Abstract

Described is a transmission system (10) comprising a gateway (14) for interconnecting first and second networks (12,16). The gateway (14) comprises first and second quality of service translation means (20,24) and interconnection means (22) for interconnecting the first and second quality of service translation means (20,24). The first quality of service translation means (20) are arranged for receiving input data (19) having an associated input quality of service from the first network (12) and for translating the input data (19) into interconnection data (21) having an associated interconnection quality of service. The first quality of service translation means (20) are further arranged for supplying the interconnection data (21) to the interconnection means (22). The interconnection means (22) are arranged for receiving the interconnection data (21) from the first quality of service translation means (20) and for supplying the interconnection data (21) to the second quality of service translation means (24). The second quality of service translation means (24) are arranged for receiving the interconnection data (21) from the interconnection means (22) and for translating the interconnection data (21) into output data (23) having an associated output quality of service. The second quality of service translation means (24) are further arranged for supplying the output data (23) to the second network (16). The gateway (14) is characterized in that the interconnection data (21) further comprise information representative of the input quality of service and in that the second quality of service translation means (24) are arranged for translating the interconnection data (21) into the output data (23) in dependence on the information. By incorporating this information the second quality of service translation means (24) can efficiently map the interconnection data onto the output data.
