In this paper, we assume the attributes of entities in the social network, and we observe the process of diffusion when new Internet application services are introduced, based on the relevant theory. At the conclusion of computational experiments, ASPs that have more latency sensitivity and broader bandwidth services have displayed a higher willingness to pay (WTP) for high-priority Internet services. The implication is that an ISP has incentives to discriminate or impose additional fees against those application services that require greater bandwidth and are more latency sensitive. This result supports the assertion of network neutrality proponents, and the network neutrality regulation is necessary even when we consider the diffusion of applications.
