The author believes that Mashiwentong did not equal the Tuituo conjunction to the Biandou conjunction .

The thesis standardized the extension information and the extension knowledge,that is,basing on the information and knowledge,the thesis extended the mutative information and knowledge,and nailed down the conceptions of extension data mining and extension reasoning.

Extension proposition and extension reasoning are discussed.

It gives the models and concerned concepts of extension reasoning,and discusses realizing process of reasoning algorithm.

Self adaptive network topology inference algorithm in tomography

Network topology inference based on round trip time

In order to reduce the limits in topology inference of one parameter,a multiple parameters network topology inference method,combining end to end delay and loss,was proposed.

A topology inference algorithm based on dynamically adapted link loss-ratio;

Research on topology inference algorithm of improved sandwich probing mechanism;

This paper introduces the achievements of Internet end to end performance measurement technologies,including metric induced topology inference,delay inference,loss probability inference and bandwidth measurement.

Network topology inference is one of the basic functions of a network management system, and the AS-level topology inference is its focus and difficult point.
