Description
Technical Field
The present application relates to the field of communications, and in particular, to a data scheduling method, a terminal, and a storage medium.
Background
Many hosts are multi-homed today. Thus, they have multiple paths for connection via one or more access technologies, common transmission control protocol (Transmission Control Protocol, TCP)/internet protocol (Internet Protocol, IP) communications, limiting these multi-homed hosts to use only one of the available interfaces/paths per session, where a path is defined as a (source, destination) IP address pair. The internet engineering task force (The Internet Engineering Task Force, IETF) is currently researching mechanisms that use multiple paths between communication peers simultaneously during a communication session. IETF request for comments (Request For Comments, RFC) number 6843 proposes a set of extensions to conventional TCP for multipath operation when multiple addresses are available. This is known as the multipath transmission control protocol (Multi Path Transmission Control Protocol, MPTCP).
The existing MPTCP scheduling mechanism uses Round-Trip Time (RTT) of each sub-stream as a standard to determine the quality of each sub-stream, which may result in low accuracy of routing, thereby affecting the rate of data scheduling.

Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the application. And are not intended to limit the application.
The end-to-end device places the data on a plurality of sub-streams for parallel transmission through MPTCP, and the throughput and the robustness of the data transmission can be improved by means of joint utilization of a plurality of interfaces. When data distribution among a plurality of sub-streams is performed, the MPTCP needs to perform sub-stream selection in advance among a plurality of available sub-streams, and needs to discard sub-streams with poor quality, select sub-streams with better quality, and reduce the difference of transmission quality among paths. On the one hand, if the sender does not discard the worse sub-stream in the multipath transmission process, the data transmission on the sub-stream is easy to cause the problems of overtime, error, packet loss, retransmission and the like of the data packet, the receiver sorts and combines the data packets received on each sub-stream, and even if the data transmission on other sub-streams is normal, the data is incomplete due to the delayed arrival of the data packet on the sub-stream, so that the delay delivery of the upper layer application is caused, and the overall transmission performance of the MPTCP between the sender and the receiver is further affected. On the other hand, if the transmission quality difference between the sub-streams is too large, the data packet carried by the worse sub-stream is missing, and the data packet received on the better sub-stream can quickly fill the data buffer area of the receiving end, so that the problems of data pause and overtime retransmission of a large amount of data on the better sub-stream are caused, and therefore, in the MPTCP data transmission process, it is very important to schedule the data to a reasonable sub-path.
In the prior art, the RTT of the sub-stream is taken as a basis to balance the state and quality of the sub-stream, and the data transmission performance and the data transmission quantity that can be carried in the current network environment are not fully considered, so in order to ensure the overall transmission capability of the MPTCP, when setting the service scheduling policy, the data transmission performance and the data transmission quantity that can be carried in the current network environment need to be fully considered, and then the data transmission scheduling policy of the MPTCP can be set according to the differentiated network environment. The present application is specifically illustrated by the following examples.
Example 1
An embodiment of the present application provides a data scheduling method, as shown in fig. 1, where the method may include:
s101, acquiring a current network system corresponding to a current registered mobile network.
The data scheduling method provided by the embodiment of the application is suitable for a scene of scheduling TCP streams between two terminals with MPTCP capability.
In the embodiment of the present application, the terminal may be any device having communication and storage functions, for example: tablet computers, cell phones, personal computers (Personal Computer, PCs), notebook computers, wearable devices, and the like.
The terminal in the embodiment of the application has MPTCP capability, the terminal and the opposite terminal establish MPTCP connection, at the moment, a plurality of transmission sub-streams are established between the terminal and the opposite terminal, meanwhile, the terminal decomposes the byte stream received from the application into TCP fragments, and the terminal determines a target transmission sub-stream from the plurality of transmission sub-streams according to the current network system corresponding to the current registered mobile network so as to schedule the TCP fragments by using the target transmission sub-stream.
In the embodiment of the application, the terminal acquires the current network system corresponding to the mobile network currently registered by the terminal in real time. The current network system may include: independent networking (SA)/Non-independent Networking (NSA), long term evolution (Long Term Evolution, LTE), third Generation mobile communication technology (3 rd-Generation, 3G), time Division-synchronization code Division multiple access (Time Division-Synchronous Code Division Multiple Access, TD-SCDMA), etc., and the specific selection is made according to the actual situation, and the embodiment of the present application is not limited specifically.
In the embodiment of the application, the data transmission performance of different network modes is different, the terminal sets different data scheduling strategies for different network modes according to the data transmission performance corresponding to the network modes, and after the terminal acquires the current network mode corresponding to the current registered mobile network, the terminal determines the data scheduling strategy corresponding to the current network mode.
S102, determining a target transmission sub-stream from at least two transmission sub-streams based on the current network system, and scheduling data to be transmitted by the target transmission sub-stream preferentially.
After the terminal acquires the current network system, the terminal determines a target transmission sub-stream from at least two transmission sub-streams based on a data scheduling strategy corresponding to the current network system, and schedules data to be transmitted preferentially through the target transmission sub-stream.
In the embodiment of the application, the terminal divides the network system into three parts according to the network quality, wherein the three parts comprise: the system comprises a first network system set, a second network system set and a third network system set, wherein the network quality of a network system in the first network system set is higher than that of a network system in the second network system set, and the network quality of a network system in the second network system set is higher than that of a network system in the third network system set.
In the embodiment of the application, the network quality of the network system comprises: parameters such as transmission rate, time delay, capacity, connection quantity and the like can be specifically selected and increased according to actual conditions, and the embodiment of the application is not particularly limited.
In the embodiment of the application, the network systems in the first network system set, the second network system set and the third network system set can be modified and increased correspondingly according to actual conditions, and the embodiment of the application is not limited in particular.
The network system is divided according to the data transmission capability of the network system, wherein the network system in the first network system set is SA/NSA, the network system in the second network system set is LTE, 3G, the network system in the third network system set is 2G, and the like, the data transmission rate of NSA/SA is 10 times of that of LTE, namely, the data stream with the same size is transmitted, the time spent by NSA/SA is only a few tenth of that of LTE, and the data transmission rate of LTE is tens of times of TDSCDMA, WCDMA.
In the embodiment of the application, a terminal judges a network system set to which a current network system belongs, when the current network system is in a first network system set, the terminal judges that the current network system is a high-quality network system, at the moment, the terminal determines a Cell transmission sub-stream as a target transmission sub-stream and schedules data to be transmitted preferentially through the Cell sub-stream; when the current network system is in the third network system set, the terminal judges that the current network system is a low-quality network system, at the moment, the terminal determines the Wi-Fi transmission sub-stream as a target transmission sub-stream, and schedules data to be transmitted through the Wi-Fi sub-stream.
In the embodiment of the present application, the at least two transmission sub-streams may include a cell transmission sub-stream and a Wireless-broadband (Wi-Fi) transmission sub-stream, where the number of cell transmission sub-streams is at least one, and the number of Wi-Fi transmission sub-streams is at least one.
Further, the data transmission rate corresponding to the network system in the third network system set is the lowest, and the data transmission process with large data volume cannot be carried, so that when the current network system is in the third network system set, the terminal prohibits the scheduling of the data to be transmitted by the cell transmission sub-stream.
Illustratively, when the network system of the network in which the terminal is currently registered is 2G, the terminal prohibits scheduling data to be transmitted via the Cell substream.
In the embodiment of the application, when the current network system is in the second network system set, the terminal respectively acquires the transmission parameters of the cell transmission sub-stream and the Wi-Fi transmission sub-stream, and determines the target transmission sub-stream from at least two transmission sub-streams according to the transmission parameters of the cell transmission sub-stream and the Wi-Fi transmission sub-stream. Specifically, the terminal compares the transmission parameters of the cell transmission sub-stream with the transmission parameters of the Wi-Fi transmission sub-stream to obtain a comparison result; calculating a parameter difference between a transmission parameter of the cell transmission sub-stream and a transmission parameter of the Wi-Fi transmission sub-stream; and determining a target transmission sub-stream from the at least two transmission sub-streams according to the comparison result and the parameter difference value.
In the embodiment of the present application, the transmission parameters of the transmission sub-stream may be RTT values, parameters related to congestion of the transmission channel, and the like, which may represent transmission characteristics of the transmission sub-stream, and are specifically selected according to practical situations, and the embodiment of the present application is not specifically limited.
In an alternative embodiment, when the current network system is LTE, the terminal obtains the RTT value of the Cell substream and the RTT value of the Wi-Fi substream respectively, then, the terminal compares the RTT value of the Cell substream with the RTT value of the Wi-Fi substream, obtains the RTT difference between the Cell substream and the Wi-Fi substream, and when the RTT value of the Cell substream is smaller than the RTT value of the Wi-Fi substream and the RTT difference between the Cell substream and the Wi-Fi substream is greater than a preset threshold, the terminal determines the Cell substream as a target transmission substream; when the RTT value of the Cell substream is smaller than that of the Wi-Fi substream and the RTT difference value between the Cell substream and the Wi-Fi substream is smaller than a preset threshold value, the terminal determines the Wi-Fi substream as a target transmission substream; when the RTT value of the Cell substream is larger than that of the Wi-Fi substream, the terminal determines the Wi-Fi substream as a target transmission substream.
In another optional embodiment, when the current network system is 3G, the terminal acquires an RTT value of the Wi-Fi substream, compares the RTT value of the Wi-Fi substream with a preset 250ms, and when the RTT value of the Wi-Fi substream is less than 250ms, the terminal speaks the Wi-Fi substream to be determined as a target transmission substream; when the RTT value of the Wi-Fi sub-stream is larger than 250ms, the terminal further compares the RTT value of the Cell sub-stream with the RTT value of the Wi-Fi sub-stream, and obtains the RTT difference value between the Cell sub-stream and the Wi-Fi sub-stream, specifically, when the RTT value of the Cell sub-stream is smaller than the RTT value of the Wi-Fi sub-stream and the RTT difference value between the Cell sub-stream and the Wi-Fi sub-stream is larger than a preset threshold, the terminal determines the Cell sub-stream as a target transmission sub-stream; when the RTT value of the Cell substream is smaller than that of the Wi-Fi substream and the RTT difference value between the Cell substream and the Wi-Fi substream is smaller than a preset threshold value, the terminal determines the Wi-Fi substream as a target transmission substream; when the RTT value of the Cell substream is larger than that of the Wi-Fi substream, the terminal determines the Wi-Fi substream as a target transmission substream.
It should be noted that, the above-mentioned two alternative implementation manners of determining the target transmission substream from the at least two transmission substreams according to RTT transmission parameters of the at least two transmission substreams by the terminal are not limited to the above-mentioned two implementation manners, and other deformation schemes of determining the target transmission substream from the at least two transmission substreams according to transmission parameters of the cell transmission substream and transmission parameters of the Wi-Fi transmission substream belong to the protection scheme of the present application, which is not limited in detail.
In the embodiment of the application, the data to be transmitted is a TCP segment.
In the embodiment of the application, after the terminal determines the target transmission substream, the terminal preferentially schedules the data to be transmitted through the target transmission substream, and when the conditions that the amount of the data to be transmitted in queuing is large, acknowledgement (ACK) related to the TCP segment through the target transmission substream does not exist, and the like exist, the terminal can select other transmission substreams from at least two transmission substreams to take over to schedule the data to be transmitted, thereby ensuring the continuity and timeliness of data scheduling.
As shown in fig. 2, an MPTCP data scheduling policy flowchart of the terminal based on the cellular network system is as follows:
1. the terminal acquires a current network system;
2. the terminal judges whether the current network system is NSA/SA;
3. when the current network system is NSA/SA, the terminal adopts Cell substream to schedule TCP segments preferentially;
4. when the current network system is not NSA/SA, the terminal judges whether the current network system is LTE;
5. when the current network system is LTE, the terminal determines a target transmission substream from the Cell substream and the Wi-Fi substream by using RTT of the Cell substream and RTT of the Wi-Fi substream;
6. when the current network system is not LTE, the terminal judges whether the current network system is 3G;
7. when the current network system is 3G, the terminal determines a target transmission substream from the Cell substream and the Wi-Fi substream by using RTT of the Cell substream and RTT of the Wi-Fi substream;
8. when the current network system is not 3G, the terminal preferentially adopts Wi-Fi substreams to schedule TCP fragments.
It can be understood that the data transmission amount and the data transmission performance corresponding to different network systems are different, and the terminal determines the target transmission substream with the highest data transmission performance from at least two transmission substreams according to the data scheduling strategies corresponding to different current network systems, so that the accuracy of route selection can be improved; at this time, when data is scheduled via the target transport substream, higher data transmission performance can improve the rate of data scheduling.
