Research on universal network performance testing model

Network performance testing is one of the key components in optimizing network resource configuration and improving network performance. Existing performance testing tools usually focus on single performance parameters, and lack of the ability to satisfy integrated testing demands of network administrators. In this paper, a universal network performance testing model based on policy scheduling is proposed, which integrates many kinds of performance testing tools into a single system, and provides a uniform testing interface to network administrators. Universal Probe (UP) is the key component of such a model, thus a detailed study is given on UP, which includes UP architecture, policy-based UP cooperation, mobility, and UP deployment under resource constraints. At last, a practical Network Monitor and Measurement System that designed based on the discussed concepts is presented.
