Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular, to a method and apparatus for information transmission. Background Art

[0002] QUIC (Quick UDP Internet Connections), that is, Quick UDP Network Connections, is a network protocol used in the transport layer, which provides a reliable, secure, and multiplexed transmission method. Multiple streams (STREAMs) can be forwarded in a QUIC connection, and the buffer of the receiving end is set to prevent the sending end from sending data too fast and causing pressure on the receiving end.

[0003] QUIC has two control methods: preventing a single stream from occupying the entire receiving buffer of the connection by restricting the amount of data sent on a single stream, or preventing the total number of bytes of data sent by a connection from exceeding the buffer capacity of the receiving end of the connection. After a QUIC connection is established, when the sum of the available windows of the streams is greater than the buffer capacity of the connection, all packets cannot be sent simultaneously. The QUIC connection randomly selects some streams for sending. For the unselected streams, even if there are available windows, they cannot be sent in time, resulting in a large delay and reducing the user experience. Summary of the Invention

[0041] To make the objectives, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0042] The following will describe Figure 1 the QUIC flow control in the prior art.

[0043] As Figure 1As shown in the figure, a QUIC connection includes multiple sending streams. During the process of sending data over the QUIC connection, part A of the sending stream is the data for which the receiving device has sent an Ack, part B is the data that has been sent but for which the receiving device has not sent an Ack, and part C is the available window space. When the sum of the available window spaces of the sending streams in the QUIC connection is greater than the buffer capacity of the connection, not all sending streams can be sent simultaneously. Only a part of the sending streams can be sent each time, and multiple sending streams are randomly sent. When a certain sending stream is a low-latency service and this sending stream cannot be sent all the time, it will lead to an increase in latency and degrade the user experience.

[0044] To solve the above problems, the present invention provides an information transmission method. Figure 2 The following is a schematic flowchart of the information transmission method provided by the present invention, as Figure 2 shown, including:

[0045] Step 201: Set QoS attributes for the sending stream. The QoS attributes are used to identify the sending priority. When generating the sending stream, set the value of the QoS attribute of the sending stream to a first QoS attribute value, and the first QoS attribute value is used to identify the default sending priority of the sending stream.

[0046] In an embodiment of the present invention, the sending device sets QoS attributes for the sending stream. The QoS attributes are used to identify the sending priority. When generating the sending stream, assign a first QoS attribute value to the QoS attribute of the sending stream, and set a default sending priority for each sending stream to implement the initialization of the QoS attributes.

[0047] When initializing the QoS attributes, uniformly set the first QoS attribute value corresponding to each sending stream to a default value, so that each sending stream has a default sending priority when the QoS attributes are initialized.

[0048] For example, after the receiving device and the sending device establish a QUIC connection, the sending device has three sending streams: voice, video, and his. When generating the three sending streams of voice, video, and his, assign a first QoS attribute value to the QoS attribute of each sending stream, and set the first QoS attribute value corresponding to each sending stream to the default value, and set a default sending priority for each sending stream, thereby implementing the initialization of the QoS attributes of the three sending streams of voice, video, and his.

[0049] Step 202: Negotiate with the receiving device according to a preset rule, and receive a first qos_update message sent by the receiving device, where the first qos_update message is used to indicate that the value of the QoS attribute of the sending stream is updated to a second QoS attribute value.

[0050] In the embodiment of the present invention, the preset rule is formulated according to different receiving scenarios and receiving requirements. Under different receiving scenarios and receiving requirements, the requirements for the sending device to send data and the requirements for the receiving device to receive data are different. By setting the preset rule, and then setting the priority of the sending device to send data, it can effectively make the data sent by the sending device meet different receiving scenarios and receiving requirements.

[0051] Before data is sent, the sending device negotiates with the receiving device according to a preset rule to determine the second QoS attribute value of each sending stream, that is, to determine the sending priority of each sending stream. Before data is sent, the sending priority of each sending stream is determined through negotiation, so that the data sent by the sending end can dynamically adjust the sending order of the sent data according to different receiving scenarios and receiving requirements.

[0052] After determining the sending priority of each sending stream, the receiving device uses the first qos_update message to instruct the sending device to update the QoS attribute value of the sending stream from the first QoS attribute value to the negotiated second QoS attribute value, so that the sending device can determine the corresponding sending priority of each sending stream when the sending device sends data according to the second QoS attribute value.

[0053] For example, after the sending device generates three streams: voice, video, and his, it negotiates with the receiving device. The receiving device determines the sending priority for the three streams: voice, video, and his according to the current receiving scenario and receiving requirements, and instructs the sending device to update the QoS attribute values of the three streams: voice, video, and his through the first qos_update message. The sending device can determine the sending priority of these three streams according to the QoS attribute values corresponding to the three streams: voice, video, and his.

[0054] Step 203: Change the first QoS attribute value of the sending stream to the second QoS attribute value according to the first qos_update message.

[0055] In an embodiment of the present invention, the sending device updates the first QoS attribute value of the sending stream stream to the second QoS attribute value determined through negotiation according to the first qos_update message sent by the receiving device.

[0056] Step 204: Send the sending stream stream according to the second QoS attribute value.

[0057] In an embodiment of the present invention, the sending device determines the sending priority of each sending stream stream according to the second QoS attribute value, and sends each sending stream stream in sequence according to the sending priority.

[0058] The information transmission method provided by the embodiment of the present invention adds QoS attributes to the stream, determines the QoS attribute value of the stream through negotiation between the receiving end and the sending end, determines the sending priority of the stream, and can send the stream differentially according to the sending priority of the stream when sending data in the QUIC connection organization, reducing the delay of data transmission.

[0059] Optionally, the sending priority includes multiple levels, and the first QoS attribute value is one of the multiple levels.

[0060] In an embodiment of the present invention, the sending priority includes multiple levels, and the first QoS attribute value is one of the multiple levels.

[0061] For example, the sending priority includes three priorities: High, Medium, and Low, and the priorities of High, Medium, and Low decrease in sequence, and the first QoS attribute value is one of High, Medium, and Low.

[0062] For example, the sending priority includes four priorities: High, Medium, Nomal, and Low, and the priorities of High, Medium, Nomal, and Low decrease in sequence, and the first QoS attribute value is Nomal.

[0063] Optionally, the sending priority can also be distinguished by letters, numbers, or other means.

[0064] After the sending priority of the sending stream stream is determined, each sending stream stream is sent in sequence according to the priority order. When multiple sending streams stream have the same priority, the multiple sending streams stream with the same priority randomly compete for the available window resources of the sending device.

[0065] It should be noted that the method for distinguishing the sending priority, the ranking rule of the sending priority levels, and the default sending priority can be set as needed, and the embodiments of the present invention do not make specific limitations thereto.

[0066] Optionally, the negotiation with the receiving end device according to a preset rule includes:

[0067] Negotiating with the receiving end device according to the data volume of the sending stream; and / or,

[0068] Negotiating with the receiving end device according to the latency requirement of the sending stream.

[0069] In the embodiments of the present invention, the preset rule is formulated according to different receiving scenarios and receiving requirements. The specific receiving scenarios and receiving requirements may be determined according to the data volume of the sending stream, or may be determined according to the latency requirement of the sending stream, or may be jointly determined according to the data volume of the sending stream and the latency requirement of the sending stream. The embodiments of the present invention do not make specific limitations thereto.

[0070] Figure 3 FIG. is a schematic diagram of a QoS attribute value setting scenario provided by the present invention. The sending priorities corresponding to the voice, video, and his three streams are determined according to the data volume of the sending stream and the latency requirement of the sending stream. As Figure 3 shown, the his stream is for ordinary Internet access. Since the large data volume will affect the sending of other streams, when negotiating between the receiving end device and the sending end device, the QoS attribute of the his stream is given the Nomal priority. The voice stream is voice-related data, and the video stream is video-related data. Since both the voice stream and the video stream have latency requirements, the QoS attributes of the voice stream and the video stream are given the Medium priority, so that the voice stream and the video stream have a higher priority than the his stream, reducing the sending latency of the voice stream and the video stream.

[0071] It should be noted that the sending priorities of the voice, video, and his three streams can also be determined only according to the data volume of the voice, video, and his three streams or the latency requirements of the voice, video, and his three streams.

[0072] Optionally, the first qos-updata message includes the ID of the sending stream and the second QoS attribute value.

[0073] In an embodiment of the present invention, after the sending end device and the receiving end device negotiate to determine the second QoS attribute values corresponding to all the sending streams in the QUIC connection, the receiving end device sends a corresponding first qos-updata message for each sending stream.

[0074] The sending end device updates the QoS attribute value of the sending stream according to the received first qos-updata message. The sending end device can update the QoS attributes of all the sending streams one by one according to the received first qos-updata message, or can screen out the sending streams with different first QoS attribute values and second QoS attribute values according to the received first qos-updata message, and update the QoS attribute values of the screened sending streams.

[0075] Optionally, the sending the sending stream according to the second QoS attribute value specifically includes:

[0076] Determining the sending priority of the sending stream according to the second QoS attribute value;

[0077] Sending the sending stream according to the sending priority.

[0078] Optionally, after the sending the sending stream according to the second QoS attribute value, it further includes:

[0079] When the buffer capacity of the receiving end device is less than the total available window of the sending stream, receiving a second qos-updata message sent by the receiving end device, where the second qos-updata message is used to indicate that the value for updating the QoS attribute of the sending stream is a third QoS attribute value;

[0080] Updating the second QoS attribute value of the sending stream to the third QoS attribute value according to the second qos-updata message;

[0081] Sending the sending stream according to the third QoS attribute value.

[0082] In an embodiment of the present invention, during the process that a sending-end device sends a sending stream according to a sending priority, a receiving-end device may send a second QoS-update message to the sending-end device when the receiving scenario and requirements change, or when the buffer capacity of the receiving-end device is less than the total available window of the sending stream. Through the second QoS-update message, the QoS attributes of each sending stream are dynamically adjusted, and the sending priorities of each sending stream are dynamically adjusted.

[0083] Figure 4 It is a schematic diagram of a QoS attribute value update scenario provided by the present invention. When the buffer capacity of the receiving-end device is less than the total available window of the sending stream, the receiving-end device sends a second QoS-update message to the sending-end device to update the QoS attribute of the sending stream.

[0084] As Figure 4 shown, the voice stream and the video stream have the same priority. When the buffer capacity of the receiving-end device is less than the total available window of the voice stream and the video stream, since the data volume of the voice stream is much smaller than that of the video stream, the receiving-end device sends a second QoS-update message to the sending-end device to inform the sending-end device that the QoS attribute value of the voice stream needs to be updated to the High priority.

[0085] The sending-end device updates the QoS attribute value of the voice stream according to the second QoS-update message. Then, the sending-end device preferentially sends the voice stream according to the updated sending priority. After the voice stream is sent, the video stream is sent, and finally the his stream is sent.

[0086] It should be noted that before the receiving-end device sends a second QoS-update message to update the QoS attribute value of the voice stream, the voice stream and the video stream have the same priority, and the voice stream and the video stream randomly compete for the available window resources of the sending-end device.

[0087] When the receiving device changes the receiving scenario and receiving requirements, the receiving device can send a second QoS-update message to the sending device according to the new receiving scenario and receiving requirements, update the priorities of the voice stream, video stream, and HIS stream, and the sending device sends the voice stream, video stream, and HIS stream according to the new priorities.

[0088] In the embodiment of the present invention, the sending device changes the sending priorities of the respective sending streams by receiving the second QoS-update message, flexibly changes the sending order of the respective sending streams in various situations, effectively reduces the delay of services in the connection, and improves the user experience.

[0089] Optionally, the second QoS-update message includes the ID of the sending stream for which the second QoS attribute value needs to be updated and the third QoS attribute value.

[0090] In the embodiment of the present invention, when the receiving device sends the second QoS-update message, the second QoS-update message is only sent for the sending stream for which the second QoS attribute value needs to be updated, reducing data redundancy and the burden of data transmission in the QUIC connection.

[0091] Optionally, the sending the sending stream according to the third QoS attribute value specifically includes:

[0092] Determining the sending priority of the sending stream according to the third QoS attribute value;

[0093] Sending the sending stream according to the sending priority.

[0094] Figure 5 It is a schematic diagram of the structure of the QoS-update message provided by the present invention. The byte sizes occupied by each part of the QoS-update message are as Figure 5 shown.
