The field of Internet monitoring is facing enormous challenges. Being unable to explain or fully understand the phenomenon resulting from network changes limits the ability to continue scaling the Internet and undermine attempts to improve its robustness. Several research efforts are tackling this problem, notably Internet Surveyor project, NLANR AMP project, and so on. Although all these works have proved their applicability in many cases, there are still a number of problems to be considered. This paper addresses and discusses a model for network performance monitoring, which is adopted in the management of China Educational & Research Network, a national wide information network of China. Current state\|of\|the\|art of the Internet performance monitoring is introduced first, which greatly helps to formulate the set of goals and requirements that a large\|scale performance monitoring must meet. Then an architecture model solution to systematize the implementation of Internet monitoring is given. Some key points about how to achieve the model are discussed together with examples of the applications of the model in CERNET's performance monitoring. Finally, it is deduced that the model has great advantages and is suitable to direct the monitoring works of Internet.
