Problems solved by technology

[0004] However, end-to-end measurement also has its limitations. Because end-to-end measurement needs to install measurement software on a large number of hosts, that is, it needs to deploy a large number of measurement nodes to achieve comprehensive measurement of Internet IP QoS information, which makes the measurement cost huge. increase in magnitude

Abstract

An embodiment of the invention discloses a method and device for predicting QoS information of IP address paths. The method and device for predicting QoS information of IP address paths are used for predicting QoS information of the paths through a small amount of measuring nodes and reducing measuring cost. The method comprises the steps of determining a third node nearest to a first node in a backbone network and a fourth node nearest to a second node; obtaining a first IP address path from the first node to the third node, a second IP address path from the second node to the fourth node and a third IP address path from the third node to the fourth node; obtaining QoS information of the first IP address path and QoS information of the second IP address path through a QoS measuring tool; and calculating QoS information of an IP address path the first node to the second node. An embodiment of the invention further provides the device for predicting QoS information. The method and the device can reduce measuring cost.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for predicting QoS information of paths between IP address pairs. Background technique [0002] With the rapid development of the Internet and the great enrichment of network services, the Internet has become a public information transmission platform that carries various services and serves various user groups. However, due to the inherent connectionless nature of the interconnection protocol between networks (English: Internet Protocol, IP for short) and the "best effort" service principle of traditional IP networks, the traditional Internet cannot provide users with effective quality of service guarantees, nor can it Realize effective monitoring and management of network resources. This situation has seriously hindered the development of the Internet in depth. In the past ten years, experts and scholars at home and abroad have carried out unremitti...
