosure includes:
S602, acquiring priority information of a data packet sent by a second forwarding node to a first forwarding node.
Among the data packets sent by the second forwarding node to the first forwarding node, the data packet corresponding to the high priority information is prioritized over the data packet corresponding to the low priority information and is transmitted.
S604, acquiring the occupancy rate of a forwarding queue of the data packet corresponding to the information of different priorities.
When the second forwarding node sends the data packets to the first forwarding node, the data packets corresponding to the same priority information are transmitted by adopting the same forwarding queue, and the occupancy rate of the forwarding queues of the data packets corresponding to the different priority information is counted according to the occupancy rate.

When the occupancy rate of the forwarding queue of the data packet corresponding to the information with different priority reaches the occupancy rate threshold of the forwarding queue corresponding to the data packet, the data transmitting end transmits a pause frame to the second forwarding node through the data transmission link so that the second forwarding node stops transmitting the data packet corresponding to the priority information to the first forwarding node.
And S610, if the occupancy rate of the forwarding queue of the data packet corresponding to the different priority information reaches a preset forwarding stop threshold, controlling the second forwarding node to pause sending the data packet to the first forwarding node.
Before starting data transmission, a forwarding stop threshold is set, and when the occupancy rate of a forwarding queue of a data packet corresponding to any priority information in the data packet sent by the second forwarding node to the first forwarding node reaches the forwarding stop threshold, the data transmission from the second forwarding node to the first forwarding node is suspended.
As an alternative embodiment, after controlling the second forwarding node to suspend sending the data packet to the first forwarding node, the first forwarding node continues sending the data packet to its downstream node, and resumes the second forwarding node to send the data packet to the first forwarding node when the first forwarding node reduces the occupancy of the forwarding queue, which itself reaches the forwarding stop threshold by sending the data packet to its downstream node, to the forwarding start threshold set before starting the data transmission.
