Background
With the continuous development of communication technology, the requirements of users on communication quality are higher and higher. There are many communication services that are very sensitive to delay and packet loss, for example: instant messaging type services.
In the prior art, a Forward Error Correction (FEC) -based packet loss prevention method is generally used to solve the problem of poor service quality caused by packet loss in an information transmission process.

In the existing scheme, whether the FEC function of the receiving end is normal is judged by regularly sending the FEC detection message to the receiving end device, however, regularly sending the FEC detection message to the receiving end device occupies a large bandwidth, thereby causing waste of communication resources.

Detailed Description
In order that the above-mentioned objects, features and advantages of the present application may be more clearly understood, the solution of the present application will be further described below. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present application may be practiced otherwise than as specifically described herein; it is to be understood that the embodiments described in this specification are only some embodiments of the present application and not all embodiments.
Relational terms such as "first" and "second," and the like, may be used throughout the description and claims of the present application to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. For example, the first device, the second device, the third device, and the like are used to distinguish the devices as the sending device or the receiving device, and are not ordering between the devices.
In the embodiments of the present application, the words "exemplary" or "such as" are used herein to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present relevant concepts in a concrete fashion.
The overall concept of the embodiment of the application is as follows: when the FEC function status of the sending end device changes, the receiving end device is notified. Firstly, detecting whether the FEC function of a receiving end is started or not; when the FEC function of the receiving end is detected to be in an open state, the FEC detection message does not need to be sent to the receiving end equipment at regular time to detect whether the FEC function of the receiving end equipment is opened or not, and only the message containing the original message and the redundant message needs to be sent, so that the bandwidth occupation in the message communication process is reduced, and the communication resource is saved.
In one embodiment, as shown in fig. 1, a data transmission method is provided, which includes the following steps:
s11, when the Forward Error Correction (FEC) function of the first equipment is started, detecting whether the FEC function of the second equipment is started.
For example, when the first device is used as a transmitting end, the second device may be used as a receiving end. When the FEC function of the sending end is started, whether the FEC function of the receiving end is started or not is detected.
S12, if the FEC function of the second equipment is determined to be started, FEC encoding is carried out on the original message to generate a redundant message, and a message comprising the original message and the redundant message is sent to the second equipment.
Specifically, if it is determined that the FEC function of the second device is turned on, the second device may perform FEC encoding and decoding operations. It can be understood that, when the FEC functions of the first device and the second device are both turned on, both the sending end and the receiving end can perform FEC encoding and decoding operations. The sending end equipment encodes the original message to generate a redundant message, and then sends a message containing a message header, the original message and the redundant message to the receiving end equipment.
It should be noted that, since FEC is implemented by adding redundant information to the transmitted data information based on an algorithm, the value of one redundant bit may be a complex function of many information bits in the original information. After encoding, the original information may or may not exist as such.
S13, if the FEC function of the second equipment is not started, sending a message including the original message to the second equipment, and detecting whether the FEC function of the second equipment is started again after a first preset time length.
Illustratively, if the FEC function of the receiving end device is not turned on, the original packet is not encoded at the sending end, the original packet is directly sent to the receiving end, and it is detected again whether the FEC function of the receiving end is turned on after a first preset time period. The first preset time period may be any time interval in the range of 20 to 40 minutes, or other reasonable values, and is not limited in particular.
As an optional implementation manner of this embodiment of the application, as shown in fig. 2, an implementation manner of the step S11 of detecting whether the FEC function of the second device is turned on may include:
s111, sending the FEC detection message for N times to the second equipment.
Wherein N is an integer greater than 1. Illustratively, N generally ranges from: n is more than or equal to 3 and less than or equal to 5, and other reasonable numerical values can be taken according to the actual situation of message communication.
Specifically, the first device sends an FEC detection packet to the second device. The FEC detection message is used to detect whether an FEC function of the second device is started.
S112, if an FEC detection response packet sent by the second device is received, determining that an FEC function of the second device is started, and stopping sending the FEC detection packet to the second device.
Correspondingly, the first device detects whether the FEC detection response message sent by the second device is received. Exemplarily, if the first device receives an FEC detection response packet sent by the second device, it determines that the FEC function of the second device is in an on state, and stops sending the FEC detection packet to the second device.
S113, if none of the detection messages sent to the second device for N consecutive times receive an FEC detection response message, determining that the FEC function of the second device is not turned on.
For example, if the receiving end device does not turn on the FEC function, the receiving end device will not send the probe response message. If the sending end does not receive the FEC detection response message sent by the receiving end equipment after 5 seconds, the sending end sends the FEC detection message to the receiving end equipment again, if the sending end does not receive the FEC detection response message for three times, the FEC function of the receiving end equipment is determined not to be started, and the sending end equipment stops sending the FEC detection message to the receiving end equipment.
As an optional implementation manner in this embodiment of the present application, after S112, it is determined that the FEC function of the second device is turned on, the following steps are further performed:
s112-a, when the FEC functional state of the first device is switched from the on state to the off state, detecting whether the second device has acquired the FEC functional state of the first device, and switching from the on state to the off state.
For example, when the FEC functional state of the transmitting end is switched from an on state to an off state, in a case where the first device serves as the transmitting end and the second device serves as the receiving end, whether the receiving end acquires that the FEC functional state of the transmitting end is switched from the on state to the off state is detected.
And S112-b, if not, sending a message including the original message to the second equipment, and detecting whether the second equipment has acquired the FEC function state of the first equipment again after a second preset time length, wherein the FEC function state is switched from an open state to a closed state.
The second preset time period may be any time period from 20 to 40 minutes, or may be other reasonable time intervals. For example, after 30 minutes, the first device resends the status message to the second device.
Specifically, the FEC functions of the sending end device and the receiving end device can both perform encoding and decoding operations in an open state, for example, the second device receives a message encoded by the first device and decodes the message sent by the first device; similarly, the first device receives the encoded message sent by the second device, and decodes the message sent by the second device. If the FEC function of a certain device is switched from the on state to the off state, the encoding operation is not performed any more, for example, when the FEC function of the first device is in the off state, the first device cannot encode the original message at this time, and only can send a message including the original message to the second device.
Exemplarily, if the first device does not acquire the FEC function state of the second device, the FEC function state is switched from the on state to the off state, a message including only an original message is sent, and the first device is only a function of forwarding data at this time; and then re-detecting whether the second device has acquired the FEC function status of the first device after 30 minutes to switch from the on status to the off status.
And S112-c, if so, stopping decoding the message sent by the second equipment, and continuing to send the message including the original message to the second equipment.
Exemplarily, if the receiving end acquires that the FEC functional state of the sending end is switched from the on state to the off state, since the FEC functional state of the sending end device is the off state, the sending end device only has a function of forwarding data, and thus the sending end device sends a message only including an original message; at this time, the receiving end decodes the message sent by the sending end, after the message sent by the sending end is processed, the FEC function state obtained by the receiving end is fed back to the sending end, and the FEC function state is switched from the on state to the off state, and the decoding is stopped.
In this embodiment, through the FEC status detection mechanism, the opposite device is only notified when the FEC functional status of the sending end or the receiving end device changes, so as to avoid sending the probe packet at regular time, reduce the bandwidth occupation, and save the communication resources.
As an optional implementation manner of this embodiment of the present application, the implementation manner of S112-a, detecting whether the second device has acquired that the FEC functional state of the first device is switched from the on state to the off state, may include:
(1) And sending the FEC state message to the second equipment for M times.
Wherein M is an integer greater than 1. Illustratively, M generally takes the value range: m is more than or equal to 3 and less than or equal to 5, and other reasonable values can be taken according to the actual situation of message communication.
Specifically, the first device sends a status message to the second device, where the status message is used to indicate the FEC functional status of the sending end.
(2) And if an FEC state response message sent by the second equipment is received, determining that the second equipment has acquired the FEC function state of the first equipment and is switched from an open state to a closed state, and stopping sending the FEC state message to the second equipment.
Correspondingly, the status response message is a message responded by the second device in response to the status message sent by the first device. Whether the first equipment receives a state response message sent by the second equipment is detected, and whether the second equipment acquires the FEC function state of the first equipment is detected to be switched from an open state to a closed state.
For example, if the first device receives a status response message sent by the second device, it is determined that the second device has acquired the FEC function status of the first device, and the FEC function status is switched from the on status to the off status.
(3) And if the FEC state response messages are not received in all the FEC state messages sent to the second equipment for M times continuously, determining that the second equipment does not acquire the FEC function state of the first equipment and switching the FEC function state from the open state to the closed state.
For example, assuming that the sending end does not receive the FEC status response message of the receiving end after 5 seconds, the sending end sends the FEC status message to the receiving end again, and if the sending end does not receive the FEC status response message for three consecutive times, it is determined that the second device does not acquire the FEC functional status of the first device, and the sending end switches from the on status to the off status, and stops sending the FEC detection message to the receiving end.
It can be understood that, if the first device does not receive the status response message sent by the second device, the status message is sent to the second device at an interval of a second preset duration.
As an optional implementation manner in this embodiment of the present application, when the first device serves as a receiving end, the following steps are performed:
a. and receiving an FEC detection message sent by the third equipment.
In an embodiment, the first device may also serve as a receiving end, and in this case, the third device may serve as a sending end, and the first device receives the FEC detection packet sent by the third device.
b. And if the FEC function of the first equipment is in an open state, sending an FEC detection response message to the third equipment.
Similarly, if the FEC function of the first device is in the on state, the FEC detection response message is sent to the third device.
c. And if the FEC function of the first equipment is in a closed state, discarding the detection message.
It can be understood that, if the FEC function of the first device is in the off state, the FEC detection message sent by the third device cannot be responded to, and meanwhile, the FEC coding and decoding cannot be performed, and at this time, the FEC detection message may be discarded.
As an optional implementation manner of this embodiment, when the first device serves as a receiving end, the following steps are further performed:
d. and receiving a state message sent by the third equipment.
In one example, the first device serves as a receiving end, and the third device serves as a sending end at this time, and the first device receives the status packet sent by the third device.
e. And if the first equipment has acquired the FEC function state of the third equipment and is switched from the open state to the closed state, sending a state response message to the third equipment.
Correspondingly, if the first device has acquired the FEC function status of the third device and switched from the on status to the off status, a status response message is sent to the third device.
f. And if the first device does not acquire that the FEC function state of the third device is switched from the open state to the closed state, discarding the state message.
It can be understood that, if the first device does not acquire that the FEC functional state of the third device is switched from the on state to the off state, the first device cannot respond to the status packet sent by the third device, at this time, the step of performing FEC decoding on the message including the original packet and the redundant packet may be continuously performed, and the receiving end device does not process the received status packet or discards the status packet.
As an optional implementation manner of this embodiment of the present application, the first preset time period is 20 to 40 minutes, and the second preset time period is 20 to 40 minutes.
In any of the above embodiments, the first preset time period may be any time interval in a range of 20 to 40 minutes, and the second preset time period may be any time interval in a range of 20 to 40 minutes, or other reasonable values according to an application scenario, which is not limited in this respect.

When the FEC function of the first equipment is switched from the closed state to the open state, detecting whether the FEC function of the second equipment is open; when the FEC function of the second equipment is detected to be in the opening state, the FEC sending detection message does not need to be sent to the second equipment at regular time to detect whether the FEC function of the second equipment is opened, and only the message containing the original message and the redundant message needs to be sent, so that the bandwidth occupation in the message communication process is reduced, and the communication resource is saved.
