Communication infrastructure is a vital part of common tools for ATCO. Transmission and exchange of data allows to improve ATM quality. Dedicated communication (LAN) infrastructure for ATM purposes is needed for providing appropriate level of quality. Number of data in ATM is still growing from year to year. Concept of shared LAN infrastructure was sufficient few years ago, but still growing amount of data, as well as more and more demanding requirements for data transmission faced us in front of necessity of splitting data transmission infrastructure on few independent parts, where the most important will be SWIM-ready ATM operational part. Such upgrade and development for communication infrastructure is strongly related with increasing capabilities, which are required for providing appropriate security level. It will also allow to improve management of information flow, including especially integration existing legacy information solutions with SWIM environment. Such upgrade allow also to achieve required QoS level, taking into account requirements related with Blue Profile and its technical consequences. It is also strongly related with growing amount of information, as a consequence of still more intensive cooperation between identified on national level stakeholders. The project supports: AF5 in developing information infrastructure and AF 5.2.1 in developing of Stakeholder Internet Protocol Compliance. Cooperation with Military Stakeholder in this particular are allow to increase project efficiency and multiply project benefits.
