Measurement method of large-scale network performance measurement system for ip network

Abstract

The invention relates to a large-scale network performance measuring system and method for an IP network. The large-scale network performance measuring system consists of a server and a plurality of network probes, wherein the server consists of a server and a client side and is positioned in a core network, the plurality of network probes are positioned in a measured network, the server is a computer or server which has a massive network data processing capability and is used for generating a measuring task, interacting with the network probes, issuing the measuring task and acquiring measuring results as well as collecting and presenting the measuring results uploaded by the network probes; and the network probes are embedded equipment or computers which are distributed in a clustering manner and are used for receiving and executing the measuring tasks of the server, mainly executing active network measurement and reporting the measuring results. The large-scale network performance measuring system has the capabilities of submitting the measuring results through NAT (Network Address Translation) and acquiring the next measuring task; and the large-scale network performance measuring system has a little influence on the firewall strategy. Besides, the large-scale network performance measuring system has strong real-time property of measuring data, assurance of service quality, large measurement range, capability of realizing measurement among networks, flexible and variable measurement topology, large system capacity, large expandability and favorable popularization prospect.

Description

technical field [0001] The present invention relates to a measurement method of a large-scale network performance measurement system, and more specifically, to a measurement method of a large-scale network performance measurement system used for active measurement of IP networks, which is used to solve the problems caused by firewalls in existing IP networks. The invention belongs to the technical field of data communication, such as small measurement range, single measurement topology, poor real-time performance and poor expansibility caused by network address translation (NAT) and network address translation (NAT). Background technique [0002] Since the birth of the Internet, the measurement technology of network performance has also been produced. For more than 40 years, people have been constantly researching how to measure network performance and various new methods of measuring network to adapt to the rapid development and expansion of the Internet. During this perio...

Problems solved by technology

[0011] (1) The configuration is complicated. Since the existing systems are mostly research systems, the main users are scientific researchers, and the measurement equipment used is relatively special. Most of the networks where they are located need to be specially adjusted, which is not easy to operate

[0012] (2) The NAT gateway cannot be traversed, and the measurement topology is limited

Since the existing measurement methods have not considered the role of the NAT gateway, the existing mechanism cannot cross the NAT gateway for effective communication

Make it very difficult to measure the intranet

[0013] (3) The cost is too high to be commercially available

Because the existing measurement system is mainly based on the server as the measurement device, the cost is too high

It is difficult to promote in reality or the scale is limited by cost and cannot form large-scale measurement
