Embodiment 1

[0024] The existing technology uses the NTP protocol for time synchronization, and the PTP server is a better choice for time synchronization. It is a master-slave synchronization system that uses master-slave clocks to encode time information. The symmetry of the network and the delay measurement technology realize the synchronization of the master-slave time, and the accuracy can reach the sub-microsecond level, which is in line with the actual setting. In this embodiment, the PTP server is used for time synchronization. When running for the first time, the evaluation party sets up PTP servers in all evaluation sites, completes the configuration and keeps running to ensure the uniform time of PTP servers in all places.

[0025] The evaluation party obtains the terminal through the mainstream APP market and the official website of the service entity, and installs it in a pure test device of the same specification. In this embodiment, the test device is a mobile phone.

Embodiment 2

[0045] Generally speaking, the method of the present invention involves three parties: the data sender, the evaluation party and the evaluated party. Correspondingly, there are two stages: software and hardware preparation stage and evaluation implementation stage.

[0046] First of all, in the software and hardware preparation stage, the evaluation party should install and configure interoperable PTP servers in all its test locations and conduct tests to ensure that the accuracy of time synchronization is less than 1ms. At the same time, all test mobile phones should be connected to the test server whose time has been synchronized with the PTP server through the adb terminal (the operating terminal of the mobile phone, which needs to be installed in the evaluation server in advance) to synchronize the time of the mobile phone. The time of the mobile phone and the test server are all consistent. After obtaining the terminal through the mainstream APP market and the official w...

Abstract

The present invention relates to the technical field of data transmission evaluation, in particular to a data transmission delay evaluation method and device, the sender server sends out data, and the data is received by the test client after being processed by the evaluation server. When the terminal receives new data, it calls the CPU for processing for the GPU to render on the screen, and marks the time when the rendering occurs as the delivery time stamp. After all the data packets are transmitted, mark each test client according to each data information The delivery timestamps of the terminals are sorted from early to late. Compared with the prior art, the present invention has the advantages that the evaluation result is more accurate, and through the reasonable design of the evaluation method and the reasonable selection and use of the evaluation equipment, the graded evaluation of the data transmission speed can be effectively realized, especially suitable for For the evaluation of securities market speed, it can evaluate the market transmission speed of different securities companies and different servers, and perform classification and sorting.

Description

technical field [0001] The present invention relates to the technical field of data transmission evaluation, in particular to a data transmission delay evaluation method and device. Background technique [0002] In today's securities industry, a hundred flowers are blooming, and there are securities firms of various sizes in the market that provide market services for investors all over the country. Market information reflects changes in the market and affects the behavior of investors. Therefore, both brokers and investors are constantly pursuing a faster update speed. However, at present, there is no professional and authoritative evaluation method that can grade and evaluate the market transmission rate of large and small brokerages, thus resulting in a lack of comparison of the most intuitive indicator that investors care about. [0003] The Shanghai Stock Exchange has launched Level-2 market quotations since 2006, providing more comprehensive and high-speed market ser...
