While the development and operation of internet infrastructures during the early days of the internet were primarily driven by public institutions, this sector is now largely dominated by private companies. This book describes services, value creation processes, and competitive strategies for providing data transport on the internet from a business perspective. It discusses internet access services for connecting end users, transit services for data exchange between network operators, services for capacity provision in the core network, and services for the distribution of digital content and applications. By presenting the sub-markets that address data transport on the internet, the reader is offered a comprehensive insight into the internet economy, without requiring a deep technical understanding.
