International IP network traffic 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 vetween Japan and the PACCOM network. This traffic measurement allows and examination of the current stats of international information flow. Such analyses are a first, and essential, step toward a better understanding of the type, quantity, and breadth the of international traffic flow. They can provide not only confirmation 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.
