Problems solved by technology

[0003] In order to meet the needs of VPN, most of the programs are based on IP tunneling technology, for example: currently the most used is the Secure Sockets Layer (Secure Sockets Layer, SSL) VPN, which converts the original IP message (or inner layer IP message), encapsulating Transmission Control Protocol (Transmission Control Protocol, TCP) + Transport Layer Security Protocol (Transport Layer Security, TLS) (or SSL), but this kind of transport layer protocol based on TCP as IP tunnel, its packet loss Flaws in recovery will reduce the transmission rate, and TCP congestion control also has problems such as imprecise granularity, which often leads to unstable VPNs

Abstract

The embodiment of the invention discloses a client, a message sending method, a message receiving method, equipment and a storage medium. The client comprises a TUN virtual network device which is used for reading or writing an original internet protocol (IP) message; and the QUIC tunnel processing module is used for encapsulating or de-encapsulating the original IP message by using a rapid UDP (User Datagram Protocol) network connection QUIC protocol, and sending or receiving the encapsulated original IP message. According to the technical scheme provided by the embodiment of the invention, the original IP message is packaged and transmitted by using the QUIC protocol, so that the rapid and stable transmission of the original IP message is realized.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a client, a message sending and receiving method, device, and storage medium. Background technique [0002] The function of a virtual private network (Virtual Private Network, VPN) is to establish a private network on a public network for encrypted communication. The VPN gateway realizes remote access by encrypting the data packet and converting the destination address of the data packet. Internet Protocol (Internet Protocol, IP) tunneling technology is a process of encapsulating a network layer protocol into another protocol for transmission across the network. The header contains the original sender and final destination, also called inner IP packet) encapsulated in the data payload of another data packet (called encapsulated IP packet, also called outer IP) for transmission. [0003] In order to meet the needs of VPN, most of the program...
