Abstract
Behavior of current communication protocols as well as current and future
networked applications is of fundamental importance for technical and
commercial success of Mobile Internet. The forthcoming wireless Wide-Area
Networks, such as GPRS and UMTS, are quite complex and network operators
have a large set of parameters to tune the transfer performance of these
networks. In this situation it is of great value to be able to execute
practical experiments. The Seawind emulation software introduced in this
paper enables measurements of protocol implementations in modeled
networking environments. The Seawind software provides a rich set of ways
to define transfer characteristics including delays and errors. The
software has also means to conduct large sets of experiments in an
automatic fashion. In addition, tools of analyzing measurement data has
been integrated into the Seawind software.
