Integration of VSAT networks into user network environment

The integration of VSAT networks into user environments has some specific impacts caused by the long path delay and by system immanent influences of the transmission path. There are particular demands with the integration into the various protocol environments. The VAST network considered here is about advanced business communication via satellite (ABCS). ABCS is a satellite-based wide area network (WAN) for the networking of local area networks (LANs) and frame relay access devices (FRADs). ABCS is a fully meshed network structure serving up to 30 stations distributed throughout Europe. It offers a transfer rate of up to 4 Mbps with a channel error rate of better than 10^-7. The satellite channel is accessed via the demand-oriented TDMA procedure (time division multiple access) which is communally planned by all stations. When integrating such VSATs into user network environments, the tasks to be solved are the integration of the interface, protocols and the embedding into a standardised network management
