Abstract

The embodiment of the present invention provides a UDP data packet reliable transmission method, system, computer equipment and storage medium. The method includes: sending a connection request to a receiving client, obtaining a connection confirmation signal returned by the receiving client, marking the connection status of the connection initiator as connected; sending a buffer size synchronization request to the receiving client, and presetting the buffer size Proportional data is sent to the receiving client, and subsequent data is sent according to the receiving confirmation signal of the receiving client; a disconnection notification is sent to the receiving client, and the disconnection notification includes three disconnected data packet, the connection ends. During the connection process, the connection initiator establishes the connection with two handshakes. When sending data, it calculates the number of idle buffers of the receiver to ensure that the receiver can completely receive the data packets, which can solve the problem of packet loss during the transmission of UDP packets. and out-of-order problems.

Description

technical field [0001] The invention relates to the technical field of network security, and in particular, to a method, system, computer equipment and storage medium for reliable transmission of UDP data packets. Background technique [0002] In the current technology, there are two representations of IP addresses, namely IPv4 (Internet Protocol Version 4) and IPv6 (Internet Protocol Version 6). The length of an IPv6 address is 128 bits, and there are 2^128 IP addresses in total, which theoretically cannot be used up, but the IPv6 protocol is not yet popular. At present, most of the WANs use IPv4 addresses. The length of IPv4 addresses is 32 bits, and there are 2^32 IP addresses in total. After removing some reserved IP addresses, IPv4 addresses can no longer meet the needs, and it is difficult to apply for a public IP address. address. In order to solve the problem of the shortage of IPv4 addresses, NAT (Network AddressTranslation) appeared, that is, the network address ...
