Abstract: Current analysis on network behavior bypasses the impact that commercial features of autonomous systems have on the network structure. This paper explores the peering behavior of distinct types of autonomous systems from the perspective of revenues and costs. The distribution of interdomain traffic volumes and the peering preferences of autonomous systems are analyzed through the data samples in PeeringDB, with the presence of strong correlations between peering policies and interdomain traffic volumes of NSP and access providers, while there is no such correlation for content providers, which mainly adopts policy of open peering. It illuminates the motivation based on the properties of these service providers under commercial circumstance, and presents autonomous system as an ecosystem, in which network structure, interdomain traffic and revenues are mutually affected.

Key words: autonomous system, ecosystem, interdomain traffic, peering connection, revenues
