Problems solved by technology

[0004] The existing measurement method can only obtain the RTT value between the monitoring point and the receiving end, and cannot actually measure the RTT value between the sending end and the receiving end. If the monitoring point is far from the sending end, the value obtained by the above RTT measurement method large error

Abstract

The invention provides a network loopback time measurement device, system and method. The method comprises the following steps: establishing a real-time communication model based on Simulink Real-TimeUDP; establishing an Ethernet for the client host and the receiving end server; and establishing a Simulink Real-Time round trip time RTT measurement model in a Matlab development environment on a host, wherein a numerical value of an 'output display' module in the model is a round trip time delay value of an actual network. By utilizing the UDP communication between the Simulink host and the server, the real-time response of the controller based on the UDP communication can be quickly and accurately evaluated, and the network loopback time measurement device, system and method are suitable for network response tests of various servers.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a network loopback time measuring device, system and method. Background technique [0002] The round-trip time (Round-Trip Time, RTT) is an important performance indicator in network transmission, which means the time elapsed from sending a packet from the source end to receiving the confirmation ACK packet from the communication end. RTT is determined by three parts: link Propagation time, processing time at the sending end and receiving end, and queuing and processing time in the cache of intermediate network devices, RTT is an important parameter that affects network transmission performance and characterizes network operating conditions. [0003] MathWorks Simulink Real-Time provides the ability to connect to the specific target computer hardware of the physical system, build, test and run real-time applications through Simulink models, and provide a complete e...
