Problems solved by technology

For widely deployed mobile Web services, users may come from different regions, use different Internet Service Providers (Internet Service Providers, ISPs) and home devices, and devices in these networks may have user datagram protocol (User Datagram Protocol, UDP) have different preferences and thus will affect the performance of QUIC
For example, since UDP traffic is more likely to be used as malicious attack traffic, an ISP gateway or home router may randomly drop UDP packets, rate limit, or even block UDP traffic
[0007] (3) Limited resources on mobile devices
On the one hand, the packet-level measurement may cause heavy overhead due to querying the statistics of the network stack, and the packet-level protocol exchange will also cause the consistency overhead of the transport layer
On the other hand, sparse granular switching (e.g., user level) may lead to suboptimal performance due to the spatial heterogeneity of mobile users

example 1

[0081] In this example, the matrix distance between the first performance matrix and the second performance matrix is ​​calculated, and it is judged whether the matrix distance is less than the preset threshold. If it is not less than the preset threshold, it indicates that the performance of the mobile terminal is degraded, so that the mobile terminal is connected to the Web The first communication protocol is replaced with the preset third communication protocol.

example 2

[0083] In this example, the second performance matrix is ​​input into the preset protocol classification model, the fourth communication protocol corresponding to the second performance matrix is ​​obtained, and it is judged whether the fourth communication protocol is the same as the first communication protocol. The communication protocol controls the mobile terminal to connect to the Web. In this embodiment, the training logic of the preset protocol classification model may be consistent with the training logic of the foregoing protocol classifier, which will not be repeated here.

[0084] To sum up, the method for selecting an adaptive transport protocol for mobile Web services according to the embodiment of the present invention can measure the network status of the mobile user and switch the transport protocol when necessary. By adaptively switching transport protocols, mobile users can thus benefit from both protocols and have a better experience when using mobile Web s...

Abstract

The present invention proposes a method and device for selecting an adaptive transmission protocol for mobile Web services, wherein the method includes: responding to the ath to a+Nth Web connection requests of the mobile terminal, and obtaining the information corresponding to each Web connection request Multiple Web connection parameters, and determine the Web connection feature group corresponding to multiple Web connection parameters, wherein, a is a natural number greater than or equal to 1, and N is a natural number greater than 1; N web connection feature groups corresponding to the web connection request, generate the first web connection feature matrix according to the N web connection feature groups; input the first web connection feature matrix into the preset protocol classifier, and obtain the web connection request with the mobile terminal The corresponding first communication protocol: controlling the mobile terminal to connect to the Web according to the first communication protocol. Thus, the adaptive selection of the communication protocol between the mobile terminal and the Web is realized, and the performance of the mobile terminal and the occupancy rate of the memory are taken into consideration.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and device for selecting an adaptive transmission protocol for mobile Web services. Background technique [0002] With the development of Internet technology, a variety of communication protocols have emerged, such as the low-latency Internet Transmission Protocol (Quick UDP Internet Connection, QUIC) and Transmission Control Protocol (Transmission Control Protocol, TCP), and various communication protocols have their own advantages and disadvantages. , how to choose becomes a need. [0003] Taking TCP and QUIC as examples, after the QUIC transport protocol was proposed, a large number of measurement studies have shown that there is a performance difference between TCP and QUIC. The key factors affecting the performance difference between using TCP and QUIC mainly include: (1) Network conditions. On slow networks (high packet loss and low bandwidth), the s...
