In this paper we will give the statistical characteristics and general principles of an optimal structure of the Inteet, which is a scale-free network. Since the purpose of the Inteet is to allow fast and easy communication,the average path length is used to measure the performance of the network, and the number of edges of the network is used as a metric of its cost. Based on this, the goal of this Inteet optimization problem is to obtain the highest performance with the lowest cast. A multi goal optimization problem is proposed to model this problem. By using two empirical formulas of
