An analysis of international academic research network traffic between Japan and other nations

International IP network tra c is evaluated for applications utilizing the TCP transport protocol. This evaluation is based on an analysis study performed in January 1992 across an infrastructural connection between Japan and the PACCOM network. This tra c measurement allows an examination of the current status of international information ow. Such analyses are a rst, and essential, step toward a better understanding of the type, quantity, and breadth of international tra c ow. They can provide not only con rmation or refutation of intuitions and existing paradigms related to data exchanges, but also a fundamental framework upon which to base future network management, planning and design.
