MPQUIC data packet rapid transmission method and system based on priority level queue

Abstract

The invention provides an MPQUIC data packet rapid transmission method and system based on a priority level queue, and the method comprises the steps: 1, enabling a transmitting end application program to generate a to-be-transmitted MPQUIC data packet, and putting the data packet into a scheduling queue corresponding to the priority level of the data packet; 2, transmitting the data packet to a receiving end cache region according to a scheduling strategy corresponding to a scheduling queue in which the data packet is located; 3, enabling the receiving end cache region to arrange the data packets in sequence to obtain to-be-operated data and the size of an out-of-order queue, and enabling a receiving end application program to extract the to-be-operated data to complete services corresponding to the data packets to obtain service quality; 4, updating and optimizing the scheduling strategy according to the size of the out-of-order queue and / or the service quality. Compared with a traditional single scheduling mode, the method has the advantages that a data packet scheduling algorithm can be combined with an actual application scene and user requirements, and subsequent integration of the data packet scheduling algorithm is facilitated.

Description

technical field [0001] The invention relates to the field of computer network transmission control, and in particular to a method and system for fast transmission of MPQUIC data packets based on priority hierarchical queues. Background technique [0002] QUIC (Quick UDP Internet Connections) is a low-latency Internet transmission protocol based on the UDP (User Datagram Protocol) protocol. Since the Internet Engineering Task Force (IETF) proposed a standardization draft, QUIC has received extensive attention from the industry. This also means that QUIC has started its standardization process and has become a new generation of application layer transport layer protocol. Internet companies dominated by Google hope to use this protocol to replace the TCP protocol to speed up video traffic and web page transmission. Recently, the HTTP and QUIC working group of the IETF officially renamed HTTP (HTTP over QUIC) based on the QUIC protocol to HTTP / 3 as the next-generation specifica...

Problems solved by technology

[0006]The aforementioned existing algorithms have all proposed scheduling methods with better performance in theory, but they all use the basic information of the path to make forward-predicted scheduling results, and both Corresponding to special application scenarios

However, the existing mobile application scenarios are different and diversified. The data importance of different applications and the impact on user experience are not the same. At this time, the scheduling algorithm for special scenarios cannot make full use of multi-path bandwidth aggregation. effect, and even serious headof line (HoL) problems, unable to achieve high quality of service

Using the redundant sending mechanism can ensure the correctness and reliability of data, and multiple paths are actually decoupled when sending redundantly, which can alleviate the HoL problem, but different application scenarios have different requirements for redundant sending. There is still no comprehensive solution to this problem
