In the application, a physical transmission channel of a data transmission module is virtualized into a plurality of virtual transmission channels. The virtual transmission channel is a self-defined set of independent data formats associated with a Remote Display Protocol (RDP), and this technology makes it unnecessary to change the RDP and add new functions.
As shown in fig. 1, an embodiment of the present disclosure provides a method for data transmission, including the following steps:
s101: when the data size of the message to be transmitted exceeds a preset value, splitting the message to be transmitted into N primary sub-messages according to the data size or the data structure of the message to be transmitted.
And N is the number of virtual transmission channels of the data transmission module.
The size of the preset value can be customized by those skilled in the art according to actual situations, for example, the value of the preset value is 5000 bytes. When the data size of the message to be transmitted exceeds a preset value, the data size of the message to be transmitted is larger, and the message to be transmitted is split in order to improve the data transmission efficiency of the message to be transmitted, so that the split multiple first-level sub-messages can be transmitted in parallel and synchronously.
Splitting a message to be transmitted into N primary sub-messages according to the data size of the message to be transmitted, namely averagely splitting the message to be transmitted into N primary sub-messages according to the data size of the message to be transmitted; the method includes splitting a message to be transmitted into N primary sub-messages according to a data structure of the message to be transmitted, that is, splitting the message to be transmitted into N primary sub-messages according to relevance of data in the message to be transmitted (for example, splitting data including continuous numbers into the same data packet). Therefore, the splitting mode of the message to be transmitted is more flexible.
S102: and sending the N primary sub-messages to a network side in parallel through N virtual transmission channels.
Wherein, each virtual transmission channel transmits a primary sub-message.
After the message to be transmitted is split into N primary sub-messages, each virtual transmission channel transmits one primary sub-message, so that the message to be transmitted can be transmitted to a network side in parallel and synchronously.
Optionally, the data sizes of the first-level sub-packets are the same or a data size difference between any two first-level sub-packets is smaller than a preset data size difference. The preset data size difference may be preset (e.g., 50 bytes). Therefore, the transmission of each level of sub-message can be completed as synchronously as possible, and the waiting time is shortened.
Optionally, the data size of the first-level sub packet and the maximum transmission unit of the virtual transmission channel satisfy the following relationship:
di≤Di
wherein d isiData size, D, representing the ith primary sub-packetiRepresents the virtual transmission channel T corresponding to the ith primary sub-messageiI-1, …, N.
The Maximum Transmission Unit (MTU) of a virtual Transmission channel refers to the Maximum datagram size (in bytes, for example, 1500 bytes) that the virtual Transmission channel can pass through. This parameter of maximum transmission unit is usually related to the communication interface (network interface card, serial port, etc.). The data size of the first-level sub-message is smaller than or equal to the maximum transmission unit of the virtual transmission channel, so that the first-level sub-message can be smoothly transmitted through the virtual transmission channel.
Optionally, the maximum transmission units of the virtual transmission channels are the same, that is, the physical transmission channel of the data transmission module is virtualized into a plurality of identical virtual transmission channels. In this way, the division of the individual virtual transmission channels is simpler.
By adopting the method for data transmission provided by the embodiment of the disclosure, a plurality of virtual transmission channels are simultaneously established in the data transmission module, the message to be transmitted is split into a plurality of primary sub-messages, and the plurality of primary sub-messages are respectively sent to the network side in parallel through the plurality of virtual transmission channels. The data transmission module may be a WIFI module, and this embodiment may implement data transmission through a plurality of virtual transmission channels of only one WIFI module. Therefore, the number of the data packets sent in unit time is increased, and the problem of data delay caused by long-term waiting of a receiver due to overlarge data packets can be solved well.
In some embodiments, the method for data transmission further comprises: and when the data size of the message to be transmitted does not exceed the preset value, the message to be transmitted is sent to the network side through a preset virtual transmission channel.
When the data size of the message to be transmitted does not exceed the preset value, the data size of the message to be transmitted is small, the message can be directly transmitted through a preset virtual transmission channel (for example, the first virtual transmission channel with the number of 1) without unpacking the data, the splitting process of the message to be transmitted is omitted, and the transmission time of the data is shortened to a certain extent.
In some embodiments, when d is present, as shown in FIG. 2i>DiThe method for data transmission further comprises the steps of:
s201: and splitting the ith primary sub-message into a plurality of secondary sub-messages.
Wherein the data size of each secondary sub-message is less than or equal to Di。
Optionally, splitting the ith primary sub-packet into a plurality of secondary sub-packets, including: determining the number M (M) of secondary sub-messages according to the data size of the ith primary sub-message and the maximum transmission unit of the ith virtual transmission channel1) (ii) a Splitting the ith primary sub-message into M1And each secondary sub-message has a data size equal to the maximum transmission unit of the ith virtual transmission channel.
The number of the secondary sub-messages can be calculated by the following formula:
wherein S isiFor the ith primary sub-message, S0Is the maximum transmission unit of the ith virtual transmission channel, SiCan be covered by S0And (4) trimming.
For example, the data size of the 1 st primary sub-packet is 3000 bytes, the maximum transmission unit of the 1 st virtual transmission channel is 1500 bytes, and the number of the secondary sub-packets is 2. And splitting the 1 st primary sub-message into 2 secondary sub-messages with the data size of 1500 bytes.
Optionally, splitting the ith primary sub-packet into a plurality of secondary sub-packets, including: determining the number M (M) of secondary sub-messages according to the data size of the ith primary sub-message and the maximum transmission unit of the ith virtual transmission channel2) (ii) a Splitting the ith primary sub-message into M2A second level sub-message, wherein (M)2-1) the data size of the second level sub-packet is the maximum transmission unit of the ith virtual transmission channel, and the data size of the 1 second level sub-packet is (S)i+S0-M2×S0)。
The number of the secondary sub-messages can be calculated by the following formula:
wherein S isiFor the ith primary sub-message, S0Is the maximum transmission unit of the ith virtual transmission channel, SiCan not be covered by S0And (4) trimming.
For example, the data size of the 1 st primary sub-packet is 3500 bytes, the maximum transmission unit of the 1 st virtual transmission channel is 1500 bytes, and the number of the secondary sub-packets is 3. The 1 st primary sub-message is split into 2 secondary sub-messages with the data size of 1500 bytes and 1 secondary sub-message with the data size of 500 bytes.
S202: and serially transmitting the split secondary sub-messages to a network side through the ith virtual transmission channel.

In some embodiments, when the maximum transmission units of the virtual transmission channels are different, the method for data transmission further includes: adjusting part of secondary sub-messages in a plurality of secondary sub-messages corresponding to an mth virtual transmission channel to an nth virtual transmission channel for transmission, so that the number of the secondary sub-messages corresponding to the mth virtual transmission channel is the same as the number of the secondary sub-messages corresponding to the nth virtual transmission channel or the number difference is smaller than a preset number difference, wherein m is 1, … or N, N is 1, … or N, and m is not equal to N; the initial number of the second-level sub-messages corresponding to the mth virtual transmission channel is greater than the initial number of the second-level sub-messages corresponding to the nth virtual transmission channel, and the data size of each second-level sub-message is smaller than or equal to the maximum transmission unit of the minimum virtual transmission channel. The preset number difference may be preset (e.g., 1).
For example, the maximum transfer unit of the first virtual transfer channel is 1000 bytes, the maximum transfer unit of the first virtual transfer channel is 1500 bytes, and the maximum transfer unit of the first virtual transfer channel is 2500 bytes. When the data size of the first-level sub-packet is 3500 bytes, the number of the second-level sub-packets corresponding to the first virtual transmission channel is 4, the number of the second-level sub-packets corresponding to the second virtual transmission channel is 3, and the number of the second-level sub-packets corresponding to the third virtual transmission channel is 2, then 1 of the second-level sub-packets corresponding to the first virtual transmission channel is adjusted to the third virtual transmission channel for transmission.
In the embodiment of the disclosure, the transmission quantity of the secondary sub-packets corresponding to each virtual transmission channel is adjusted, so that the secondary sub-packets can be transmitted in parallel and synchronously, and the data volume of the packet to be transmitted sent in unit time is further improved, thereby better solving the problem of data delay of long-term waiting of a receiver due to overlarge data packets.
In some embodiments, as shown in fig. 3, the method for data transmission further comprises the steps of:
s301: and carrying out primary numbering on the primary sub-message according to the number of the virtual transmission channel corresponding to the primary sub-message.
When a physical transmission channel of the data transmission module is virtualized into a plurality of virtual transmission channels, each virtual transmission channel is numbered in sequence, for example, a first virtual transmission channel, a second virtual transmission channel, and a third virtual transmission channel. Correspondingly, the first-level sub-message transmitted through the first virtual transmission channel is numbered as 1; the first-level sub-message transmitted through the second virtual transmission channel is numbered as 2; and performing primary numbering for the primary sub-message transmitted through the third virtual transmission channel to be 3.
S302: and if the primary sub-message is split into a plurality of secondary sub-messages, performing secondary numbering on each secondary sub-message on the basis of the primary numbering.
