End-to-End (E2E) packet delivery in the Internet is achieved through a system of interconnections between heterogeneous entities called Autonomous Systems (ASes). The initial pattern of AS interconnection in the Internet was relatively simple, involving mainly ISPs with a balanced mixture of...

The Domain Name System (DNS) is critical infrastructure for the Internet. The growth in size and complexity of the DNS, together with changes in its governance and operational practices, have raised numerous challenges. Herein, we provide a qualitative and empirical overview of DNS ecosystem...

This paper represents a synthesis and extension of earlier work, applying the Lehr & Sicker (2018a,b) regulatory approach to the layered platform model of Claffy & Clark.3 Today's Internet ecosystem is comprised of multiple digital network platforms organized into a multi-layer architecture....

This paper uses a novel dataset from multiple ISPs to characterize important trends in broadband traffic growth, develop a better understanding of usage-related costs, and consider the implications of this growth for both network operators (e.g. subscription plans and traffic management...

This paper discusses the evolution of the congestion controls that govern all Internet traffic. In particular we chronicle and discuss the implications of the fact that the most significant "congestion signals" are increasingly coming from network operators, not the TCP stack. Providers now...

In days past, Internet Service Providers (ISPs) relied on two basic types of contracts for exchanging traffic (peering and transit) and ISP interconnection was not regulated. As we explained in (Faratin, Clark et al. 2007), the world of Internet interconnection is no longer so simple. The...

With broadband availability now approaching universal service in the United States, the focus on broadband metrics is shifting toward the assessment of broadband performance. The initial focus has been on the measurement and reporting of the speeds achieved by broadband services. As we develop...

In previous papers, Lehr and Sicker (2018a,b) argued that the changing character of our telecommunications infrastructure called for a new regulatory approach, with a new Communications Act to define the duties and authorities of a reconceptualized FCC (what we call newFCC in this paper)....

This paper addresses the question of what should be meant by the phrase the Internet, or equivalently, the public Internet. Since its origins in the 1960s, the Internet has changed significantly in terms of the networks and technologies, services that are supported, and industry players who...

Interconnection links connecting access providers to their peers, transit providers and major content providers are a potential point of discriminatory treatment and impairment of user experience. In the U.S., the FCC has asserted regulatory authority over those links, although they have...
