Embodiment Construction

[0054] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the application. Obviously, the described embodiment is only It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0055] After research, the inventor found that in order to realize the measurement of network delay with a small measurement overhead, it is necessary to ignore the network delay between the network device end and the DNS server, and use a relatively small amount of network delay between DNS servers to represent the relative Network delay between a large number of ...

Abstract

The embodiment of the invention discloses a method for measuring network time delay. The method comprises the steps of looking up available basic facilities for network time delay measurement in a network and establishing network coordinates for the available basic facilities and all network device terminals to be measured, determining available basic facilities closest to the network device terminals based on the network coordinates of the available basic facilities and the network device terminals to be measured, measuring network time delay between any two available basic facilities by transmitting a message for measurement between the two available basic facilities, and determining that the network time delay between the available basic facilities closest to any two network device terminals to be measured is the network time delay between the two network device terminals to be measured. By means of the method for measuring the network time delay, accurate network time delay measurement can be achieved under the condition of smaller network load. In addition, the embodiment of the invention further discloses a device for measuring network time delay.

Description

technical field [0001] The invention relates to the field of network performance testing, in particular to a method and equipment for measuring network delay. Background technique [0002] In the Internet, it takes a certain amount of time for data to be transmitted from one network device to another, and the data transmission time is the network delay between the two network devices. Network delay can reflect the performance of data transmission between network devices and is one of the important references for network performance. Therefore, in many practical application scenarios, it is necessary to measure the network delay, so as to configure the network according to the network delay. For example, for a Content Delivery Network (CDN for short), the network delay between the client and the server is an important factor in the performance of the CDN network. Therefore, in an Internet Content Provider (ICP for short), ) When selecting a CDN, it is necessary to measure t...
