Abstract
The paper presents the studies of traffic management in the satellite ATM bridge based on RACE II RACE project - CATALYST R2074. The project aims to develop satellite ATM bridge that can support the future B-ISDN services for satellite communications. An ATM bridge can interconnect the ATM network and the existing networks as well as DQDB, FDDI, Ethernet networks. The current interfaces have different bit rates, thus the need to control traffic and manage the resources on the bridge to prevent overload and preserve the quality of the services on the satellite. The satellite ATM bridge will be used in the initial interconnections of B-ISDN islands and the development of B-ISDN for mobile telecommunications and direct broadcast services.
