User datagram protocol UDP port multiplexing method, device and equipment

Abstract

The embodiment of the invention provides a multiplexing method, device and equipment for a user datagram protocol UDP port. The method comprises the following steps: acquiring a stream taking data packet monitored by a first socket of monitoring equipment; analyzing the stream fetching data packet to obtain address information of a client requesting stream fetching; creating a second socket and generating a mapping relationship between the address information of the client and the second socket, wherein the second socket and the first socket are bound to the same UDP port of the monitoring device; and selecting a second socket having a mapping relationship with the address information of the client to transmit the monitoring data to the client. Therefore, the data can be transmitted according to the source end corresponding to the data without considering which UDP socket the data is received, so the cross-platform difference of the UDP sockets can be eliminated, and the cross-platformmultiplexing of the UDP port of the equipment is realized.

Description

technical field [0001] This document relates to the field of communication technology, and in particular to a method, device and equipment for multiplexing UDP ports of User Datagram Protocol. Background technique [0002] The User Datagram Protocol (UDP) belongs to the transport layer protocol in the Open System Interconnect (OSI) reference model, and is used to provide connectionless unreliable message transmission services. [0003] In traditional UDP protocol-based data transmission business scenarios, there may be multiple servers or / or clients interacting with the same device at the same time, such as figure 1 As shown, the server and client A interact with the device at the same time, or, client A and client B may interact with the device at the same time. In response to this situation, there are currently two common solutions as follows. One is that the device opens a UDP port for external interaction for each server / client data interaction, but this solution occupi...

Problems solved by technology

In response to this situation, there are currently two common solutions as follows. One is that the device opens a UDP port for external interaction for each server / client data interaction, but this solution occupies a lot of port resources on the device; Moreover, if there are many devices under the same network, the UDP port resources of the router will be consumed a lot

The other is that the device uses the same UDP port to interact with multiple servers / clients. However, due to the differences of various operating systems, the UDP port multiplexing implementation logic of the device cannot support cross-platform, and can only be used on specific platforms. use
