Description

A data scheduling method, terminal and storage medium

Technical field

The present application relates to the field of communications, and in particular, to a data scheduling method, terminal and storage medium.

Background technique

Many hosts today are multi-homed. Therefore, they have multiple paths for connectivity via one or more access technologies, and common Transmission Control Protocol (TCP)/Internet Protocol (IP) communication limits these multi-homed hosts. Each session uses only one of the available interfaces/paths, where a path is defined as a (source, destination) IP address pair. The Internet Engineering Task Force (IETF) is currently working on a mechanism to simultaneously use multiple paths between communication peers during a communication session. IETF Request For Comments (RFC) number 6843 proposes a set of extensions to traditional TCP for multipath operation when multiple addresses are available. This is called Multi Path Transmission Control Protocol (MPTCP).

The existing MPTCP scheduling mechanism uses the Round-Trip Time (RTT) of each sub-flow as the standard to judge the quality of each sub-flow, which will lead to low accuracy of route selection, thereby affecting the rate of data scheduling.

Detailed ways

It should be understood that the specific embodiments described herein are merely illustrative of the present application. It is not intended to limit this application.

End-to-end devices place data on multiple sub-streams for parallel transmission through MPTCP. With the joint utilization of multiple interfaces, the throughput and robustness of data transmission can be improved. When allocating data between multiple sub-flows, MPTCP needs to pre-select sub-flows among multiple available sub-flows. It needs to discard sub-flows with poor quality and select sub-flows with better quality to reduce the path distance. differences in transmission quality. On the one hand, if the sending end does not discard poor sub-streams during multi-path transmission, data transmission on this sub-stream will easily cause problems such as data packet timeout, errors, packet loss, and retransmission, and the receiving end will The data packets received on the sub-flow are sorted and combined. Even if the data transmission on other sub-flows is normal, the delayed arrival of the data packets on the sub-flow will lead to incomplete data, resulting in delayed delivery to the upper application, and then Affects the overall transmission performance of MPTCP between the sender and receiver. On the other hand, if the transmission quality difference between sub-streams is too large, due to the lack of data packets carried by the poor sub-stream, the data packets received on the better sub-stream will quickly fill the data buffer of the receiving end, resulting in the loss of the data packets carried by the better sub-stream. There are problems with data suspension on the stream and timeout retransmission of a large amount of data. Therefore, during the MPTCP data transmission process, it is very important to schedule the data to a reasonable sub-path.

The existing solution to measure the status and quality of subflows based on the RTT of the subflow does not fully consider the data transmission performance and the amount of data transmission that can be carried in the current network environment. Therefore, in order to ensure the overall transmission capability of MPTCP , when setting the business scheduling strategy, it is necessary to fully consider the data transmission performance and the amount of data transmission that can be carried in the current network environment, and then set the MPTCP data transmission scheduling strategy according to the differentiated network environment. This application is specifically described through the following examples.

Embodiment 1

This embodiment of the present application provides a data scheduling method, as shown in Figure 1. The method may include:

S101. Obtain the current network standard corresponding to the currently registered mobile network.

The data scheduling method provided by the embodiment of the present application is suitable for the scenario of scheduling TCP flows between two terminals with MPTCP capabilities.

In this embodiment of the present application, the terminal can be any device with communication and storage functions, such as a tablet computer, a mobile phone, a personal computer (Personal Computer, PC), a notebook computer, a wearable device, and other devices.

The terminal in the embodiment of this application has MPTCP capabilities, and the terminal establishes an MPTCP connection with the opposite end. At this time, multiple transmission substreams are established between the terminal and the opposite end. At the same time, the terminal decomposes the byte stream received from the application into TCP segment, the terminal determines the target transmission substream from multiple transmission substreams according to the current network standard corresponding to the currently registered mobile network, so as to schedule the TCP segment using the target transmission substream.

In this embodiment of the present application, the terminal obtains the current network standard corresponding to the mobile network currently registered by the terminal in real time. Among them, the current network standards may include: Stand Alone (SA)/Non-Stand Alone (NSA), Long Term Evolution (LTE), and third-generation mobile communication technology (3rd-Generation). , 3G), Time Division-Synchronous Code Division Multiple Access (TD-SCDMA), etc. The specific selection is based on the actual situation and is not specifically limited in the embodiments of this application.

In the embodiment of this application, different network standards have different data transmission performances. The terminal sets different data scheduling policies for different network standards according to the data transmission performance corresponding to the network standard. When the terminal obtains the current data corresponding to the currently registered mobile network, After determining the network standard, the terminal determines the data scheduling policy corresponding to the current network standard.

S102. Based on the current network standard, determine the target transmission substream from at least two transmission substreams, and prioritize data to be transmitted via the target transmission substream.

After the terminal obtains the current network standard, the terminal determines the target transmission substream from at least two transmission substreams based on the data scheduling policy corresponding to the current network standard, and prioritizes scheduling of data to be transmitted via the target transmission substream.

In the embodiment of this application, the terminal divides the network standard into three parts according to the network quality. These three parts include: a first network standard set, a second network standard set and a third network standard set, where the first network standard set The network quality of the medium network standard is higher than the network quality of the network standards in the second network standard set, and the network quality of the network standards in the second network standard set is higher than the network quality of the network standards in the third network standard set.

In the embodiment of this application, the network quality of the network standard includes: transmission rate, delay, capacity, connection volume and other parameters. The specific parameters can be selected and increased according to the actual situation. The embodiment of this application does not make specific limitations.

In the embodiment of the present application, the network standards in the first network standard set, the second network standard set and the third network standard set can be modified and added accordingly according to the actual situation, and are not specifically limited in the embodiment of the present application.

Exemplarily, network standards are divided according to their data transmission capabilities, where the network standards in the first network standard set are SA/NSA, the network standards in the second network standard set are LTE and 3G, and the third network standards are The network standards in the standard set are 2G and so on. The data transmission rate of NSA/SA is 10 times that of LTE. That is, the time spent by NSA/SA to transmit the same size data stream is only a few tenths of that of LTE. Similarly, The data transmission rate of LTE is dozens of times that of TDSCDMA and WCDMA.

In the embodiment of this application, the terminal determines the network standard set to which the current network standard belongs. When the current network standard is in the first network standard set, the terminal determines that the current network standard is a high-quality network standard. At this time, the terminal transmits the cell The stream is determined as the target transmission substream, and the data to be transmitted is scheduled via the Cell substream first; when the current network standard is in the third network standard set, the terminal determines that the current network standard is a low-quality network standard. At this time, the terminal will Wi- The Fi transmission substream is determined as the target transmission substream, and data to be transmitted is scheduled via the Wi-Fi substream.

In this embodiment of the present application, the at least two transmission substreams may include a cell transmission substream and a wireless broadband (Wireless-Fidelity, Wi-Fi) transmission substream, where the number of cell transmission substreams is at least one, and the Wi-Fi transmission substream The number of substreams is at least one.

Furthermore, the network standard in the third network standard set has the lowest data transmission rate and cannot carry a data transmission process with a large amount of data. Therefore, when the current network standard is in the third network standard set, the terminal is prohibited from transmitting substreams through the cell. Schedule data to be transmitted.

For example, when the network standard of the current registered network of the terminal is 2G, the terminal is prohibited from scheduling data to be transmitted via the Cell subflow.

In the embodiment of this application, when the current network standard is in the second network standard set, the terminal obtains the transmission parameters of the cell transmission substream and the Wi-Fi transmission substream respectively, and uses the transmission parameters of the cell transmission substream and the Wi-Fi transmission substream. - The transmission parameters of the Fi transmission substream, and the target transmission substream is determined from at least two transmission substreams. Specifically, the terminal compares the transmission parameters of the cell transmission substream with the transmission parameters of the Wi-Fi transmission substream to obtain the comparison result; calculates the difference between the transmission parameters of the cell transmission substream and the transmission parameters of the Wi-Fi transmission substream. Parameter difference; determine the target transmission sub-stream from at least two transmission sub-streams based on the comparison result and the parameter difference.

In the embodiment of this application, the transmission parameters of the transmission sub-stream can be RTT values, transmission channel congestion-related parameters and other parameters that can characterize the transmission characteristics of the transmission sub-stream. The specific selection is based on the actual situation. The embodiment of this application does not make specific limited.

In an optional embodiment, when the current network standard is LTE, the terminal obtains the RTT value of the Cell substream and the RTT value of the Wi-Fi substream respectively. After that, the terminal obtains the RTT value of the Cell substream and the Wi-Fi substream. Compare the RTT value of the Fi subflow and obtain the RTT difference between the Cell subflow and the Wi-Fi subflow. When the RTT value of the Cell subflow is less than the RTT value of the Wi-Fi subflow, and the Cell subflow and the Wi-Fi subflow are -When the RTT difference between the Fi subflows is greater than the preset threshold, the terminal determines the Cell subflow as the target transmission subflow; when the RTT value of the Cell subflow is less than the RTT value of the Wi-Fi subflow, and the Cell subflow and When the RTT difference between Wi-Fi subflows is less than the preset threshold, the terminal determines the Wi-Fi subflow as the target transmission subflow; when the RTT value of the Cell subflow is greater than the RTT value of the Wi-Fi subflow, the terminal Determine the Wi-Fi subflow as the target transmission subflow.

In another optional embodiment, when the current network standard is 3G, the terminal obtains the RTT value of the Wi-Fi subflow and compares the RTT value of the Wi-Fi subflow with the preset 250ms. When the Wi-Fi subflow -When the RTT value of the Fi subflow is less than 250ms, the terminal determines the Wi-Fi subflow as the target transmission subflow; when the RTT value of the Wi-Fi subflow is greater than 250ms, the terminal further combines the RTT value of the Cell subflow with the Wi-Fi subflow. Compare the RTT value of the Fi subflow and obtain the RTT difference between the Cell subflow and the Wi-Fi subflow. Specifically, when the RTT value of the Cell subflow is less than the RTT value of the Wi-Fi subflow, and the Cell subflow When the RTT difference between the flow and the Wi-Fi subflow is greater than the preset threshold, the terminal determines the Cell subflow as the target transmission subflow; when the RTT value of the Cell subflow is less than the RTT value of the Wi-Fi subflow, and the Cell subflow When the RTT difference between the subflow and the Wi-Fi subflow is less than the preset threshold, the terminal determines the Wi-Fi subflow as the target transmission subflow; when the RTT value of the Cell subflow is greater than the RTT value of the Wi-Fi subflow When, the terminal determines the Wi-Fi subflow as the target transmission subflow.

It should be noted that the above are only two optional implementation methods for the terminal to determine the target transmission substream from at least two transmission substreams based on the RTT transmission parameters of the at least two transmission substreams. The embodiments of the present application are not limited to the above. Two implementation methods, and other deformation schemes that determine the target transmission substream from at least two transmission substreams based on the transmission parameters of the cell transmission substream and the transmission parameters of the Wi-Fi transmission substream are all schemes protected by this application. , there are no specific limitations in the embodiments of this application.

In this embodiment of the present application, the data to be transmitted is a TCP segment.

In the embodiment of the present application, after the terminal determines the target transmission substream, the terminal preferentially schedules the data to be transmitted via the target transmission substream. When there is a large amount of data to be transmitted queued for transmission and there are no TCP segments related to the target transmission substream. In the case of related acknowledgment (ACK) and other situations, the terminal can select other transmission substreams from at least two transmission substreams to take over the scheduling of data to be transmitted, thereby ensuring the continuity and timeliness of data scheduling.

For example, as shown in Figure 2, the flow chart of the terminal's MPTCP data scheduling strategy based on the cellular network standard is:

1. The terminal obtains the current network standard;

2. The terminal determines whether the current network standard is NSA/SA;

3. When the current network format is NSA/SA, the terminal preferentially uses Cell subflow to schedule TCP segments;

4. When the current network standard is not NSA/SA, the terminal determines whether the current network standard is LTE;

5. When the current network standard is LTE, the terminal uses the RTT of the Cell substream and the RTT of the Wi-Fi substream to determine the target transmission substream from the Cell substream and Wi-Fi substream;

6. When the current network standard is not LTE, the terminal determines whether the current network standard is 3G;

7. When the current network standard is 3G, the terminal uses the RTT of the Cell substream and the RTT of the Wi-Fi substream to determine the target transmission substream from the Cell substream and Wi-Fi substream;

8. When the current network standard is not 3G, the terminal preferentially uses Wi-Fi subflow to schedule TCP segments.

It is understandable that different network standards correspond to different data transmission volumes and data transmission performances. The terminal determines the target transmission substream with the highest data transmission performance from at least two transmission substreams based on the data scheduling strategies corresponding to different current network standards. , can improve the accuracy of routing; at this time, when scheduling data via the target transmission sub-flow, higher data transmission performance can increase the rate of data scheduling.
