  IAB COVID-19 Workshop: Interconnection Changes in the United States
            draft-feamster-livingood-iab-covid19-workshop-01

Abstract

   During the early weeks and months of the COVID-19 pandemic,
   significant changes to Internet usage occurred as a result of a
   sudden global shift to people working, studying and quarantining at
   home.  One aspect that this affected was interconnection between
   networks, which this paper studies.  This paper explores some of the
   effects of these changes on Internet interconnection points, in terms
   of utilization, traffic ratios, and other performance characteristics
   such as latency.

1.  Introduction

   During the early weeks and months of the COVID-19 pandemic
   [WHO-Declaration], significant changes to Internet usage occurred as
   a result of a sudden global shift to people working, studying and
   quarantining at home.  One aspect that this affected was
   interconnection between networks, which this paper studies.

   In 2016, the Interconnection Measurement Project [Tinker-Blog] was
   launched.  The IMP platform initially collected interconnection-
   related data from seven U.S.-based cable-based Internet Service
   Providers (ISPs) and an [ArXiv-Paper] shared some of the details and
   findings.  The initial focus of the project was to explore
   utilization characteristics of interconnect links during a period of
   time when video traffic was steadily increasing.  The project
   concluded that there was ample aggregate capacity on interconnect
   links between ISPs and peers (including content providers), and that
   ISPs continually added capacity to their interconnects to keep pace
   with the growth in traffic.

   This IAB paper looks specifically at the long-term interconnection
   data from one of those ISPs, Comcast.  We examine the long-term pre-
   COVID-19 trend as well as what occurred as COVID-19 impacted the
   Internet from February 2020 through August 2020.  We also include
