An end-to-end delay measurement and optimization method based on tdma data link heterogeneous network

Abstract

The invention discloses a method for measuring and optimizing end-to-end delay based on a TDMA (time division multiple address) data link heterogeneous network. The method comprises the steps of calculating the transmission bit error rate of each link, establishing and superposing single data link network topology matrixes of each type of the data links to acquire a network topology matrix of the data link heterogeneous network, calculating the minimum hop count of end-to-end data transmission and recording all relay nodes, measuring the end-to-end delay generated by the data transmission, and optimizing the data link heterogeneous network. The method disclosed by the invention gives full consideration to influences imposed on the end-to-end delay of the TDMA data link heterogeneous network by channels, links and networking in the data transmission process, thereby not only being capable of acquiring more accurate end-to-end delay, but also reducing the design cost of the data link heterogeneous network, and optimizing the network performance in the design stage.

Description

technical field [0001] The invention relates to a method for measuring time delay generated by information transmission in a communication network, more particularly, a method for measuring and optimizing end-to-end time delay based on a TDMA data link heterogeneous network. Background technique [0002] Data link is a commonly used information interaction system in communication network. In order to reduce transmission conflicts between nodes, the data link usually adopts a Time Division Multiple Access (TDMA) access system to realize multipoint-to-multipoint networking data transmission. At present, various types of data links have been developed at home and abroad, but the emergence of new data links does not mean that the old data links will be replaced immediately. They are different in scope of use, transmission distance and transmission speed, etc. One data link can be used instead of another data link. Therefore, it is an inevitable trend in the development of data...

Problems solved by technology

However, most calculation methods study the end-to-end delay of data transmission above the link layer, ignoring other factors such as channels. At present, there is no calculation method that can simultaneously consider the channel, link, and networking effects on data link heterogeneous networks. The effect of terminal delay
