Interconnection Economics of All-IP Networks

This paper is an exploratory study on the interconnection economics of All-IP networks. To understand the economics of the yet-to-be-realized All-IP networks, this paper begins with discussing three important features of current IP networks: packet switching, receiver benefit, and two-sidedness. It then develops simple models of interconnection for basic fixed fee settlements and for session-based charges. The analysis shows that interconnection settlements depend on network size, market competitiveness, direct and cross network externalities, and costs. Some policy issues are also briefly discussed.
