Abstract
In a data communication system comprising a plurality of peripherals having respective interfaces, the interfaces having device drivers and being coupled to a common bus for communication with a management system, the interfaces having different real time requirements; an ATM SAR and scheduler employs a predefined PHY level interface with different levels of service, the PHY interface being used as a QOS (Quality of Service) aware common master-slave bus for the peripherals which act as slave devices, whereby respective device driver requirements can be simplified or eliminated. A predefined PHY level interface is the ATM Forum UTOPIA, each peripheral being addressed as a separate UTOPIA slave port. The invention discloses how a system required to support interfaces with differing real time requirements may be supported through the use of a common bus.
