Sustaining a Vertically Disintegrated Network through a Bearer Service Market

Based upon the Internet perspective, this chapter will attempt to clarify and revise several ideas about the separation between infrastructure facilities and service offerings in digital communications networks. The key notions that we will focus on in this paper are: i) the bearer service as a technology-independent interface which exports blind network functionality to applications development; ii) the sustainability of an independent market for bearer service and the organizational consequences associated with such a market.
