Abstract

The paper presents an analysis of short- and long-term changes in the QoS of intercontinental connections. First we will show that despite fast and numerous advances in physical layer, link layer, router capacity and new telecommunication cables deployment, QoS measures are hardly progressing in long-term (years) perspective. Transatlantic (North America – Europe) connections will be thoroughly analyzed. Next we will show that due to submarine cable breakages temporary network performance is unpredictable. It may be much poorer than average and sometimes drops below the acceptable level – case study is provided. Even if the links are fully operational, due to the rerouting the QoS may deteriorate in the case of cable fault in another part of the World. The research is based mainly on data taken from IEPM (Internet End-to-end Performance Measurement) database.
