Measurement one way delay method and equipment thereof, and communication system

Abstract

The embodiment of the invention provides a measurement delay method and equipment thereof, and a communication system. The method comprises the following steps that: second equipment receives at least two messages, which are sent by first equipment in a preset interval of time; a reference message is determined between the received at least two messages, wherein the one way delay of the reference message is a delay radix; relative delay of at least one non-reference message is calculated, wherein the non-reference message is the other message except the reference message between the at least two messages; and one way delay of the at least non-reference message is obtained according to the delay radix and the relative delay of the at least non-reference message.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication systems, and more specifically, to a method, device and communication system for measuring one-way delay. Background technique [0002] As the network structure of the Internet is becoming more and more complex, and the changes are random and diverse, coupled with the continuous emergence of new information transmission technologies, new network environments, and new network services, it has become an important task to master the laws of Internet operation and provide a reliable theoretical basis for the improvement of network technology. an important issue for development. Through the measurement of the end-to-end delay, the basic characteristics of the current network can be analyzed, and a reliable basis can be provided for the improvement of network protocols and control mechanisms. [0003] At present, the delay measurement methods mainly include the method based on the...

AI Technical Summary

Problems solved by technology

[0012] Although 2DM does not require clock synchronization between the source MEP and the target MEP, it calculates the two-way delay and cannot accurately calculate the one-way delay

In addition, 2DM frequently sends messages for delay measurement, which will occupy too many network resources

[0013] In addition, the delay measurement method based on MPLS-TP is similar to the delay measurement method based on the Y.1731 standard. Therefore, the delay measurement method based on MPLS-TP also has the above disadvantages
